Study Notes
Class #4 - Requirements Documentation
- This class covered the importance of documentation for software, specifically requirements documentation.
- The question of whether working software negates the need for documentation was raised and addressed.
- Documentation is crucial for team understanding, preventing scope creep, and guiding developers.
Why Document?
- Good documentation ensures understanding across teams.
- It avoids scope creep and helps developers work together.
- Principles of requirements documentation include clarity, specificity to avoid misinterpretations, testability and measurability for non-functional requirements, consistency and conciseness ensuring precise and to the point information.
SRS Documentation (Software Requirements Specifications) - Functional vs Non-Functional
- Functional Requirements: Describe specific functions and behaviors the software should perform. -Examples include login functionality, order processing, search capability. -Tested by functional testing to ensure it works as specified.
- Non-Functional Requirements: Describe quality and performance characteristics. -Examples include performance metrics, security standards, and scalability. -Tested by performance, security, and usability testing to check if they meet quality standards. -Examples include speed, security standards, uptime, scalability.
Example SRS Document (Example)
- Specific example scenarios of functional and non-functional requirements were included for different features of the software.
- Login System: The login page should load in 1 second, search results within 2 seconds.
- Product Search : Users can search for products by name, category, or price.
- Payment Processing: The system must process payments through a secure gateway and comply with standards.
- Order Tracking: Users can track orders within 5 minutes of status changes.
Example Use Case Diagram
- A use case diagram visualizes different actors and their interactions with the system.
- Prospective Customers, Customers, Procurement Managers, Service Representatives, and Meal Managers are examples of actors.
- The use case diagram depicts the interactions within the Online Ordering system.
Use Cases
- Actors: Individuals or systems interacting with the system.
- Description: Summary of the use case's goal.
- Preconditions: Prerequisites before the use case starts.
- Basic flow: Step-by-step description of critical interactions.
- Alternative flows: Alternative paths from the basic flow.
- Dependencies: Related use cases, systems, or modules required.
User Story
- A user story captures what a user does or needs as part of their work.
- Details may not be as detailed as a use case.
- User stories leave out important details to be discussed during sprint meetings.
How to Write a User Story
- Structure: "As a [persona], I want [goal] so that [benefit]."
- Acceptance criteria: (Conditions of satisfaction). Example of using this format in creating a user story.
User Story 3Cs
- Card (concise and easy to understand).
- Conversation (crucial for clarification).
- Confirmation (Acceptance criteria).
Acceptance Criteria
- Defines the scope, desired outcomes, and testing criteria for functionality.
- Enables communication and agreement between developers and the product.
Example Acceptance Criteria
- Acceptance criteria follow a format of (Given), (When), and (Then) clauses.
INVEST
- Independent : A good story can be worked on separately.
- Negotiable: Acceptance criteria must be negotiable.
- Valuable: Delivering value is necessary.
- Estimable: Understand the size of the work.
- Small: The amount of work should be small.
- Testable: Can the work be measured?
Story Slicing Phases
- Phase 1: Focus on the user and the goal.
- Phase 2: Gather details on implementation.
Story Mapping with Personas
- Visual representation of user stories grouped around user goals
Martha's Story
- Example of a user story: Martha wants to buy pizza with friends but doesn't have cash.
Visual Story Slicing Example
- Diagram depicting interactions and steps in the pizza purchase process.
Don't Get Distracted by "Plumbing"
- Focus on core functionality first.
- Separate requirements from supportive or non-functional ones.
- Maintaining maintainability, Security, Scalability and Logging are non-functional requirements.
- Initially, these needs may be addressed in further iterations.
Indicators of Poor User Stories
- Issues with stories during sprint planning, refine and backlog.
- Lots of questions during sprints.
- Excessive rework or bugs.
- Consistently missed commitments.
- Product owner surprise during reviews.
