Requirements Validation and Testing
Course Description
Quality is the major business differentiator in IT. Studies such as the Chaos Report show that the most common cause of low quality is having poor, or poorly understood, requirements. Other common causes are poor design, code, and installation. While prevention of defects is the best cure, identifying and fixing defects as early as possible is key, and some of the responsibility for doing that falls on the business analyst (BA). This course, therefore, concentrates on the validation techniques for:
- Requirements
- The system at the business level (functional and usability testing)
- Acceptance
- Business purpose (stakeholder satisfaction with the production product)
In this course you will learn the importance of achieving quality and your role in doing so. You will learn which project and product factors affect the two components of risk (likelihood and impact), and you’ll learn to apply those to various real-life validation situations using a case study and practicing testing decision-making. You will learn techniques for:
- Validating requirements or any text-based product (such as procedures or plans)
- Testing functional and manual requirements
- Assessing and testing usability
You will learn to plan functional and usability testing at the business level and the essential elements to document that planning. You’ll examine your role in Acceptance, including Acceptance of an outsourced product, and you’ll determine how to assess stakeholder satisfaction with the product in production.
Since there is never time, even theoretically, to validate all details of a product, an important concept is using risk assessment to determine the appropriate thoroughness of validation at every stage. Exercises in risk assessment and all the major validation techniques are an integral part of this course.
While the involvement of BAs in testing varies widely across companies, this course assumes maximum involvement at the business level (excluding nonfunctional testing except for usability). Each student can tailor the content to suit a specific company’s policies.
Students pursuing a university-recognized and/or accredited certificate in Canada or continuing education units in the US must attend at least 90% of class time, participate in class exercises and section-knowledge checks, and score at least 70% on an end-of-class, multiple-choice assessment.
Highlights
- Position the activities of the BA in the complete verification and validation process
- Use testing terminology in a standardized way
- Use risk to drive the validation effort and therefore use project money wisely
- Make decisions on what not to test for defects
- Plan appropriate (risk-based) techniques to find defects in the BRD, that is, validate the BRD
- Plan appropriate (risk-based) functional testing techniques at the BA level to find defects
- Plan appropriate (risk based) glass box testing techniques for processes to find defects
- Check and test usability
- Choose appropriate (customer-selected) tests for acceptance, that is, compliance to requirements
- Manage test data and information
- Manage requirements problems and test failures
- Document the plans (activities, resources, risks)
- Gain acceptance, install the product, and validate to business needs
