Quick Questions

Shade in the A or B circle for each question.

1. Which statement best describes feasibility in a software development brief?

A A judgement of whether the project can realistically be completed given time, cost, skills and technology

B A list of every feature the finished software will include

2. A team has the skills but the project needs hardware they cannot get. Which type of feasibility is the problem?

A Technical feasibility

B Economic feasibility

3. A client wants an app built, but the quotes for development are double their budget. Which type of feasibility is the problem?

A Economic feasibility

B Time feasibility

4. A school wants a booking system live by next week, but the work needs about three months. Which type of feasibility is the problem?

A Technical feasibility

B Time feasibility

5. Which question checks technical feasibility?

A Can we afford the total cost of the project?

B Do we have the programming skills and technology needed to build this?

Answer Key

Brief feature: feasibility

Section A: Quick Questions

A — A judgement of whether the project can realistically be completed given time, cost, skills and technology

A — Technical feasibility

A — Economic feasibility

B — Time feasibility

B — Do we have the programming skills and technology needed to build this?

Section B: Match the Pairs

Technical feasibility → Do we have the skills, hardware, software and tools needed to build the solution?

Economic feasibility → Can the project be built and run within the available budget, and are the benefits worth the cost?

A time feasibility check asks whether the project can be finished before the client's deadline. → Time feasibility: 12 weeks of tasks must fit before the 10-week deadline

A feasibility statement in a brief judges whether the project can realistically be done given time, cost, skills and technology. → Feasible: 1 developer, $5000 budget, Python skills, 8 weeks available

Feasibility only checks if the app is fun to use. → Feasibility is not about how enjoyable the app is. It judges whether the project can realistically be completed given time, cost, skills and technology.

Economic feasibility: the team has no Java skills, so the project is not feasible. → Lack of skills is a technical feasibility issue, not an economic one. Economic feasibility is about cost versus budget and benefit.

Section C: Definitions

feasibility — A judgement of whether a project can realistically be completed given its time, cost, skills and technology (technical, economic and time feasibility).

Section D: Fill in the Blanks

Feasibility: technical, economic, time

IF cost <= budget THEN
  economicFeasible ← TRUE
END IF

IF daysNeeded > daysAvailable THEN
  timeFeasible ← FALSE
END IF

Section E: Spot the Error

C — The project is economically feasible when the cost is less than or equal to the budget. The condition should be cost <= budget, not >=.

C — An IF statement needs THEN after the condition. The line should be IF needed <= available THEN.

D — If the team already has the skill the project needs, it is technically feasible. The line should set technical ← feasible.

A — The check starts by assuming the project is feasible and only changes it to false if the cost is over budget. Line 1 should be feasible ← true.

A — The program needs the budget and cost values from the user, so it must use INPUT, not OUTPUT. It should be INPUT budget, cost.
