Ultimate Requirements Assessment Tutorial Part 1

This is the first of three presentations concerning assessing the quality of poorly formed requirements based on the characteristics and rules defined in the INCOSE RWG Guide to Writing Requirements (GtWR). The three presentations are divided into shorter presentations suitable for viewing during a lunch and learn session or a training session offered by an organization. The three presentations were created by Lou Wheatcraft, CoChair of the INCOSE Requirements Working Group (RWG). While there is a separate presentation providing an overview of the GtWR and a more in-depth presentation on the rules for writing well-formed need and requirement statements, these three presentations apply the rules to a case study helping to ensure they are well-formed. Learning is enhanced when theory is applied to an actual real-world system to be developed. The case study involves developing a well-formed set of system level design input requirements for a Lid Installation Robot (LIR) whose function (intended use) is to install lids on jars. In the first presentation, an overview is given of the characteristics and rules discussed in the GtWR that contribute to well-formed requirements and a well-formed set of requirements followed by an overview of the case study in-order to understand the context of system of interest (SOI) - the LIR. When defining, as well as assessing the quality of, a set of requirements, it is critical to understand the context in which the SOI exists as well as the level of requirements being defined. After the overview, individual poorly-formed requirements are presented, followed by an assessment of those requirements using the GtWR characteristics and rules as a measure of quality, and then an improved version of each requirements is presented. I say "improved", because there may be something that was overlooked as well as there is often more than one way to communicate a well-formed requirement statement. For the cases where these presentations are viewed in a group/class setting, there is a pause after each poorly formed requirement is presented to allow the recording to be paused and then a group discussion to take place concerning their assessment of the defects. The recording can then be resumed to view an assessment of the requirement followed by another pause where the recording can again be paused to allow for another group discussion on the defects that were discussed. Before resuming the recording, it would be instructive for the members of the group to formulate their own improved version of the poorly formed requirement. The recording can be resumed to view the presentation of an improved version of the requirement. In many cases, in order to meet the intent of the poorly formed requirement, the improved result is communicated as multiple well-formed requirements. Again, the recording can be paused to allow the group to discuss the improved requirement(s) and compare with their improved version of the poorly formed requirement. Parts 2 and 3 are a continuation of the poorly-formed requirements that are assessed and improved versions presented.
