Minute-by-minute · 80-minute block

💡 Big idea: A decision matrix makes tradeoffs visible and keeps design choices defensible.

  1. 0-5 minWarm-up: name two criteria a medical device must meet before you'd use it
  2. 5-20 minList three design options and define four weighted criteria
  3. 20-45 minScore each option; compute and double-check weighted totals
  4. 45-60 minWrite justification: winning option and deciding criterion
  5. 60-72 minPeer check: swap matrices and verify weights sum to 100
  6. 72-80 minExit ticket: one sentence on why the lowest-scoring option was eliminated
Mr. Mendoza's 5-minute intro
  • Today we replace gut instinct with math by using a weighted decision matrix.
  • You'll score three design options against criteria you set and then let the numbers guide you.
  • This is exactly how engineering teams avoid bias when choosing between prototypes.
  • By the end you'll have a justified design direction and a document to back it up.
Do this, step by step
  1. 1List three candidate design options for your prototype.
  2. 2Define four selection criteria such as cost, safety, feasibility, and effectiveness.
  3. 3Assign each criterion a weight that sums to 100 percent.
  4. 4Score each option against each criterion and compute weighted totals.
  5. 5Write a justification naming the winning option and the criterion that decided it.
You'll be able to
  • You completed a weighted matrix with at least three options and four criteria.
  • You justified your choice using the matrix results.
Know by the end
  • Criteria weights reflect what matters most to users and stakeholders.
  • A weighted score lets you compare options with different strengths objectively.
  • Documenting the matrix is a Lab SOP practice: decisions need an auditable rationale.

Open this PLTW section today

Literature review, decision matrices, validation metrics, MP1 data inflection. · Decision matrix

Day 3 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.

Do this: Open Problem 3 in your myPLTW course shell and navigate to the current activity, then build a weighted decision matrix to choose among your prototype design options.

Complete

Upload your completed decision matrix to the Problem 3 portfolio.

How far to get

The literature review is done; by end of today your weighted matrix with three options, four criteria, and a written justification should be submitted.

Upload as evidence

Photo or screenshot of your completed weighted decision matrix with justification attached as evidence.

All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.

The plan

Today's PLTW tracker

Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.

Today's PLTW target

Literature review, decision matrices, validation metrics, MP1 data inflection. · Decision matrix

Open Problem 3 in your myPLTW course shell and navigate to the current activity, then build a weighted decision matrix to choose among your prototype design options.

The literature review is done; by end of today your weighted matrix with three options, four criteria, and a written justification should be submitted.

This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.
