The document discusses a workshop on using CKAN for research data management. It provides examples of requirements formatted as user stories, with "As a user, I want to do X, so that I can achieve Y". The document also discusses constraints that may affect the design like resourcing, existing technology decisions, and social constraints. Participants were divided into user types to create wish lists and requirements were said to evolve through negotiation and clarification during development.

- 1. CKAN for Research Data Management Workshop, London, 18th February 2013 Joss Winn, University of Lincoln http://orbital.blogs.lincoln.ac.uk
- 2. ¡°There are no such things as requirements, there are only wishes.¡± Kent Beck, 2000. Requirements = wishes Let¡¯s split into different types of users and create wish lists. If you like, you can be a ¡®proxy user¡¯, taking on the role of someone else.
- 3. Essential components of a requirement ? What should the required function/feature do? ? Who is intended to use it? ? How does it provide value? ? What major constraints affect the design? Requirements evolve through negotiation and as further clarification is provided during development. Today, we¡¯re going to create ¡®stories¡¯ that can be returned to at a later date. Taken from Cockburn(2005) Crystal Clear. A Human powered Methodology for Small Teams
- 4. Examples Format: As a X user, I want to X, so that X e.g. Who, what, why? ¡°As a Publisher I want to Archive resources so that old or out of date resources can be hidden¡±* ¡°As a User I want to Browse and search for other users so that I know about others active on the site¡± * Go here for actual requirements from workshop: http://lncn.eu/mxz2 * Taken from the (old) CKAN wiki list of user stories
- 5. The Constraints ¡°What major constraints affect the design?¡± ? Resourcing: ¡°That would take four developers 6 months to implement¡± < Break it down! ? Existing design/technology decisions: ¡°The software is designed for the web, not a desktop application.¡± < Can desktop apps be written to use the web APIs? ? Social constraints: ¡°Most of our existing users would find that feature confusing/irrelevant.¡± < Create an extension for esoteric features.
- 6. Creating Use Cases Can we group our requirements into use cases? How do certain requirements relate to one another? e.g. ? Data store requirements ? Data repository requirements ? Data catalogue requirements Example use case: http://j.mp/Y6uWvD
