Providers in 2026: Who to Consider
Procurement managed services has undergone a fundamental shift in 2026. What began as a cost-reduction play — outsourcing transactional procurement activities to lower-cost service providers — has evolved into a strategic capability model where the most valuable managed services providers deliver AI-powered process transformation, category expertise, and technology ownership alongside operational execution. The five distinct engagement models — from transactional process BPO through to technology-led managed services — make very different trade-offs between cost, control, technology ownership, category expertise, and the pace at which AI-driven procurement transformation can be achieved. Choosing the wrong engagement model — the right provider for the wrong use case — is a more common failure than choosing the wrong provider for the right use case.
The Five Procurement Managed
Services Engagement Models
Procurement managed services is not a single service type — it is five distinct engagement models that differ fundamentally in what the provider owns, what the enterprise retains, and what the engagement is designed to achieve.
Selecting the wrong engagement model produces a managed services programme that is well-executed for the wrong objective. Understanding the five models before selecting a provider is the most important step in managed services procurement.
1. Transactional Process BPO
Day-to-day procurement transaction execution — purchase order processing, invoice management, supplier onboarding administration, catalogue management, and helpdesk for procurement queries. Provider staffs and manages the transactional procurement team using their own processes and technology.
Moderate AI transformation — process efficiency, not strategic capability building2. Category Management as a Service
Specialist category expertise applied to defined spend categories — market intelligence, sourcing event execution, supplier negotiation, contract management, and ongoing category performance management. Provider brings category-specific expertise the enterprise does not have internally.
High AI transformation — AI-native S2P platforms drive higher savings rates and faster sourcing3. Technology-Enabled Managed Services
Procurement managed services delivered on a defined technology platform — the provider implements, manages, and continuously improves the enterprise's S2P platform as part of the service. Technology and service delivery are bundled under one provider accountability.
Very high AI transformation — autonomous tail spend negotiation, AI intake, AI sourcing as service4. Procurement Transformation + Steady State
A phased engagement — initial transformation phase that redesigns procurement processes, implements technology, and builds capabilities, followed by a steady-state managed services phase that operates the transformed programme. Often led by a strategy and operations consulting firm.
High AI transformation — transformation phase implements AI-native tech; steady state sustains it5. Tail Spend Management as a Service
Managed services focused specifically on tail spend categories — the high-volume, low-value indirect spend that falls below the sourcing threshold for internal category managers. Provider manages supplier identification, negotiation, catalogue management, and autonomous purchasing for tail categories. Zycus ANA delivers autonomous tail spend negotiation within this model.

Build vs. Buy vs. Partner:
When Managed Services Is the Right Answer
The decision to engage a procurement managed services provider is not primarily a cost decision — it is a capability and speed-to-value decision. Four conditions indicate that managed services is the stronger answer over building or buying independently.
| Condition | Build It Yourself | Buy Software Only | Procurement Managed Services | Why Managed Services Wins Here |
|---|---|---|---|---|
| Procurement capability gap is large and urgent | Building world-class procurement capability from scratch — hiring specialists, implementing technology, redesigning processes, managing change — takes 3–5 years and requires executive commitment that may not be sustained through the typical leadership cycle | Technology alone does not close a capability gap — software implementation without process design, change management, and category expertise produces low adoption and modest results; Gartner estimates 40–60% of S2P implementations deliver below 50% of planned value due to capability gaps | A managed services provider brings the capability immediately — technology, process, category expertise, and people — and delivers value from the start of the engagement while transferring capability to the internal team over the contract period | Speed to value and capability risk transfer: managed services compresses the 3–5 year build timeline to 6–12 months to initial value delivery, while allocating execution risk to the provider rather than the internal team |
| AI-native procurement transformation is the objective | Building an internal AI-native procurement capability requires hiring AI/ML specialists, procuring and integrating AI tools, managing AI model training and validation, and sustaining the capability through technology evolution — a significant ongoing investment | Purchasing AI-native S2P software provides the capability but requires internal implementation, change management, and optimisation resources. Most enterprises underutilise AI features for 12–18 months after go-live because adoption and optimisation are not resourced | Technology-led managed services on an AI-native platform delivers AI transformation as part of the service — the provider implements ANA, configures autonomous intake orchestration, trains AI classification models, and optimises AI performance continuously as part of the service SLA | AI capability is continuous: managed services providers sustain AI performance, adapt configurations as the enterprise's spend evolves, and introduce new AI capabilities as the platform develops — without requiring enterprise IT investment in AI expertise |
| Procurement headcount is constrained but spend is growing | Hiring procurement professionals to match growing spend coverage is expensive, slow, and creates a capacity model that scales linearly with spend volume — the opposite of how modern procurement should scale | Software scales better than headcount, but software without people cannot execute strategic sourcing events, manage supplier relationships, or respond to procurement emergencies | Managed services scales procurement capacity without headcount growth — the provider adds resource from their talent pool as managed spend grows, without the enterprise absorbing recruitment, training, or employment costs. AI automation further reduces headcount required per dollar of managed spend | Capacity on demand: managed services converts fixed procurement headcount cost into variable managed spend cost — scaling up for sourcing pipeline execution peaks and scaling back as the pipeline stabilises |
| Category expertise in specific spend areas is insufficient | Building deep category expertise internally in categories like IT, professional services, facilities, contingent labour, and logistics requires hiring experienced category managers for each category — a multi-year investment in recruiting, retention, and knowledge management | Category-specific AI tools improve analysis and benchmarking but do not replace the market knowledge and negotiation experience of a specialist category manager with 15 years in the category | Category management as a service brings expert category managers with deep market knowledge, supplier relationships, and benchmarking intelligence that would take years to develop internally. Specialist providers have negotiated the same category for hundreds of clients and know where the savings are before the first supplier meeting | Immediate expertise without years of development: category managed services providers deliver benchmark-quality results from engagement start, not after 2–3 years of learning curve |
Procurement Managed Services
Provider Categories in 2026
The procurement managed services market in 2026 is served by four distinct provider categories — each originating from a different primary discipline and each making different trade-offs between technology ownership, category expertise, transformation depth, and cost model flexibility. The originating discipline is the strongest predictor of where each provider category excels.

How Zycus Delivers Technology-Led
Procurement Managed Services
Zycus Managed Services is structurally different from every other managed services model in one fundamental respect: the same team that built the AI platform that delivers the managed service also manages its deployment, optimisation, and continuous improvement. There is no integration gap between what the platform can do and what the managed services team delivers, because both are owned by the same organisation and governed by the same accountability. This unified ownership model eliminates the most common managed services failure mode: a provider who has excellent process management capability but limited ability to extract maximum value from the technology because they are a user of the platform, not the owner. When Merlin ANA releases a new negotiation capability, Zycus managed services clients receive it immediately. When AI spend classification improves its accuracy on a new category type, managed services clients benefit automatically. The managed services contract is an SLA on both platform performance and procurement outcomes.
AI-Native Procurement Execution as a Managed Service
Zycus delivers Merlin ANA autonomous negotiation, Merlin Intake Agent orchestration, and AI sourcing event execution as managed services capabilities — not as software features that the enterprise must adopt internally. The managed services team configures ANA parameters, trains the AI on enterprise-specific spend patterns, monitors negotiation outcomes, and continuously expands the scope of autonomous execution to new tail spend categories. Enterprises receive the value of Level 4 agentic AI procurement without the internal change management challenge of adopting autonomous AI purchasing — the managed services team manages the transition from buyer-directed to AI-executed procurement.
Merlin ANA · Intake Agent · AI sourcing · Level 4 agentic procurement — delivered as service, not as features for internal adoptionS2P Platform Implementation and Continuous Optimisation
Zycus managed services includes implementation of the full Merlin Agentic Platform — spend analytics, eSourcing, Contract CLM, supplier management, eProcurement, eInvoicing — with ongoing platform management, user adoption programmes, and continuous feature deployment as part of the service contract. The enterprise receives a continuously improving S2P capability rather than a point-in-time implementation that depreciates as the platform evolves without optimisation investment.
Full Merlin Agentic Platform · ongoing management · continuous feature deployment · no depreciation from unoptimised implementationSpend Intelligence and Category Savings Identification
The Zycus managed services team applies AI spend analytics to continuously identify savings opportunities across all spend categories — benchmark comparisons surfacing categories priced above market, preferred supplier compliance gaps generating savings leakage, and tail spend fragmentation creating autonomous negotiation opportunities. Savings opportunity identification is provided as a managed service output: a prioritised savings pipeline with estimated value, recommended action, and implementation timeline, updated monthly from live spend data.

Zycus manages supplier onboarding, qualification, performance monitoring, and compliance governance as part of the managed services scope — maintaining the supplier qualification database, monitoring certification currency, managing corrective action programmes, and enforcing compliance at the purchasing layer. Enterprises with large, complex supplier bases receive systematic supplier governance without building the internal team required to maintain it at scale.
Onboarding · qualification · performance monitoring · certification currency · CAP management · purchasing-layer enforcementProcurement Analytics and Executive Reporting
Zycus managed services delivers structured procurement performance reporting — savings delivery against programme targets, maverick spend rates by category and business unit, preferred supplier compliance performance, sourcing pipeline value and progress, and AI automation adoption rates — as a monthly managed service output. CPOs receive board-ready procurement performance intelligence without requiring internal data engineering to assemble it.

Service Delivery Dimensions
Eleven service delivery dimensions comparing the four provider categories — this is not a software feature comparison, it is a service model comparison that reflects how each provider category actually delivers procurement value in production engagements.
| Service Delivery Dimension | Technology-Led (Zycus) | Procurement BPO | Strategy & Ops Consultants | Specialist Category |
|---|---|---|---|---|
| Technology platform ownership | ✅ Owns the S2P platform — single accountability; improvements deploy automatically | ⚠️ Varies — some own platforms, others use client tech. Technology is delivery tool, not differentiator | ⚠️ Partner — implements client's chosen platform. Integration and implementation, not ownership | ❌ Lean — client platform or specialist tools. Expertise, not technology, is the differentiator |
| AI and autonomous procurement capability | ✅ Native — Merlin ANA, Intake Agent, AI sourcing built into platform the service runs on | ⚠️ Advancing — AI for invoice processing, spend analytics, PO automation. Component of delivery | ⚠️ AI via platform partners and accelerators. Depends on platform implemented and its optimisation | ❌ Emerging — AI into benchmarking and spend analysis. Human expertise still primary driver |
| Category expertise depth | ✅ Deep for categories managed on Zycus platform — spend analytics + ANA market pricing data | ✅ Strong across indirect categories — dedicated category managers with industry expertise | ✅ Variable by firm — broad category coverage; depth in IT and professional services strongest | ✅ Core strength — deepest category-specific intelligence and negotiation expertise |
| Time to initial value delivery | ✅ 6–12 weeks to first AI-generated savings via SCALE — AI classification + ANA + reporting live | ⚠️ 8–16 weeks for transactional BPO; category programmes first savings 10–16 weeks | ❌ Transformation: 12–24 months. Steady-state following transformation: 6–12 months | ✅ Category: first savings 8–14 weeks — specialist firms move quickly with category knowledge ready |
| Cost model flexibility | ✅ Outcome-based options — savings share, per-transaction, subscription. AI reduces unit cost over time | ✅ Per-transaction and FTE-based for BPO; savings share and retainer for category. Volume-based pricing | ⚠️ Project and retainer fees for transformation; retainer and outcome-based for steady-state. Consulting rates | ⚠️ Retainer and savings share. Premium-priced vs BPO; premium reflects savings delivery |
| Scalability — managing growing spend volume | ✅ High — AI automation scales without proportional headcount growth | ✅ High — large low-cost delivery teams enable volume scaling; category scaling needs specialists | ⚠️ Moderate — global scale but resource-intensive; less efficient per dollar of managed spend than BPO | ❌ Limited — expertise-intensive; cannot scale without diluting category depth |
| Governance and performance reporting | ✅ Structured monthly reporting — savings, AI rates, analytics, compliance — auto-generated from live data | ✅ Strong operational reporting — transaction volumes, SLA, cost per transaction, onboarding time | ✅ Comprehensive frameworks for board-level governance: maturity scorecard, savings, functional ROI | ⚠️ Savings delivery primary metric. Benchmark reporting unique; less depth in operational process metrics |
| Exit and insourcing flexibility | ✅ Enterprise retains all data, suppliers, contracts on platform — clean exit; no data migration required | ⚠️ Contract exit complexity varies. Data portability depends on technology stack ownership | ✅ Transition back to internal is designed feature of transformation + steady-state models | ⚠️ Expertise partially transferable via knowledge management; exit requires internal capability build |
| Regulatory and compliance coverage | ✅ S2P compliance native — supplier qualification at PO, ESG monitoring, contract and policy enforcement | ⚠️ Compliance-capable but operates within enterprise's compliance framework; regulatory expertise varies | ✅ Strong regulatory advisory — global consultants strong on regulated industries. Core competency | ⚠️ ESG and supply chain compliance emerging; strongest for regulated categories (pharma, food, defence) |
| Innovation and technology roadmap | ✅ Continuous — Zycus's Merlin AI agents and analytics roadmap directly benefits managed services clients | ⚠️ Dependent on platform partner or technology partner roadmaps. Innovation less direct | ⚠️ Broad tech ecosystem relationships; can bring emerging tech but not driving specific platform roadmap | ⚠️ Innovate in data and benchmarking — pricing databases, category models. Less platform innovation |
| Global delivery and geographic coverage | ✅ 150+ country client base with Merlin delivered consistently — cloud-native global platform delivery | ✅ Strong — large BPO providers have low-cost delivery centres and global client-facing teams | ✅ Global delivery at enterprise scale — offices in every significant business geography | ❌ Typically strongest in home geographies; global coverage more limited than consultants or BPO |
Procurement Managed Services ROI:
What the Benchmarks Show
Annual value for a representative enterprise with $500M addressable procurement spend engaging a managed services provider — across three primary value levers.
| ROI Lever | Engagement Type | How Managed Services Delivers It | Benchmark Source | Annual Value ($500M Spend) |
|---|---|---|---|---|
| Category savings above self-managed baseline | Category MSSpecialist delivery | Managed services providers deliver higher savings rates than self-managed procurement — specialist category knowledge, established supplier benchmarks, and dedicated sourcing resource produces 8–12% savings on managed spend compared to 4–6% for self-managed. The incremental savings above the self-managed baseline is the primary financial justification for managed services investment. | Hackett Group | $10–30M annually on $500M addressable spend — the 4–6% incremental savings rate above the self-managed baseline; value concentrated in the managed spend categories where the provider's expertise advantage is greatest. 2–3x the savings rate of in-house built capability. |
| Operational cost reduction — procurement function efficiency | Transactional BPOHeadcount displacement | Managed services replaces fixed internal headcount with variable managed spend cost — eliminating recruitment, training, benefits, and management overhead for the replaced roles. AI automation within the managed services model further reduces cost per managed transaction as autonomous AI execution replaces buyer-directed processing. | Hackett Group | $3–8M annually in reduced procurement operations cost — at 20 procurement staff displaced by managed services (fully loaded cost $200K/head), $4M in direct cost reduction; AI automation delivering incremental efficiency reduces managed cost per transaction by 30–50% over the contract term. |
| Technology-enabled value — AI savings from autonomous execution | Technology-Led MSAI-native platform | Technology-led managed services on an AI-native platform delivers savings that purely human-executed managed services cannot achieve — Merlin ANA's autonomous tail spend negotiation identifies and captures above-market pricing in categories that are individually too small for buyer attention but collectively significant. AI spend analytics surfaces savings opportunities that manual category review misses. AI intake enforcement reduces maverick spend. | Zycus benchmarks | $5–15M annually from AI-specific value: ANA tail spend negotiation ($3–8M at 3–5% on $100–175M tail spend), maverick spend leakage recovery ($10–20M from enforcing preferred supplier compliance from 8–12% to under 2%), AI contract compliance monitoring recovering 20–30% of identified savings leakage. |
How to Evaluate Procurement
Managed Services Providers in 2026
Managed services provider evaluation requires assessing both what the provider will deliver and how — the engagement model, the technology foundation, the governance structure, and the exit provisions that determine whether the managed services partnership creates lasting value or creates a dependency that is difficult to exit.
| Evaluation Criterion | Weight | What to Assess — The Specific Test |
|---|---|---|
| Engagement model clarity — are you buying the right service? | 22% | Before evaluating providers, confirm which of the five engagement models you need: transactional BPO, category management as a service, technology-enabled managed services, transformation + steady state, or tail spend management as a service. Each model has fundamentally different success criteria, provider category strengths, cost models, and exit provisions. Evaluating technology-led providers against criteria designed for transactional BPO — or vice versa — produces a misleading comparison. The engagement model choice should precede the provider shortlist, not follow it. The test: can the provider articulate precisely which of these five models they are proposing, what they own versus what the enterprise retains, and what success looks like at contract end? Providers who blur the model boundaries to appear comprehensive are typically strong in one model and managing their weakness in others. |
| Technology platform accountability | 18% | The most consequential structural question in managed services evaluation: does the provider own and continuously develop the technology platform that the managed service is delivered on, or do they use your technology or a third-party platform? Technology-owning providers have a unified accountability — if the technology underperforms, the provider's service SLA is affected and they fix it. Technology-using providers (consulting firms and platform-agnostic providers) have a split accountability — the technology is your asset or a third party's, and service performance disputes may be redirected to technology quality as a defence. Ask specifically: what happens to the service SLA if the technology platform has an outage or underperforms? Who is accountable for technology optimisation over the contract term, and how is that measured? |
| AI capability — production evidence, not roadmap | 16% | Require production evidence of AI procurement capability from the provider's existing client base: how many clients are using autonomous AI procurement execution today, what is the autonomous execution rate as a percentage of total transaction volume, what savings outcomes have AI-negotiated categories delivered, and what is the false positive rate for AI-generated purchasing decisions that required human override? Providers with genuine AI capability can point to production deployments with measurable outcomes. Providers who describe AI capability as part of their roadmap or reference AI features in their platform that are not active in managed services delivery are selling future capability at current prices. For AI-autonomous procurement specifically (ANA), require a live demonstration on a sample of your actual tail spend data. |
| Savings delivery evidence in your categories | 14% | Require category-specific savings delivery references — not aggregate programme savings across all clients, but documented savings outcomes in the specific categories you are proposing to manage. A provider claiming 8% average savings across 200 clients tells you nothing about their performance in professional services, IT hardware, facilities, or contingent labour specifically. Require: savings rate achieved in the category, starting price position relative to market benchmark, contract implementation timeline, and whether savings were sustained at the first contract renewal. The most reliable predictor of category managed services value is demonstrated category performance, not programme-level averages. |
| Governance, reporting, and exit provisions | 16% | Three governance questions determine whether a managed services programme remains strategically valuable or drifts into managed dependency: (1) Performance visibility: does the provider deliver structured monthly reporting on savings delivery, spend analytics, supplier compliance, and AI automation rates — or is performance information only available when you ask for it? (2) Governance structure: is there a defined joint governance process with enterprise and provider stakeholders at category, programme, and executive levels — or is governance ad hoc and reactive? (3) Exit provisions: does the enterprise own all procurement data, contracts, supplier relationships, and process documentation in a format that supports insourcing without data migration? What is the transition timeline and cost at contract end? Managed services programmes with weak exit provisions create long-term dependency regardless of performance quality. |
| Cultural and operational fit | 14% | Procurement managed services is an intensive operating partnership — the provider's team works alongside (or instead of) internal procurement staff, interacts with stakeholders across the enterprise, and represents the procurement function in supplier relationships. Cultural fit matters more than in a software selection. Assess: does the provider's operating model align with the enterprise's procurement culture — centralised governance or distributed decision-making? Does the provider communicate in the enterprise's language or default to consulting jargon? Has the provider worked in the enterprise's industry, and do they understand the stakeholder dynamics of the enterprise's category managers? A technically superior provider who is a poor cultural fit will underperform against a well-aligned provider with slightly lower benchmark savings rates. |

Procurement managed services is a model where a third-party provider takes operational responsibility for a defined scope of procurement activities — from transactional processing through to strategic category management — on behalf of the enterprise, typically delivering both people and technology as part of the service. It differs from traditional outsourcing in two ways: scope and intent. Traditional procurement outsourcing was primarily a cost reduction exercise that transferred transactional volume to a lower-cost provider without changing the underlying procurement capability. Modern procurement managed services — particularly technology-led and category management models — are designed to deliver capability improvement, AI transformation, and savings outcomes that exceed what the enterprise could achieve by managing the same spend internally. The best managed services programmes are designed to transfer capability back to the enterprise as the partnership matures, not to create permanent dependency.
The fundamental difference is accountability and advancement. In procurement BPO, the provider manages your procurement processes — typically on your technology or their own platform — and is accountable for process execution quality and cost efficiency. The technology and the service are separate contracts or, where bundled, managed by different teams. In technology-led managed services (Zycus's model), the provider owns the AI platform that the managed service is delivered on — creating unified accountability for both technology performance and service outcomes, and ensuring that platform improvements directly advance service capability without requiring the enterprise to manage platform upgrades. When Merlin ANA adds a new negotiation capability, Zycus managed services clients receive it as part of their service. When a BPO provider's technology partner releases a new feature, the BPO must deploy it as a separate project — often months or years after release.
AI fundamentally changes managed services economics in two ways. First, it improves the savings-to-cost ratio: AI autonomous procurement execution (Merlin ANA) captures savings in tail spend categories that are individually too small to justify buyer time but collectively represent 20–35% of total spend. A managed services programme with AI autonomy delivers savings at zero incremental cost per category negotiated — the AI negotiates 24/7 within pre-approved parameters. Second, it changes the cost model: traditional managed services cost scales with transaction volume because people execute transactions. AI-enabled managed services cost scales more slowly because AI handles the volume growth — managed services providers can grow managed spend scope without proportional headcount growth, improving the economics for both provider and client over the contract term.
Tail spend management as a service is best delivered by technology-led managed services providers with genuine AI autonomous negotiation capability — specifically platforms like Zycus with production Merlin ANA deployment. Tail spend is defined by being individually too small for buyer attention but collectively significant — which makes it ideally suited to AI execution rather than human-managed category management. Traditional BPO providers can manage tail spend transaction volumes efficiently, but they cannot deliver the 3–5% negotiated savings per category that AI-autonomous negotiation achieves because human negotiators require per-category economics that tail spend categories do not support. Specialist category firms are overspecified for tail spend — their expertise premium is wasted on categories where the individual spend is below the threshold that warrants specialist involvement. Technology-led managed services on an AI-native platform is the engagement model that matches the economics of tail spend to the appropriate execution mechanism.
Best-in-class managed services programmes define a clear internal/external boundary that retains the enterprise's strategic value while externalising execution. Enterprises should typically retain: (1) procurement strategy and policy — which categories to manage, what the savings targets are, and what the supplier relationship philosophy is; (2) strategic supplier relationships — the enterprise's top 20–30 strategic suppliers should be managed by internal executives with the managed services provider supporting the operational relationship; (3) spend authority and commercial approval — final commercial approval for significant contracts should remain with the enterprise, with the managed services provider executing the sourcing process; (4) internal procurement talent for strategic categories — enterprises should keep or build procurement professionals for their most commercially sensitive spend categories rather than fully externalising their procurement thinking. What is appropriate to externalise: transactional execution, tail spend management, category analysis and sourcing event management for non-strategic categories, and the technology platform that supports all of the above.
Implementation timelines vary significantly by engagement model. Technology-led managed services with SCALE implementation framework: 6–12 weeks to initial value delivery — AI spend classification producing the first spend cube, initial Merlin ANA autonomous negotiations live, and procurement reporting operational within the first quarter. Full managed services scope with all categories and modules active: 3–6 months. For category management as a service: first sourcing event in a new category typically launches within 8–12 weeks of engagement start; first savings delivered at award, typically 4–6 weeks after launch. For transformation + steady-state consulting engagements: transformation phase 12–24 months; transition to managed services operation 3–6 months following transformation completion. The fastest path to initial value from managed services is technology-led models with AI-native platforms — the combination of rapid implementation methodology and pre-built AI capabilities compresses the time from contract signature to measurable procurement impact.
Procurement managed services performance should be measured across four dimensions: (1) Savings delivery — actual savings captured versus programme targets, broken down by category and sourcing event, with methodology transparency (are savings calculated against market benchmark or prior-year price?); (2) Operational excellence — process SLA performance (sourcing event cycle time, PO cycle time, invoice processing time, supplier onboarding time) and quality metrics (contract accuracy, supplier complaint rate); (3) AI automation adoption — for technology-led providers, the proportion of transactions executed autonomously, ANA negotiation coverage and savings rate, and intake orchestration automation rates; (4) Strategic value — procurement influence on spend (percentage of addressable spend under management), savings sustainability at renewal (are year-1 savings maintained in year 2 and 3?), and procurement capability transferred to internal teams over the contract term. Providers who only report savings delivery without operational, automation, and strategic metrics are optimising reporting for the metric where their performance is strongest rather than providing a complete performance picture.
