User stories
Instruction
Requirements are based on a user story, which is is an informal, natural language description of one or more features of a software system. User stories are often written from the perspective of an end user or user of a system. Depending on the community, user stories may be written by various stakeholders including clients, users, managers or development team members. They facilitate sensemaking and communication, that is, they help software teams organize their understanding of the system and its context. Please do not confuse user story with system requirements. A user story is an informal description of a feature; a requirement is a formal description of need (See section later).
User stories may follow one of several formats or templates. The most common would be:
"As a <role>, I want <capability> so that <receive benefit>"
"In order to <receive benefit> as a <role>, I want <goal/desire>"
"As <persona>, I want <what?> so that <why?>" where a persona is a fictional stakeholder (e.g. user). A persona may include a name, picture; characteristics, behaviours, attitudes, and a goal which the product should help them achieve.
Example:
“As provider of the Climate gateway I want to empower researchers from academia to interact with datasets stored in the Climate Catalogue, and bring their own applications to analyse this data on remote cloud servers offered via EGI.”
No. | User stories |
|---|---|
US1 | As a user I want to be able to run jobs and workflows on cloud-based resources |
US2 | As a user I want my jobs/workflows to transparently burst onto external cloud resources, such as EGI FedCloud or a public cloud, when my local resources are at capacity |
US3 | As a user I want my jobs/workflows to run anywhere without having to worry about software dependencies |
| US4 | As a user I want to be able to access the output data from jobs/workflows through a dropbox like solution |
| US5 | As a user I want to be able to access both computing and storage resources with the same credentials |
| US6 | As a user I want to be able to access fusion data via UDA |
| US7 | As an experiment data manager I want data to be automatically replicated at several sites |

Use cases
Instruction
A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language as an actor) and a system to achieve a goal.
Include in this section any diagrams that could facilitate the understanding of the use cases and their relationships.
