Development Cycle, Reviews, and Deliverables Flashcards
Stage-Gate Model
Used to represents the development cycle of a product
‘Stage’ - No different than a phase
- Represented by rectangles
‘Gate’ - Usually a “Technical Review” or test where you have to show your work and justify your design decisions
- Represented by triangles
The idea is that you do some work, pause and check to make sure to was done right and that you are on the right track, then continue the project.
In order to pass on to each stage, you need to meet the criteria of the gate
Each gate has one of four outcomes
1) Go: means the project continues as planned
2) Hold: Basically purgatory, you’re not ready to ‘go’ but the project hasn’t
3) Recycle:
4) Kill: The project is over

Importance of the ‘gates’ and periodic reviews
Helps you catch problems earlier
No different than going to the doctor to make sure that your health is good and that there’s nothing about your diet/lifestyle you need to change
Importance of continuously revisiting the purpose
Helps prevent you from diverging from what you set out to do (or what the customer asked you to do)
- This helps prevents mistakes when it comes to system validation
Two main things that can blow up the costs for a project
1) Diverging from the actual purpose of the project (if you don’t catch it early, it could be very expensive to get it back on track… that’s why you constantly compare the implications to the purpose)
2) Small problems early in the design that don’t get discovered until testing (can cause you to basically startover)
System Thinking attitude towards iteration and recursion
Iteration is possible in ALL phases of the design
Technical Reviews
A formal Presentation where have to show your work and justify your design decisions
- Represented by triangles on the
- Commonly Referred to as ‘Gates’
- Technical Reviews always come with artifacts that you need to have ready for the presentation
“Horseblanket”
Refers to the visual representation of the schedule in the form of a gate-stage model:
- Stages represented as rectangles
- Gates represented as triangles
*Can sometimes have multiple layers, like a Gantt chart
