Contracting

Just recently I’ve been having discussions about possibly becoming a contractor for a little while and it’s thrown up a question that’s haunted me ever since I started examining other people’s computers.

I’m a fan of open-source software and I really do believe that one of the benefits I offer as a consultant is the fact that I don’t use the same examination kit as everyone else. It means that when I check their results or they check mine we are using significantly different tools, and mine are open for anyone to scrutinise at the source-code level. So, if we find a discrepancy we can dig deep into at least one the tools, if necessary, to find the reason why. It’s proper dual-tooling, or as close as we can get for now.

Now, in the past I’ve had to explain this (because there are two or three tools that everyone expects to see and eyebrows are raised when I don’t mention them ) but it has never stopped me getting an expert witness job. The critical word there is “expert” – in that role I am supposed to exercise my judgment to select the best tools and methods for the job.

However, a contractor is different creature – if I do get offered this job, I have to fit into someone else’s working environment and do things their way with their tools. I can do it. In my academic life I had to learn new skills, tools etc. very quickly and be able to teach them to other people. It’s a knack that a good lecturer picks up soon, or they don’t survive in labs. for long. The question is, will the client believe I can do it or will they wait until they find someone with the right piece of paper instead ?

My argument, for what it’s worth, is that I can learn the tool quickly and, because I have a background in computer science and am used to creating little ad-hoc tools whenever I need them, I can check the tool’s results in a way that someone who just know the program might not be able to.

We shall see.

Meanwhile, in the world of standards and regulation things have gone quiet in the Regulator’s office. His contract has been extended for another 3 years, but I rather think he’s suffering from budget cuts elsewhere. No matter, plans are well underway for the next ISO meeting in Singapore where we will be trying to get some new work approved to go beyond the current ISO/IEC 27037 and ensure we have guidance for a complete process from planning through acquisition to analysis, with proper validation all the way through.
