Week 16 Guide: Complex Concept Development

24-week programme, Project 2 Phase.

Learning goal: develop a concept that satisfies competing constraints, comparing real alternatives against your strategy and recording the rationale.
Estimated study time: 3 hours.
Evidence to upload: two or three developed alternatives compared against your criteria, your chosen direction with rationale, and the advanced iteration template.

The Real Problem This Solves

A simple problem has one good answer. A complex one has several partial answers, each strong in a different way. This week you develop real alternatives, compare them against the strategy you set in Week 15, and choose with a rationale you can defend. This is where design judgement is built.

Running projects. Develop your Project 2 concept against your design principles and competing constraints.

Key Ideas You Need First

1. Develop alternatives, do not marry the first

Take two or three genuinely different directions far enough to compare fairly. A complex problem deserves more than one worked option.

2. Compare against criteria, keep the rationale

Score each alternative against your Week 15 principles and constraints. Record why the winner won and why the others lost, so the decision is traceable.

3. Iterate the concept before you prototype

Complex concepts usually need a round of paper iteration to resolve tensions before a physical prototype.

Tools And Materials Needed

Your Week 15 strategy and principles.
The Advanced Iteration Template.
Sketching materials or a design tool.

Step-By-Step Walkthrough

Develop two or three alternatives far enough that each could work.
Score each against your principles and constraints. Note strengths and weaknesses honestly.
Choose a direction, or combine the best parts, and write the rationale.
Run one paper iteration to resolve the biggest remaining tension.
Record the round on the advanced iteration template.

Demonstrated Example

Alternatives for the shared desk: A, two stacked lift-out trays; B, a split roll-up mat with a line down the middle; C, a shared rail with two clip-on caddies.

Scored against principles: A stores too much and is slow; B gives each user a visible half and a fast partial reset; C is fast but needs a fixing the landlord refuses.

Chosen: B, with one clip-on pocket borrowed from C for oversized tools.

Paper iteration: added a stiff centre line so each half rolls independently, resolving the reset tension.

Why this is strong: real alternatives were compared against the strategy, the choice combined the best parts, and the rationale is recorded.

Architecture and spatial track version. Develop two or three plan options that switch between the quiet and noisy uses, score them against your principles, and iterate the layout to resolve the biggest conflict, for example sound versus daylight.

Your Task This Week

Develop two or three alternatives and score them against your strategy.
Choose or combine, and write the rationale.
Run one paper iteration and record it.

Submission Checklist

Upload item	Pass standard
Compared alternatives	Two or three developed options scored against criteria.
Chosen direction and rationale	Traceable to principles and constraints.
Advanced iteration template	One resolving iteration recorded.

Assessment And Pass Criteria

More than one alternative was genuinely developed.
Selection used the Week 15 strategy, with a recorded rationale.
At least one iteration resolved a real tension.

Common Mistakes

Developing one option. A complex problem needs alternatives to compare.
Choosing without criteria. Score against your strategy.
No rationale. If you cannot say why, you cannot defend it later.

Extension Challenge

Take the losing alternative and name one idea in it worth rescuing into the winner.

When To Ask For Tutor Help

Book a tutor check-in if your alternatives are really one idea in disguise, or if two options score equally and you cannot break the tie. Bring your scored comparison.
