Start with strategic fit
Strategic fit asks whether an option suits the organisation's direction and circumstances. A profitable opportunity can still divert attention from its purpose, weaken its customer promise or require capabilities it cannot develop in time.
Connect the proposal to the mission and intended advantage, the external opportunity, and internal delivery conditions. Include a realistic baseline: what happens if the organisation maintains its current approach? An option's benefits should represent an improvement over that baseline, not simply the revenue of the proposed activity.
Separate requirements from preferences. A requirement is a condition an option must satisfy; a preference helps compare acceptable options. An attractive score should not compensate for failure to meet a mandatory safety requirement or an absolute funding limit.
Concept sources: NASA — 6.8 Decision Analysis — Decision context, criteria, alternatives and uncertainty inform this application to strategic choices.
Use value and effort to screen options
A value/effort assessment is a quick comparison of expected benefit with the work required. Value can include profit, service improvement or progress towards a social purpose. Effort includes money, staff time, coordination and implementation difficulty. Define the time horizon and what “high” means before comparing proposals.
| Expected value and effort | Initial response | What to check |
|---|---|---|
| High value; low effort | Investigate early | Are benefits credible, and are hidden dependencies missing? |
| High value; high effort | Develop a fuller case | Can the organisation fund and manage delivery? |
| Low value; low effort | Consider a small delegated improvement | Does it distract from a more valuable use of time? |
| Low value; high effort | Usually redesign or reject | Is it nevertheless a necessary obligation or enabling investment? |
Concept sources: ASQ — Impact Effort Matrix — Impact/effort screening concept; this comparison table was prepared for these notes.
This is a screening aid, not an automatic approval rule. A small project can appear easy while consuming the same scarce specialist needed by a more valuable initiative.
Choose criteria that reflect the decision
Criteria translate strategy into specific comparisons. Include both financial outcomes and the conditions needed to deliver them. These groups organise useful questions; an organisation would select and define the criteria relevant to its particular decision.
| Evaluation area | Questions to investigate |
|---|---|
| Market opportunity and value proposition | How large is the reachable opportunity? Can demand grow sustainably? What customer benefit makes the offer worth choosing? |
| Financial results | What profit and cash contribution are expected? What do appropriate investment measures, including ROI or IRR, indicate? |
| Distribution and service | Can customers be reached through workable channels and partners? Can enquiries, delivery and after-sales needs be supported? |
| Capabilities, resources and capacity | Are the skills available? What people, funding and equipment are needed? Is there enough available time and throughput? |
| Risk and responsibility | What could prevent success? What are the social and environmental consequences, including corporate social responsibility commitments? |
Concept sources: ASQ — What is a Decision Matrix? and HM Treasury — Use of Multi-Criteria Decision Analysis in options appraisal of economic cases — Selection of relevant financial and non-financial criteria; this business application and grouping were prepared for these notes.
Capability, resources and capacity are different. A bookbinder may know how to restore damaged bindings, own suitable equipment, and still have no spare skilled hours. Funding another machine will not necessarily remove that bottleneck.
Avoid counting the same benefit repeatedly through overlapping criteria. Profit, ROI and IRR are related financial indicators, not three independent reasons that an option creates value. A high percentage return also does not, by itself, establish the greatest total value.
Build a weighted comparison
A weighted criteria evaluation makes priorities and judgements visible. Define a favourable rating scale for each criterion, assess options using evidence, multiply each rating by its weight, then add the results. Weights should total 100% when expressed as percentages.
Keep the direction consistent: a high rating must always mean a more desirable result. For a risk criterion, this means a high rating represents more manageable remaining risk, not greater danger. Record why each rating was awarded.
| Criterion and weight | A: library service | B: personalised covers |
|---|---|---|
| Customer benefit: 40% | 4 | 5 |
| Financial contribution: 35% | 3 | 4 |
| Delivery readiness: 25% | 4 | 2 |
| Weighted total out of 5 | 3.65 | 3.90 |
Concept sources: ASQ — What is a Decision Matrix? — Weighted scoring method; the options, criteria, ratings and calculations are an original worked application.
For A: (4 × 0.40) + (3 × 0.35) + (4 × 0.25) = 3.65. For B: (5 × 0.40) + (4 × 0.35) + (2 × 0.25) = 3.90.
B leads under these assumptions. The 0.25-point advantage does not prove it will succeed, nor mean it earns 0.25 more profit. It is a combined preference score whose meaning depends on the criteria and rating scales.
Test whether the ranking is robust
Sensitivity analysis changes uncertain ratings or defensible weights to see whether the preferred option changes. A close result deserves particular attention. Discuss disagreements rather than adjusting weights until a favoured project wins.
In the bookbinder example, suppose reliable delivery becomes more important. Readiness rises to 40%, customer benefit falls to 25%, and financial contribution stays at 35%. A now scores 3.65 and B 3.45. The ranking reverses. Managers should investigate the cover range's readiness gap and agree the real trade-off before committing resources.
Simple scoring is not the same as a full multi-criteria decision analysis, or MCDA. Formal approaches examine the value of performance differences and may use swing weighting, which considers both the size of an improvement and how much it matters. The simple example above is a discussion tool, not a claim of formal MCDA or a substitute for financial appraisal.

Use business analytics to strengthen the evidence
Business analytics uses data and analytical methods to examine business questions. Option evaluation can combine internal transactions, service records and staff feedback with external customer research, industry information and economic data.
| Type of analytics | Contribution to an option decision |
|---|---|
| Descriptive | Summarises observed results, such as orders, margins and delivery times. |
| Diagnostic | Investigates explanations for those results, checking possible causes rather than merely reporting totals. |
| Predictive | Estimates possible future outcomes, such as demand or cancellation rates, using data and explicit assumptions. |
| Prescriptive | Compares possible actions against an objective and constraints, such as choosing a workload mix within available skilled hours. |
Concept sources: IBM — What is business analytics? and IBM — What is prescriptive analytics? — Analytics categories and constrained decision recommendations; this comparison table was prepared for these notes.
A model recommends actions within its assumptions; it does not determine the organisation's values. Check data coverage, changing conditions and model performance. A relationship between two variables is not automatically evidence that changing one will cause the other to change. Supplement analysis with operational knowledge and targeted trials where appropriate.
Understand the data behind the analysis
Data differs in structure, not simply in whether it is digital.
| Data form | Meaning and business example |
|---|---|
| Structured | Defined fields make records readily comparable: an order table with date, service code and price. |
| Semi-structured | Tags or keys organise information without a fixed relational table: a JSON order event. |
| Unstructured | Content does not follow the analysis table's predefined fields: a customer's description of a damaged book or a photograph. |
Concept sources: AWS — Data lake foundation — Supported data categories and raw/transformed storage; definitions and business examples were prepared for these notes.
A data lake can hold these different forms and retain raw source data alongside versions prepared for analysis. Keeping the original can support later questions that need details excluded from an earlier transformation. Preparation still matters: preserving raw data does not make it accurate or immediately usable.
The organisation needs a catalogue, clear ownership, appropriate access and documented transformations. Without these controls, a large collection can become difficult to interpret or trust. Retention should serve an identified purpose and applicable obligations, rather than an assumption that every item must be kept forever.

Turn evaluation into a defensible recommendation
- Define the decision and requirements
- Screen credible alternatives
- Compare evidence against criteria
- Test uncertain assumptions
- Recommend and record the trade-offs
Concept sources: NASA — 6.8 Decision Analysis — Decision criteria, alternatives, uncertainty and reporting; this condensed flow was prepared for these notes.
The recommendation should explain the preferred option, conditions for proceeding, important uncertainties and why alternatives were less suitable. If the deciding assumption is weak, a focused pilot may be more useful than adding decimal places to the score.
