Requirements Analysis Techniques

Download PDFRequirements analysis is the process of breaking down complex topics into lower-level components to expose the details and gain a better understanding of the parts that make up the whole. By breaking it down and using effective requirements analysis techniques, you are better able to analyze and discuss different aspects of a topic with your stakeholders, confirm your understanding, and communicate the needs to others in a more logical and thorough manner. Team members need to look at the requirements from different perspectives as well as with varying levels of detail, therefore it’s critical to have strong requirements analysis skills within the team.

Poor requirements analysis results in solving the wrong problem, missing requirements, or ineffective communication with critical stakeholders. Excellent requirements analysis provides an effective communication vehicle and allows for collaboration among stakeholders to find and fill-in gaps, clarify requirements, examine alternative solutions, and ultimately develop an excellent product or solution.

Classroom Experience

Interactive workshops allow students to practice the requirements analysis techniques as they learn. It supports the standards outlined in the IIBA BABOK® Guide and PMI-PBA certification. This course can be taken either stand-alone or as part of the 4-day Essential Skills for Business Analysis course.

Learning Objectives

  • Simplify your requirements into four core components that are easier to “consume”
  • Still writing requirements? Instead, identify the most effective diagramming techniques and modeling options to support your software development approach (waterfall, iterative, and agile) and project type
  • Compare analysis techniques to select the technique(s) that will best:
    • support your critical thinking, understanding, and problem solving
    • communicate to stakeholders information to enhance review
  • Minimize confusion and development errors by developing excellent requirements that can be easily understood by distributed or outsourced teams
  • Improve your models and diagrams during analysis by asking the right questions

4 reviews for Requirements Analysis Techniques

  1. :

    Excellent and well organized. I wasn’t sure how smoothly things would go with a virtual training, but it felt just like being in a classroom.

  2. :

    Excellent exposure to a variety of tools that can be tailored to fit some of my company’s unusual methods of reaching development and release goals.

  3. :

    Instructor did a great job of covering a larger variety of different requirements analysis techniques. She was particularly adept in breaking down complex ideas into easy to understand components. She provided great examples.

  4. :

    I really enjoyed the class! There was plenty of interactive exercises to apply what we learned during the lectures.
