Measure software quality with 1 to 5 SIG stars

SIG has designed the SIG 5-star classification system for software quality, based on the ISO/IEC 25010 model.

Want to make your business faster, cheaper and more reliable? 

Everyone wants to offer their customers better service, optimise business processes and reduce costs etc. That’s why the software your company uses also has to perform better – be faster, cheaper and more reliable. It should be easy to maintain and configured so that your organisation can respond rapidly to changes in the market and society.

SIG shows you how

SIG does not develop business software itself but we do know how it can be improved. We can do this for every type of software, for every organisation, in any language. We can identify the opportunities and limitations that your software may have. We examine the risks associated with expansion, development and maintenance. We identify all the costs involved. We test security and privacy. And we provide tangible and independent advice: how can software help your organisation to deliver more?

Is your business more complex than Toy Story?

In 1995 Steve Jobs was running Pixar, the animated film company. In a speech that is still available on YouTube, he addressed SIGGRAPH, the yearly conference of computer graphics experts, where he talked about the movie Toy Story that was about to come out.

Need software? Avoid mantras.

'Reuse before buy before build' has been a much chanted mantra in the IT industry in one form or another. At first glance, it seems to make perfect sense and maybe even stating the obvious. The problem with most mantras (and this one is no exception) is that they are only true in an ideal world.

Investing with a pre‐purchase survey

Those who invest in new start-up technology companies are taking a chance. There’s a very good reason why venture capital is called ‘dare capital’ in Dutch. However, the sign of a good fund manager is making sure that you’re aware of the risks as far as possible and then carefully weighing up the investment decision. ‘Doing your homework’ as many an investor would put it. This is something SIG offers support in more and more. This happened at the end of 2011 with investment company Chrysalix SET.
