As requirements are being gathered and prioritized, they also need to be documented. In Diagrammatic Notations and Software Requirements Specification Writing, we discuss and practice the process of turning requirements into something readable to the customers at a high level, and the developers. When a designer or developer reads your document, they should be able to understand the overall idea, the scope, the domain, the resources, the expectations, and why alternative choices are not selected. To create a document in this way, you use a balance between storytelling (with pictures!) and complex diagrams.

Beginning to Write an SRS Document
Beginning to write a Software Requirements Specification (SRS) is a daunting process. As you start elicitation and move onward through the requirements cycle, you should plan your approach and begin writing as soon as possible. In this module, we discuss local and global rules that should be followed to lead to success.

Beginning Diagramming
Within a requirements document, you should tell a story. Pictures help in stories! In this lesson, we'll look into some of the "pictures" that you can create to clarify understanding for all readers and to help yourself know that all points are being covered clearly and completely. Specifically, we'll consider high, system-scope diagrams.

Lower-Level Diagramming
At a lower level, Entity Relationship Diagrams, Data Flow Diagrams, and SADT diagrams can be used. All three sets of diagrams work together to explain lower-level relationships and dataflow for components in the system-to-be. In this lesson, we'll discuss what these diagrams look like and what information should be included in such diagrams.

À propos de la Spécialisation Requirements Engineering: Secure Software Specifications
This specialization is intended for software engineers, development and product managers, testers, QA analysts, product analysts, tech writers, and security engineers. Even if you have experience in the requirements realm, this course will expand your knowledge to include new viewpoints, development styles, techniques and tools.
For anyone seeking a graduate degree, certificate, or professional degree in computer science, these courses will additionally give you a broad understanding of how requirements engineering is performed and help you get a first foot forward into your upcoming careers.
The Software Requirements specialization focuses on traditional software requirements elicitation and writing techniques, while also looking at requirements from a security standpoint. In traditional methods, non-functional requirements, such as security, are often ignored overall. In this specialization, students will be introduced to ways of eliciting requirements from stakeholders, how to analyze these requirements, conduct risk mitigation and analysis, prioritize requirements, document, and bring security concerns into the software lifecycle early on.
