Testing times

In aerospace and defence, the inherent complexity of devices and organisations increases the chance that test system development will not proceed in a linear fashion. Somewhere along the way, technical and business requirements will change and so will the unit under test (UUT). Applying the right expertise at each stage of a well structured development process will help you keep things on track.
Everything lives in the shadow of ‘The Program’. The unenlightened boss may have a view of how things will go:
* The UUT is well understood, clearly defined and fully specified
* There are sufficient resources – funding, staff and equipment – to complete the task
* The schedule is more than adequate and there is plenty of time to complete every required task and deliverable
* You can easily create a clean test system on the first try, on time and within budget
* At the end of the project, everyone will be happy.
Once the project gets underway, the unenlightened boss and the experienced engineers all ponder the same question – ‘who gets blamed if something goes wrong?’.
Those who have been ‘around the block’ a few times understand one key point – in the absence of a plan, more things are likely to go wrong than right. A good process – plus the right expertise at each step – can bring fantasy closer to reality.
