ReqIf – standardising interchange?

Just to drop a few quick lines on the side of this article from the most recent IREB Magazine issue: Open Up. The leading Automotive companies (both OEMs and suppliers) already picked up the lead in developing an open requirements exchange standard. And maybe this is the most important word here: standard. They are the most affected, so with a great interest in aligning exchange. Then my thoughts: how about open source requirements management tools? There are already some, but any chance soon any of them could emerge above all and replace the established ones, DOORS for instance? Especially...

A Quick Peek Over a Day in Our Life

To start with a statement, a clear view of: the System Engineer is the one who is leading the entire projects technical development, therefore standing side by side with the project leader, complementing him. So, the Systems Engineer becomes a point of convergence of the various expert’s opinions, recommendations and interests. All only seeing chunks of the entire problem, and trying to impose their perceived best solution. Here comes the Systems Engineer’s role in comprising the problem in it’s entire complexity as a whole, assuring that different pieces are still...

What’s a System Engineer

There is still an active discussion of what System Engineering and the system engineer is all about. I found a very interesting post on the matter here. The historical roots have created some of the differences in these definitions of “systems engineering.” For example, the INCOSE definition comes from its roots in electrical engineering and its early application in places like Bell Labs, the defense industry, and space programs.[1] All systems engineering definitions and all industrial engineering programs share a focus on a set of methods and techniques, although the particular methods and...

Distinguishing Between Requirements and Specification

I often hear the term specification used for referring requirements… Some organizations try to produce a single specification to act as both a requirements definition and a requirements specification. When a requirements definition is combined with a specification there is often confusion between concepts and details. There’s no really clear distinction in it’s usage, though the difference is really simple. Then, what are requirements and specification? If you look on the Project Performance International site, the difference is explained in a very simple manner:...

About Requirements and Design

Let us be clear from the start what requirements mean. Are they the description of the system to be? At first glance yes, even though that is only half of the truth: they are the description of what the system should be doing, and what is the fashion it should behave or look like. But they are not the description of how that behavior is accomplished. If you are looking at the implementation of a required (in other words requested, desired) behavior, you are looking at design. Because that’s what requirements are all about: the what. Requirements specify WHAT a system (entity) should be...
