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]
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]
We chose the name "Innovate" for our annual conference because it's focused on the development and delivery of software. And software innovation is where the competitive opportunities lie these days. But creating software is no easy task. Whether it's targeted for IT applications or embedded products, software creation remains a complicated challenge. What should IT and product & systems teams be thinking about these days, as they try to improve their capabilities in software development and delivery? Here are my five top... [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]
In my job, I routinely find myself talking with clients about using modeling to support their systems engineering activities. The discussion usually focuses on the challenges a team is having, and most of their difficulty can often be traced back to a lack of understanding of what modeling is. This is the same issue I saw many students struggling with when I taught introductory modeling classes. In this blog post, I will try to present modeling as simply a formalization of what we, as humans, do all the time: abstract. We do this without even... [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]
Standards and tools use signals potential acceleration of productivity and an innovation curve
A century ago, assembly line production caused a paradigm shift in the automobile industry. The transition from handcrafting each car to manufacturing based on a standardized template, using tools, led to an exponential increase in productivity and efficiency. With the production of software now constituting a significant proportion of the value of a modern car, the stage is set for a similar boost in efficiency with widespread adoption of tools... [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]
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]
Test drive the new COBOL compiler for free for 90 days
Enterprise COBOL for z/OS V5.1 was rearchitected to include an advanced technology framework for optimizing COBOL applications. It provides significant performance improvements and helps reduce processor utilization and operating costs for running business critical applications on System z. Read more about it in the IBM Systems Magazine article Enterprise COBOL 5.1 – Where Tradition Meets Innovation .
Performance benefit can sometimes be difficult to quantify because it... [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]
The "Systems" perspective: How do we get to real innovation?
Complexity seems to be the arch enemy of product innovation. We frequently hear from our customers statements such as:
Every time I fix something in one place, I break two other things. - Software engineer
It’ll take me ages to determine the impact of swapping this part. - Mechanical engineer
I can’t tell which the version of software is designed for my PCB. - Electrical engineer
The IBM Rational team believes that product and systems... [More]
It’s a new era of technology , brought forth by intelligent systems and smarter products. We are building a smarter planet , by changing the way we use technology .
Governments are using intelligent systems to plan, prevent and prepare
Smart cities are digitally connected and optimized , using data from transportation systems, energy management systems, and water supply systems to plan for unexpected events, prevent strained resources and prepare for growth and congestion in the future.
For all these systems to work... [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]
