Case Study

As the next step, we will focus on building up a case study/example. In the telco on July 25th, 2014, we decided that the case study shall involve software and hardware, and we narrowed it down to the following three:

  1. Coffee Maker: A long-time favorite, and there are at least three available (see "Case Study Examples" below)
  2. FAA Isolette: This is a complete example from a safety-critical domain.
  3. Rover: This one is driven by Gaël Blondelle from the Eclipse Foundation. On the plus side, it's great for the classroom, as the hardware is cheap. But in contrast to the others, there is nothing there yet.


The table below serves to compare possible case studies against objectives of an RE (Requirements engineering) education/course/training. Note that at this moment the list of objectives is only a proposal, adding or editing the list is welcome.

For better understanding of this proposal, a tiny bit of the RE theory adhered to:

RE consists of the activities of [1]:

  • RD – Requirements development: elicitation, analysis, modelling, specification (documenting), verification
  • RM – Requirements management: tracing, communication, reviewing, feedback processing, attributes management, change management, reporting, reuse.

The objectives of a comprehensive RE training is to illuminate all these activities more or less, but there are also other objectives, in the table bellow divided into "Requirements process" and "Requirements technology"; at the bottom, some practicality objectives too (as size of the case study).

The columns show the Relevance of the objective, as rated by various stakeholders.

The objectives, where applicable, are related to the following two authoritative RE skill overviews:

  • SI.m.n are subprocesses of the Software Implementation (SI) process as referred to in "DP-Software Requirements Analysis-V1_2.doc" on [2]
  • EU are Education Units as referred to in the IREB-CPRE Foundation Level syllabus [3]

--- Notes: ---

  • Topics should be aligned with the ISO 29110 Profiles (Entry, Basic, Intermediate, Advanced). The initial Training cursus should be targeted at the Basic Profile.

Backup

During the initial discussions, two things became clear:

  • RM&E cannot be taught without taking the wider systems engineering (SE) context into account. In other words, RM&E must be considered a subdiscipline of SE, and must be treated that way.
  • A tool must follow the process/methodology, not the other way around. Therefore, the foundation for this effort must be a solid, leightweight SE develpment process that is appropriate for teaching and relevant in practice.

Ideas

  • Examples, Exercises, etc. (Herrmann) (example customer requirements specification, exercises and sample solutions)
  • Create a mind map, to understand the problem we're trying to solve (Daniel Gross)
  • use REQB-Syllabus as a starting point
  • alternately, use the International Requirements Engineering Board (IREB) Foundation Level RE Training Syllabus
