Quick Questions

Shade in the A or B circle for each question.

1. A school canteen app problem has parts: online ordering, stock tracking, staff rostering. Which is a sound way to pick the aspect to develop?

A Compare each part by importance to stakeholders and how feasible it is to build in the time available

B Pick the part that sounds most impressive, even if you can't finish it

2. Which statement of a chosen aspect is clearer?

A The solution will develop an online ordering system so students can pre-order lunch before school.

B The solution will fix the canteen and make everything better for everyone.

3. Why must you link the chosen aspect to stakeholder needs?

A So you can avoid talking to stakeholders for the rest of the project

B So the part you develop solves something the users and other stakeholders actually need

4. A part is very important but needs skills and tools you don't have, and you only have 10 weeks. What does this show?

A It has low feasibility, so it may not be the best aspect to choose

B Importance is all that matters, so you should choose it anyway

5. How many aspects of the problem does your solution develop as its chosen aspect?

A Every sub-problem identified

B One manageable part

Question 1

A best ← 0

B for each part in parts

C score ← imp + feas

B need ← "fewer queues"

C aspect ← "Colour theme"

D print "Meets: " + need

Question 4

A top ← 100

B for each p in parts

C if p.score > top then

D top ← p.score

Question 5

A problem ← "Slow canteen service"

B aspect ← "Fix everything"

C print "Chosen: " + aspect

Answer Key

Choosing the aspect of a problem to develop

Section A: Quick Questions

A — Compare each part by importance to stakeholders and how feasible it is to build in the time available

A — The solution will develop an online ordering system so students can pre-order lunch before school.

B — So the part you develop solves something the users and other stakeholders actually need

A — It has low feasibility, so it may not be the best aspect to choose

B — One manageable part

Section B: Match the Pairs

Chosen aspect: online canteen ordering → A clear statement of the one part of the problem the solution will develop

Importance: High | Feasibility: High → A strong candidate for the chosen aspect because it matters a lot and can be built in the time and skills available

The aspect is linked to a stakeholder need so the choice is justified → Justification: Students need shorter queues, so ordering ahead is the aspect to develop.

Parts of a problem are compared by importance and feasibility before one is selected → Part A: Importance 5, Feasibility 2 | Part B: Importance 4, Feasibility 5 -> choose Part B

Chosen aspect: develop the whole school app with bookings, payments, timetables and messaging → The choice is not one manageable part. It tries to cover the whole problem, so the scope is too big and unclear.

Chosen aspect: the timetable page, because I think it looks fun to code → The choice is not justified by stakeholder needs or by importance and feasibility. It is only a personal preference.

Section C: Definitions

Chosen aspect — The one manageable part of a problem your solution will develop, picked by importance and feasibility, linked to stakeholder needs, and justified.

Section D: Fill in the Blanks

IF importance = "high" AND feasible = TRUE

score ← importance + feasibility

IF score > bestScore THEN
    bestScore ← score
    chosenAspect ← aspect

reason ← "Meets need of " + stakeholder

print "Chosen: " + chosenAspect

Section E: Spot the Error

D — To find the most important and feasible part, you update best when the new score is greater than best. Using < would keep the lowest score. It should be: if score > best then.

B — A part is feasible when its cost fits within the budget. The test marks it feasible when it costs more than the budget. It should be: if cost <= budget then.

C — The chosen aspect must be linked to a stakeholder need. A colour theme does nothing for fewer queues. It should be an aspect like "Online ordering" that addresses the need.

A — The starting value must be low (0) so the first part's score can beat it. Starting at 100 means no part is ever chosen. It should be: top ← 0.

B — The chosen aspect must be stated clearly as one manageable part of the problem. "Fix everything" is vague and far too broad. It should name one specific part, such as "Online ordering".
