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]
by Walker Royce Chief Software Economist, IBM Rational software Innovation has become synonymous with software. It’s through software that businesses can create products, systems, and services that are increasingly “instrumented, interconnected, and intelligent.” These innovations in software are becoming the source of real value to the consumer, and for many businesses it is what sets them apart from their competition. As you think about your organization, what is the biggest challenge you are facing NOW? What is NEXT if you want to... [More]
We are now accepting nominations for our 2013 class of IBM Champions for Rational software. Champions are IBM clients or partners in the technical community who motivate others toward our software solutions and services by being:
R esponsive - They are actively engaged with their peers through communities, user groups, and events.
R espected - They are experienced professionals who serve as technical mentors to their peers.
R ecognized - They extend themselves beyond their peer groups to share their expertise through social media,... [More]
There are two ends to the spectrum of thinking about how and when to reuse artifacts during product development. One end of the spectrum is to begin the process by designing for reuse. The other end of the spectrum is not developing for reuse at all and then reengineering the artifacts later to reuse. The goal of reuse is to reduce cost and improve efficiency in product development. For software designers to reduce costs, they must build an architecture with common core assets. There are two different ways that an organization can structure... [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]
It is my pleasure to announce this year's IBM Champions for Rational Software! Earlier this year, we asked you to nominate the leaders in your technical communities who represented the three "R's" of being a champion : Being responsive, respected, and recognized in the technical community. The following new and returning Rational champions stood out among the crowd. They are experienced in using Rational solutions to solve real business problems and are recognized experts in their field. They spend their own time, energy and resources... [More]
The intent of this post is to provide an insight into the world of the systems engineer that is used to working on large embedded projects. Meaning engineers that design and develop products that fly, move on tracks or wheels and float, or in some cases submerge. It is a summary of a webinar I gave in February that has since been transcribed and turned into a white paper
What is it?
Systems engineering spans all the disciplines involved in developing a product. It provides the means to specify the... [More]
Mergers and acquisitions (M&As) and corporate restructuring are normal. Deals can be worth hundreds of millions, or even billions, of dollars. Not surprisingly, we hear about M&As almost daily in the news headlines. Next time you flip open the newspaper's business section, the odds are high that at least one headline will announce some kind of M&A transaction. The upheaval caused by integrating with another organization significantly challenges the way both organizations conduct business. According to IBM research, an... [More]
A Practical Approach to Quality!
If your software and
systems development team is under 10 people, including coding, testing, and
project management, then your projects may not experience huge difficulties associated
with traceability -- i.e., the discipline that links requirements to test case
and test results. But for larger teams of 30 or more, where even a medium-size
project involves 5,000 requirements and 10,000 test
cases, the complexity can feel overwhelming.
this: If it takes 20 minutes to link the... [More]
The 20th century manufacturing revolution simplified the way people and teams worked together toward a larger goal. But when it comes to software delivery, the odds of predicting project success is still more of an art than science. Looking for a solution -- often when the problem itself isn’t clear -- IT organizations spend way too much time and energy on internal dynamics and the activities associated with production, rather than innovation and competitive goals. Most of the time, the reason for this wasted effort is poor collaboration and... [More]
Doing things on time and on budget – it does NOT matter if the
things you are doing are the wrong things. Before doing things the correct way,
it’s of vital importance for an organization to secure that the portfolio,
projects and activities are aligned with company strategy and that it’s
prioritized correctly to secure most possible value from a company’s limited
One of the biggest challenges is to make the best compromises
between contradictory projects and activities. For an organization to be
effective and... [More]
With the announcement of RELM in September, the growing importance of systems engineering has been a topic of discussion. We sat down with four of our Rational systems experts to answer some common questions about design, agile, modeling and architecture.
Meet the leaders
Dr. Keith Collyer is an expert in Requirements and Systems Engineering. He trained as an electronic engineer, later moving into software development. His interest in the “people” aspects led him into project management, quality assurance and processes, never losing... [More]
The motto of the House of Stark in the HBO series based on George R.R. Martin’s Game of Thrones is “ Winter is coming ”. With sequestration looming, significant budget cuts already enacted, and stiff global competition, Aerospace and Defense (A&D) companies are going to need to do more with less to remain competitive. Old ways, however, die hard--paper-based artifacts have been the backbone of the industry for its whole modern existence. This culture, however, comes at a very high cost, a cost it is quite clear we can no longer... [More]
by Gina Poole IBM clients know better than anyone that software and systems delivery is a rapidly changing landscape. Whether your job is in IT, or in the product & systems arena, software development is constantly impacted by new application delivery models like cloud, proliferating mobile end-point devices, shrinking delivery windows, and the blurring of organizational boundaries. So the question is, how can software and systems delivery teams ride the new technology waves of mobile, cloud, social business, etc., and turn these thorny... [More]
Why software isn’t so soft
For something with the word “soft” in the name, software is very hard indeed. Every study I’ve seen has shown that we, as an industry, are terrible at estimating how long it will take to create and not good at all at producing it without defects. There are all kinds of reasons for this, but mostly it boils down to the fact that creating software is far more akin to a craft than an engineering discipline. Each software product is lovingly sculpted from the depths of our creative minds. Developing software is... [More]
