Welcome, everyone! Today, we're diving into the purpose of writing a design specification. Can someone tell me why collaboration might be essential in this process?
I think it helps get different perspectives, so we donβt miss important details.
Exactly! Specifications should evolve through stakeholder input. This means engaging with clients and users constantly! It's a bit like crafting a story together. Can anyone think of a scenario where a specification might need drastic changes?
If the target usersβ needs change or new technology is introduced?
Great point! Specifications should adapt to those changes. Remember the acronym 'CLEAR' β Collaboration, Listening, Evaluation, Adaptation, Review. Letβs keep this in mind!
To summarize, the specification evolves with continuous stakeholder feedback, ensuring it meets user needs effectively.
Structure of a Specification

Now, let's discuss the structure of a design specification. Who can share what components we should include?
User personas and user stories are crucial!
Correct! User personas help us understand our audience better. What about user stories? How do they enhance our specification?
They describe how users will interact with the product, which is helpful for designing solutions.
Exactly! User stories articulate real user interactions, making the product more relatable. Can anyone recall how to outline functional and non-functional requirements?
Functional are what the product must do, and non-functional address performance and security.
Perfect! Always remember: Functional = 'what,' Non-functional = 'how well.' Letβs wrap up. Specifications include user personas, user stories, requirements, wireframes, and more. Keep this structure in mind as it secures a comprehensive design process.
Hands-on Implementation

Now let's get hands-on! We'll start drafting the personas and requirements section. What do you think the personas should include?
They should have names, photos, demographics, and their goals.
Excellent! That's a well-rounded persona. And how about linking our requirements to research data?
We should include evidence to support each requirement, like survey results.
Exactly! A traceability matrix is perfect for this purpose. It ensures every requirement is backed by data. Remember, every draft is a chance to improve. Letβs explore that matrix now!
In summary, we must draft detailed personas and structured requirements, always linking them back to research data for validation.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
In this section, students learn how design specifications evolve through collaboration and stakeholder input. The comprehensive structure includes user personas, user stories, functional requirements, wireframes, and test scenarios, forming a cohesive framework for effective design.
Detailed
In the Final Design Specification section, the focus is on developing a comprehensive document that serves as the foundation for the design process. Students are encouraged to view specifications not just as a static document, but as a collaborative tool that evolves through engagement with stakeholders.
Key Points:
- Purpose & Collaborative Nature: Specifications should be seen as living documents, evolving as feedback from stakeholders is gathered. Role-playing in class helps students understand the iterative nature of this process.
- Comprehensive Structure: The specification is structured into various critical components:
- Introduction: Outlines the project's aim, background, and scope;
- User Personas: Detailed profiles of target users that highlight their motivations and challenges;
- User Stories & Use Cases: Formalized narratives describing user interactions;
- Requirements Section: It includes functional requirements (what the product must do) and non-functional requirements (performance, security, accessibility);
- Wireframes & Flow Diagrams: Visual sketches aiding in the design process;
- Test Scenarios: Detailed steps to ensure each requirement is met.
- Hands-on Implementation & Traceability Matrix: Practicing drafting specific sections of the specification, such as personas and requirements, reinforces the importance of detailed, research-driven documentation. Creating a traceability matrix further helps in aligning requirements with research data.
The section encourages students to think critically about each component of the specification and understand how meticulous documentation underlines a successful design process.
Key Concepts
-
Collaborative Nature: Specifications evolve through stakeholder input.
-
User Personas: Detailed profiles representing target users' needs and motivations.
-
Traceability Matrix: A mapping tool linking requirements with source research data.
Examples & Applications
Example of a User Persona: 'Priya, 17, juggles homework and sports, seeking better time management tools.'
Example of a Functional Requirement: 'The app must allow users to sync their calendars.'
