Plan-Do-Check-Act A practice example for Deming Cycle |
| PLAN |
| Identify The Problem: |
| A digital
circuit design task |
| Select the problem to be analyzed: |
| Design 7- segment light logical circuit |
| Clearly define the problem and establish a precise problem statement: |
| Design a digital circuit to control 7-segment lights to display number from 0 to 9 |
| List the steps in the process as it currently exists: |
| 1.
Draw True tables for each 7-segment lights 2. The logic is mapped into Karnaugh maps to obtain minimized logic for each segment 3. Additional logic, such as blanking or lamp test inputs, can be added afterwards |
| DO |
| Implement a Solution |
| Draw
logic circuit according to logical expression |
| Implement the
chosen solution on a trial |
| Fix
conponents of AND, OR or XOR gates on circuit |
| CHECK |
| Evaluate The Results |
| Turn
on the circult and input data |
| Gather data on the solution |
| Check
if the result is correct as design's goal |
| ACT |
|
Standardize The Solution (and Capitalize on New Opportunities) |
| Adopt the solution |
| Look for another improvement opportunity |
