What Requirements Are

CNM Cyber suites

What Requirements Are (hereinafter, the Lectio) is the lesson part of the Digital Transformations lesson that introduces its participants to the development of CNM Cyber. This lesson belongs to the Introduction to CNM Cyber session of the CNM Cyber Orientation.

Content

The predecessor lectio is What the DevOps Is.

Script

The requirements the documents that 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 or specific 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.

Having a variety of documents may create some confusions if some documents contradict each other. The concept of single source of truth (SSOT) aims to solve that challenge. Product epics are drafted at CNM Wiki, but their approved versions are published at CNM Page.
