5. jgs Requirements
6. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 6 Epic – Too Complex or Big or no INVEST Functional Requirement Story (Product or Sprint) Backlog Item INVEST 100% Task – Too Easy or Too Small (or trivial technical labor)
7. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 7 a) May state what (reactions, behaviours, or services) the system should not do. b) services the system should provide, c) how the system should react to particular inputs, and d) how the system should behave in particular situations. Functional Requirement
8. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 8 Analogy Chapters Sections Paragraphs or Sentences
9. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 9 § Independent – loosely coupled with one another § Negotiable – Stories are what and why , not how ( 99% ). § Valuable – for the customer! § Estimatable – Effort/Cost of design, build, and test. § Small (sized appropriately) § Testable – pass or fail INVEST in good requirements
10. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 10 § Can someone do this and integrate it later into the main project? § Do we all understand what this is? § Is this important for the customer? § Can we estimate the cost of this (complexity, LOC, effort, or time)? § Is this appropriate for a Sprint (period of time)? § Do we know how to test it and prove it is complete? INVEST in good requirements
11. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 11 Task board … move the pacman … show the pacman … move a ghost … show a ghost … show power pills stories tasks (new) … show a maze
12. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 12 Note We will talk about Quality later i.e., Non-Functional Requirements
13. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2024 | 13 § Search option given to user to search from various invoices. § User should be able to mail any report to management. § Users can be divided into groups and groups can be given separate rights. Examples What about • A video game? • Canvas? • Facebook App?
