Key terms

Requirement. An expressed demand, desire, expectation, and/or wish to have or not to have a certain product and/or a certain capability, condition, feature, and/or property. The plural term, requirements, may refer to the aggregate of various requirements that the product owner or another authority for the requested product and/or its development process has approved, verified, and/or validated.

• Product epic. A detailed description of a proposed product that is designed to make its potential consumer understand what this product shall do. At CNM Cyber, the Epic is any wikipage that describes a desired product.
• User story. A brief description of a solution requirement to a desired system that is written from the point of view of a customer or end-user of this system. In other words, the story is a high-level, informal, brief, non-technical description of a solution capability that provides value to its stakeholder. The story is typically one or two sentences long and provides the minimum information necessary to allow a developer to estimate the work required to implement it. In order to ..., as a ..., I need to ... or, using another format, In order to [achieve some goal], as a [type of user], I need to [perform some task or execute some function] is a generic example of the story.

Requirements specification. A requirement in a form of technical description of a proposed system.

• CNM Cyber requirements. The requirements specification for CNM Cyber.
• CNM Cloud requirements. The requirements specification for CNM Cloud.

Script

The requirements represent the visions of what needs to be developed. Creation of requirements is neither an easy nor straightforward process.

Initially, the CNM Cyber Team creates product epics. At CNM Cyber, they are the wikipages that describe the new deliverables that need to be developed. The product epics' category lists of the available epics.

These product epics are helpful to clarify the vision of new deliverables, but they are rarely clear for developers to implement and not useful for the CNM Cyber Team to accept developers' work.

To make the epics usable for the product developers, these epics are chunked in user stories. Every story represents one function or feature and is written from the point of view of an end-user. To create the stories, the CNM Cyber Team uses a simple format, In order to ..., as a ..., I need to .... For instance, In order to develop user stories, as the CNM Cyber Team member, I need to know their format.

For the developers, these stories indicate what needs to be developed. More thorough requirements specifications indicate the rest what the developers need to know. Those specifications include what rules and regulations exist, how the developers shall submit their works, etc. At CNM Cyber, one specification, CNM Cyber requirements, clarifies the overall requirements for the CNM Cyber development, while another, CNM Cloud requirements, does so for the CNM Cloud one.

All of those requirements are created at CNM Wiki to be open to the general public. This policy serves two purposes.

First, the CNM Cyber Team can solicit better feedback in that way.

Second, even pre-entry-level developers can see the complete development process 24 hours a day and 7 days a week.
