Building a Business Case

Free Preview

Covers building a procurement business case in L4M8: options, costs and benefits, risks, whole-life considerations, stakeholder needs and a justified recommendation. Capital-appraisal methods are optional enrichment unless the task supplies the necessary data.

Building a Business Case in Practice

This is an L4M8 application page. Business-case foundations — needs analysis, cost-benefit analysis, breakeven, option appraisal — are covered in depth in L4M2 LO1. This page focuses on applying those tools in a real procurement scenario.

Where This Sits in the Procurement Cycle

The business case converts an organisational need into a funded, approved decision to source externally. It draws mainly on the first three stages of the CIPS Procurement Cycle: stage 1 (Define Business Needs and Develop Specification), stage 2 (Market Analysis and Make or Buy Decision) and stage 3 (Develop the Strategy and Plan).

L4M8 questions use the CIPS Level 4 command words (for example Describe, Explain, Analyse, Propose). Follow the word on your paper; whichever it is, weigh proceeding to procurement against the alternatives (make internally, do nothing, lease rather than buy).

Source cross-references: L4M2 LO1 (business case, option appraisal); L4M4 LO1 (make-or-buy); L4M1 LO2 (CIPS Procurement Cycle, stages 1–3).

Applying the Six Components

1. Introduction / executive summary — Identify the scenario organisation's problem, state your recommended approach, and name the analytical tools you will use (WLC, CBA, sensitivity analysis).

2. Background and context — Apply specific scenario details: statutory obligations, budget cycles, governance requirements. Do not write a generic definition.

3. Options analysis — minimum three options

  • Do nothing: Quantify the cost of inaction (penalty, asset failure risk, inefficiency). Treat it seriously — dismissing it without analysis weakens the options appraisal.
  • Minimum option: Cheapest or least disruptive — extending existing contracts, leasing rather than buying.
  • Recommended option: Best risk-adjusted value over the appropriate time horizon. For capital expenditure, reference whole-life cost (L4M7), not purchase price alone.

4. Cost-benefit analysis — Apply all four tools from L4M2 LO1 to the scenario:

ToolApplied focus
Cost-benefit comparisonQuantified costs vs benefits at the scenario's scale
Affordability and cash flowDoes the option fit the budget cycle? For a public body, flag capital/revenue distinction
Sensitivity analysisIdentify the one or two assumptions most likely to change and show how they affect the recommendation
Total Cost of Ownership / WLCInclude acquisition, operation, maintenance, training, and disposal (L4M7 LO3)

Apply the tools to the scenario rather than listing them without connecting them to it.

5. Risk assessment — Identify scenario-specific risks, not a generic list. Public sector: PA-2023 compliance risk, supplier dependency, budget risk. Private sector: supply chain disruption, currency risk, specification inadequacy. Always propose a mitigation.

6. Recommendation — Specific to the scenario organisation. Name the procedure, award criteria weighting, and rationale: "Northgate Housing Trust should use an open procedure under the Procurement Act 2023, advertising on the Find a Tender Service (FTS), with award criteria weighted 60% on whole-life cost and 40% on sustainability — given the Trust's Net Zero 2035 commitment."

Make vs Buy

Apply make-or-buy to the specific organisation and context, not generic factors.

Key test: is this a core competency? If central to competitive advantage, make internally to preserve control. If non-core (cleaning, IT maintenance, logistics), outsource to free resources.

Public-sector caution: outsourcing a service may trigger TUPE (the Transfer of Undertakings (Protection of Employment) Regulations 2006, separate legislation from the Procurement Act 2023) when staff transfer to the supplier. Name both TUPE and PA-2023 where a public-sector outsourcing scenario falls under the Act.

Integration with Other Modules

  • L4M3 (Contracting): Connect the business case to a contract type — fixed price for a stable specification, cost-plus for uncertain scope, framework for repeat call-off.
  • L4M7 (Whole Life Asset Management): For capital items, the option appraisal must use WLC, not purchase price.
  • L4M4 (Ethical Sourcing): Where the case involves an overseas source, include ESG criteria and supplier code-of-conduct requirements.
  • L4M5 (Negotiation): Where direct negotiation is recommended over competitive tender, state why (sole source, urgency, proprietary).

Common Mistakes

  • Listing structure without applying it to the scenario — the task is application, so an unapplied list leaves the question only part-answered.
  • Omitting "do nothing" — treat it as a genuine option with a stated cost.
  • Using purchase price as the sole financial measure for capital items — signals L4M7 knowledge gaps.
  • Generic risk lists without mitigations.
  • Outdated public-procurement terminology (OJEU, MEAT, PQQ) — FTS has replaced OJEU/TED since 1 January 2021; for procurements under PA-2023 (in force from 24 Feb 2025) use MAT and conditions of participation; procurements begun under the previous law continue under it, so match the scenario.

Key Terms

Business CaseA formal document that justifies a proposed procurement by comparing benefits, costs, risks, and options to support decision-making.
Cost-Benefit AnalysisA structured comparison of quantified and non-financial benefits against costs and risks to support a justified procurement recommendation.
Make or Buy DecisionThe strategic choice between producing goods/services internally versus purchasing from external suppliers — driven by cost, capability, capacity, and strategic importance.
Total Cost of Ownership (TCO)A comprehensive analysis covering acquisition, operation, maintenance, and disposal costs over the entire lifecycle — not just purchase price.
Options AppraisalThe structured comparison of at least three feasible approaches (do nothing, minimum investment, recommended solution) before selecting the preferred course of action.
PESTLE AnalysisPolitical, Economic, Social, Technological, Legal, Environmental — a framework for analysing external macro-environment factors affecting a procurement decision or strategy.
Sensitivity AnalysisTesting how the outcome of a financial model changes when key assumptions (e.g., demand, price, discount rate) are varied — identifies which variables most affect the decision.
Return on Investment (ROI)A financial ratio measuring the net benefit of a procurement decision relative to its cost, expressed as a percentage: (Net Benefit ÷ Cost) × 100.
Stakeholder MappingThe process of identifying and categorising stakeholders by their level of power and interest (using tools such as the Mendelow matrix) to determine engagement strategy.
Procurement StrategyA high-level plan defining how an organisation will use procurement to achieve organisational objectives — covering sourcing models, supplier relationships, risk appetite, and sustainability goals.
Gateway ReviewA structured decision point within a procurement process where a panel assesses whether a project is ready to proceed to the next stage — common in public sector procurement.
Social Value Act 2012UK legislation requiring public bodies to consider how procurement can improve economic, social, and environmental well-being in their local area.

Common Traps

  • Always present at least 3 options in a business case (do nothing, minimum, recommended) — presenting only one option weakens the appraisal.
  • TCO is more credible than purchase price alone — always demonstrate lifecycle cost awareness and include hidden costs in your business case.
  • L4M8 is an APPLICATION module — never just list theory. Every model or framework must be explicitly applied to the scenario details provided in the question.
  • Sensitivity analysis is NOT the same as risk assessment — it tests financial assumptions, while risk assessment identifies and evaluates threats.
  • A business case must address stakeholder concerns, not just financial numbers — use Mendelow or RACI to show stakeholder awareness in your answer.
