POE Unit 1 • Lesson 1.13

Research, Criteria, Constraints, and Decision Matrix

Use research and a decision matrix to compare possible aerospace mechanism concepts.

Lesson Snapshot

Student Objective

I can research mechanism options and use a decision matrix to justify a concept direction.

Main Activity

Research similar mechanisms, generate comparison criteria, and score early concepts using a decision matrix.

Deliverable

Research notes and decision matrix

Tools / Materials

Notebook, decision matrix template, course resources, VEX kit for concept testing

1ProblemUnderstand the challenge and why it matters.

Teams often jump to the first idea that seems possible. Engineers need to compare options against the actual criteria and constraints before committing to a design direction.

2ConceptLearn the engineering idea or skill.

A decision matrix helps teams compare concepts using weighted criteria. Research helps identify proven approaches, failure risks, and useful design features before building.

3ApplyUse the skill in a guided task.

Collect examples of mechanisms that could solve your task. Generate at least three concept options, choose criteria, and score each concept in a decision matrix.

4DocumentRecord your evidence and decisions.

Submit research notes with sources or example descriptions, a completed decision matrix, and a written justification for the selected concept.

5ReviewCheck quality and identify your next step.

A strong matrix uses criteria connected to the challenge, not generic categories. Your selected concept should make sense based on the scores and explanation.
