21 of 51 cards from the Design, Development and Application of Solutions (UK-SPEC Competence B) deck — real questions with worked answers.

1. In UK-SPEC Competence B, what are the three core elements you must establish when first defining a problem?

   The problem itself (the need/objective), the constraints (limits within which a solution must work, e.g. cost, time, regulation, physical), and stakeholder needs (the requirements and expectations of all affected parties).

2. Distinguish between a stakeholder's 'need' and a stakeholder's 'want' in problem definition.

   A need is an essential requirement that must be satisfied for the solution to be acceptable; a want is a desirable but non-essential feature. Separating them prevents scope creep and supports prioritisation.

3. Name three common categories of design constraint.

   Technical/physical (size, weight, performance), economic (budget, whole-life cost), and regulatory/legal (standards, safety, environmental). Others include time, ethical, and resource constraints.

4. What is the difference between a functional and a non-functional requirement?

   A functional requirement specifies what the system must do (a behaviour or function); a non-functional requirement specifies how well it must do it (quality attributes such as reliability, performance, usability, safety).

5. State the characteristics of a well-written requirement (the 'SMART'/quality criteria).

   It should be clear/unambiguous, verifiable/testable, feasible, necessary, complete, consistent (non-conflicting), and traceable. Often summarised as Specific, Measurable, Achievable, Relevant, Traceable.

6. What is requirements traceability and why does it matter?

   Traceability is the documented link from each requirement forwards to design elements, tests and verification, and backwards to its originating stakeholder need. It ensures every requirement is met and verified, and that no unnecessary features are added.

7. What are acceptance criteria?

   Pre-agreed, measurable conditions that a product or deliverable must satisfy to be accepted by the customer/stakeholder. They define the boundary between pass and fail for each requirement.

8. Define a 'success measure' (key performance indicator) and how it differs from an acceptance criterion.

   A success measure/KPI quantifies how well outcomes meet objectives over time (e.g. uptime %, cost saving). An acceptance criterion is a binary pass/fail gate at handover, whereas a success measure tracks ongoing performance against the goal.

9. In scope management, what is the project 'boundary'?

   The defined edge that separates what is inside the project (deliverables, functions, responsibilities) from what is outside it (exclusions, interfaces with other systems), establishing the limits of work and responsibility.

10. Define 'scope creep' and give one technique to control it.

    Scope creep is the uncontrolled growth of project scope after the baseline is set, without corresponding adjustment to time, cost or resources. It is controlled by a formal change-control process that assesses and approves every proposed change.

11. What is a scope statement expected to contain?

    The objectives, in-scope deliverables, explicit exclusions, assumptions, constraints, acceptance criteria, and the key interfaces/boundaries with adjacent systems or projects.

12. List the main factors used to select an appropriate technique, procedure or method for a design task.

    Suitability for the problem, available resources and competence, cost and time, accuracy/reliability required, risk and safety, applicable standards/codes, and compatibility with existing systems.

13. What is concept generation in the design process?

    The divergent, creative phase of producing multiple candidate solution ideas (concepts) before evaluation, using methods such as brainstorming, morphological analysis, TRIZ, and benchmarking, to avoid premature fixation on one solution.

14. What is option appraisal and name one structured tool used for it.

    Option appraisal is the systematic comparison of candidate solutions against weighted criteria to select the best. A common tool is the weighted decision (Pugh) matrix; others include cost-benefit analysis and SWOT.

15. How does a weighted decision matrix (Pugh matrix) work?

    Each option is scored against a set of evaluation criteria; each criterion has a weight reflecting its importance. The score is multiplied by the weight and summed per option: $S=\sum_{i} w_{i} r_{i}$. The highest total identifies the preferred option.

16. What is the purpose of detailed design following concept selection?

    To convert the chosen concept into a fully specified, buildable solution: dimensions, materials, tolerances, interfaces, components and documentation sufficient for manufacture, construction or implementation.

17. What is engineering tolerance?

    The permissible total variation in a dimension or property: the difference between the maximum and minimum acceptable limits. For a size $D$ with upper limit $U$ and lower limit $L$, tolerance $T = U - L$.

18. Why should tolerances be specified as widely as the design allows?

    Tighter tolerances increase manufacturing cost, scrap and inspection effort. Specifying the loosest tolerance that still meets functional requirements minimises cost while ensuring fit, form and function.

19. What is tolerance stack-up (accumulation)?

    The cumulative effect of individual part tolerances on an assembly. Worst-case stack adds them arithmetically: $T_{total}=\sum_{i=1}^{n} T_{i}$; statistical (RSS) stack uses $T_{total}=\sqrt{\sum_{i=1}^{n} T_{i}^{2}}$.

20. What does Design for Manufacture (DFM) aim to achieve?

    To design a product so it is easy, cheap and reliable to make: minimising part count, using standard components and processes, simplifying geometry, and designing for the chosen manufacturing method to reduce cost and defects.

21. What is Design for Maintainability (DfM/maintenance)?

    Designing equipment so it can be inspected, serviced and repaired quickly and safely: good access, modularity, standard fasteners, diagnostic features and easily replaceable components, reducing mean time to repair.
