The recent Invisible Thread blog on ‘ The Mars Climate Orbiter: what, why, and lessons learned ’ made me wonder if we have lost the art of good requirements engineering? Both teams went off to work on their boxes, without worrying too much what was in the other box.
New approaches to development, such as the use of User Stories in Extreme Programming and Agile, or more model based approaches such as Model Driven Software Engineering and the use of SysML... [More]
Built in the mid to late 90’s, the Mars Climate Orbiter was fitted with the most advanced technology of its time, and it featured dual redundant systems and triple redundant software copies! What could possibly go wrong?
It launched in December 1998 - everything was going according to plan. By September 1999, it approached Mars and attempted to go into orbit. Then - poof - it went out of radio contact! Two days later, it was officially declared "lost". The probe ventured too close to Mars, plummeted into its... [More]
If the tool you’re using does not do what you need it to do in the way you were expecting, is the tool bad? Should it be consigned to a shelf to gather dust?
Having worked with software tools for a number of years, I understand that they all have their own personalities and quirks. It is always important for users to be formally trained in the use of the tools they use within their organization; however, in today's business climate not everyone has that luxury.
In this new blog series, I will look... [More]
Have you heard about IBM Rational DOORS Next Generation ? It is the new version of IBM Rational DOORS, which is the requirements management module in the IBM Systems and Software Engineering solution.
If you are already using IBM Rational DOORS , don't get upset over the transition to Rational DOORS Next Generation! This is a transition that does not have to happen all at once and will probably affect clients in many different ways. If you are just beginning to explore Rational DOORS,... [More]
When planning for DevOps I always first think about “What is the best I can achieve?” Comparing the ideal with the reality then helps me to define the roadmap of changes I have to apply.
Robb Wiedrich talked in his recent blog post about DevOps best practices in the area of principles to adopt. I want to focus more on the workflow view here. Sorting out what to do in which step helps us to define the overall process and the roles involved.
So let's have a look at a very... [More]
In today’s challenging economy, businesses are under increased pressure to reduce overall costs while mitigating and controlling risks. The reality is that many businesses struggle to successfully deliver quality software on time and on budget that meets their market needs. Why is it so difficult to deliver a product that aligns to the business goals?
Organizations face a combination of technology challenges due to their complex IT environments. These environments serve multiple business functions, consist of large... [More]
What's next for the first, crucial step in successful product development
We’ve written many times here about the changing nature of the products and systems that we use in our personal and business lives. The increase in software is the invisible thread that is guiding product innovation and connecting a planet of "intelligent" things. We’ve also talked about the increasing complexity of such products and the challenges that multidisciplinary engineering teams... [More]
Cast your mind back to (or if you’re young enough, just imagine!) the days before the world wide web. You’re doing some research for studies or your hobby, sitting in a library surrounded by books. You have so many different places to look for information, in lots of different formats, and perhaps your local library doesn’t even have all the sources you need. You have to jump in the car and travel to collate all the necessary input.
Fast forward to the present day, and a web browser is your gateway to a wealth of information. Search... [More]

Creating high quality products has its own significant share of contribution from testing. In a rapidly changing world, organizations have to develop complex products with short development time frames. Coupled with it, if the products are released for end consumers which can range in millions; an organization has to be very careful about the quality of the releases. The paradigm of testing is changing with these challenges and the roles and responsibilities of developers or testers are still evolving. An effective practice is to do the testing... [More]

Similar to many targeted
industries that benefit from Rational's industry solutions, the Energy and Utilities
(E&U) vertical is increasingly adopting both CLM and the IBM industry
framework SAFE. Although E&U companies are slowly adopting the best
practices in delivering cutting edge transmission and distribution systems, the
energy generation side of the E&U’s (especially the nuclear industry) is
noticeably behind other verticals in its transformation to software intensive
systems. However, as worldwide investment in nuclear... [More]
