Answers for Certified Software Quality Engineering Quiz #5

1. Answer B is correct.  The ISO/EIA/IEEE 12207 standard establishes a common framework for software life cycle processes.  IEEE Std 730 establishes minimum acceptable requirements for the preparation and contents of Software Quality Assurance plans.  ISO 9001 establishes the requirements for quality management systems.  SEI CMMI® establishes a roadmap for process maturity.  Reference: The Certified Software Quality Engineering Handbook 2nd Edition by Linda Westfall – page 21 or The Certified Software Quality Engineering Handbook by Linda Westfall – page 20.

2. Answer C is correct.  Processes define the mechanics of what is required to implement an activity.  A process is a definable, repeatable, measurable sequence of tasks used to produce a quality product.  Policies define the over-all direction and principles to be followed when making decisions and performing activities. Plans define the specifics for how a project intends to implement the work including specific activities, responsibilities, resource and budget allocations, tactics, tools and methods.  While processes define the “what to do” requirements, the “how to do it” should be left to the lower level work instructions.  Reference: The Certified Software Quality Engineering Handbook 2nd Edition by Linda Westfall – page 78 or The Certified Software Quality Engineering Handbook by Linda Westfall – page 64. CSQE Body of Knowledge Area: II.A.1

3. Answer B is correct.  The purpose of a firewall is to limit unauthorized access to the system, which is a security consideration.  Reference: The Certified Software Quality Engineering Handbook 2nd Edition by Linda Westfall – pages 208-209 or The Certified Software Quality Engineering Handbook by Linda Westfall – page 200. CSQE Body of Knowledge Area: III.C.5

4. Answer B is correct.  Hazard Analysis should be preformed on safety risks that involve personal injury or property damage.  Reference: The Certified Software Quality Engineering Handbook 2nd Edition by Linda Westfall – page 357 or The Certified Software Quality Engineering Handbook by Linda Westfall – pages 302-303. CSQE Body of Knowledge Area: IV.C.3

5. Answer D is correct.  Pareto Analysis is the process of ranking problems or categories based on their frequency of occurrence or the size of their impact in order to determine which of many possible opportunities to pursue first.  Reference: The Certified Software Quality Engineering Handbook 2nd Edition by Linda Westfall – page 428-429 or The Certified Software Quality Engineering Handbook by Linda Westfall – pages 369-370. CSQE Body of Knowledge Area: V.B.2

6. Answer D is correct.  There are 4 valid equivalence classes, one for each of the possible valid values and one invalid equivalence class for all other possible values.  Reference:The Certified Software Quality Engineering Handbook 2nd Edition by Linda Westfall – pages 472-473 or The Certified Software Quality Engineering Handbook by Linda Westfall – pages 406-407. CSQE Body of Knowledge Area: VI.B.3

7. Answer D is correct.  The Production baseline, also called the Product baseline, includes the configuration item, its components, units and associated documentation during the production, operations, servicing and maintenance parts of its lifecycle.  The product baseline describes the product as it is delivered to the users.  One of the key characteristics of the product baseline is that changes can only be made through a formal change process.  Reference: The Certified Software Quality Engineering Handbook 2nd Edition by Linda Westfall – pages 781-783 or The Certified Software Quality Engineering Handbook by Linda Westfall – pages 511-513.
