Learning Objectives
By the end of this lab, you should clearly understand:
Measurement drives decisions
Good systems can behave badly due to bad measurement
Many real-world problems start with incorrect information, not faulty equipment
Engineers must question data before acting
🧭 How to Use This Lab: Why Measurement Matters
This lab helps you experience why measurement is critical in engineering systems — without theory, formulas, or calculations.
Follow the steps below in order.
Step 1: Observe the Process
Look at the physical process shown (e.g., tank level or temperature).
Notice how the process behaves before any decision is made.
At this stage, do not change anything — just observe.
👉 Goal: Understand the real condition of the process.
Step 2: Watch the Measurement
Focus on the measurement indicator linked to the process.
Observe how the system “sees” the process through measurement.
Notice that decisions are based on measurement, not direct reality.
👉 Key insight: Engineers act on what is measured, not what actually exists.
Step 3: Change the Process
Use the provided control (slider or button) to change the process condition.
Observe:
how the process changes
how the measurement responds
👉 Ask yourself:
“Did the system react because the process changed, or because the measurement changed?”
Step 4: Introduce a Measurement Issue (If Available)
Enable options like:
noisy measurement
delayed measurement
wrong measurement
Keep the process stable while changing only the measurement.
👉 Critical realization:
A healthy process can look problematic if the measurement is misleading.
Step 5: Observe the Decision & Action
Watch how the decision block or action element responds.
Notice that:
correct actions on wrong data still cause problems
wrong decisions are often logical when based on bad measurement
👉 Key lesson:
Wrong measurement → wrong decision → wrong action.
Step 6: Use the Reflection Prompts
Answer the reflection questions shown in the lab, such as:
“Is the problem in the process or the measurement?”
“Would this mislead an operator?”
“What would you question first in real life?”
There are no right or wrong answers.
👉 Purpose: Build engineering judgment, not memorization.
Step 7: Reset and Try Again
Reset the lab.
Try different combinations:
stable process + bad measurement
changing process + good measurement
Observe how conclusions change.
👉 Learning happens through comparison.
