POE Unit 2 • Lesson 2.16

Concept Development, Decision Matrix, and Build Plan

Sketch multiple payload support concepts, compare them using a decision matrix, and create a safe build and test plan.

Lesson Snapshot

Student Objective

I can generate multiple structure concepts and use evidence to select a design direction.

Main Activity

Sketch multiple payload support concepts, compare them using a decision matrix, and create a safe build and test plan.

Deliverable

Concept sketches, decision matrix, and build plan

Tools / Materials

Graph paper, decision matrix template, approved materials list, ruler

1ProblemUnderstand the challenge and why it matters.

Teams often want to build the first idea they like. Engineering teams compare alternatives before committing to a design direction.

2ConceptLearn the engineering idea or skill.

Concept generation, decision matrices, and build planning help teams justify a design with evidence. Strong plans include material choices, member layout, joints, tools, safety steps, and test preparation.

3ApplyUse the skill in a guided task.

Generate multiple structural concepts, score them against criteria, and select one design to build or prototype.

4DocumentRecord your evidence and decisions.

Submit concept sketches, a decision matrix, and a build plan that includes materials, tools, dimensions, and safety notes.

5ReviewCheck quality and identify your next step.

Your selected concept should be the best-supported design, not simply the easiest drawing or the most familiar shape.
