Right Software: On Schedule, Defect Free – What to Do If It’s Not Possible

You would definitely like to deliver the right software without defect on schedule. But in real life…

You would definitely like to deliver the right software without defect on schedule. But in real life…

Imagine a situation where your software delivery date is very near and everything is under control. You are almost ready with the tested software. Suddenly you receive a request for change from the user.

Your first reaction would be not to entertain the change request now and postpone it for later cycle. But after discussion with the user you realize that without that change the software would loose most of its effectiveness.

Now what do you do?

If you are following traditional methodology then your decision would be simply – you would go by the signed-off requirement and deliver the software. If that is not acceptable to the user then you would ask for an extension. After all, if user can change requirement so late in the life-cycle then you can definitely ask for more time.

But, if you are following agile methodology…

“you welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.”

So, what do you do?

  • Do you compromise the quality but incorporate the change and release the software? Or,
  • Do you release the software without the change and try to convince the user that the changes would be done in the next iteration? Or,
  • Do you delay the release to properly incorporate the change?

If you have been developing software you would be constantly facing this dilemma.

Adopting Agile would not eliminate the problem but change your attitude towards the problem.

The Internet of Things will challenge the status quo of how IT and development organizations operate. Or will it? Certainly the fog layer of IoT requires special insights about data ontology, security and transactional integrity. But the developmental challenges are the same: People, Process and Platform and how we integrate our thinking to solve complicated problems. In his session at 19th Cloud Expo, Craig Sproule, CEO of Metavine, will demonstrate how to move beyond today's coding paradigm ...
DevOps at Cloud Expo, taking place Nov 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA, is co-located with 19th Cloud Expo and will feature technical sessions from a rock star conference faculty and the leading industry players in the world. The widespread success of cloud computing is driving the DevOps revolution in enterprise IT. Now as never before, development teams must communicate and collaborate in a dynamic, 24/7/365 environment. There is no time to wait for long dev...
Cognitive Computing is becoming the foundation for a new generation of solutions that have the potential to transform business. Unlike traditional approaches to building solutions, a cognitive computing approach allows the data to help determine the way applications are designed. This contrasts with conventional software development that begins with defining logic based on the current way a business operates. In her session at 18th Cloud Expo, Judith S. Hurwitz, President and CEO of Hurwitz & ...
Fact is, enterprises have significant legacy voice infrastructure that’s costly to replace with pure IP solutions. How can we bring this analog infrastructure into our shiny new cloud applications? There are proven methods to bind both legacy voice applications and traditional PSTN audio into cloud-based applications and services at a carrier scale. Some of the most successful implementations leverage WebRTC, WebSockets, SIP and other open source technologies. In his session at @ThingsExpo, Da...

Digital transformation is too big and important for our future success to not understand the rules that apply to it. The first three rules for winning in this age of hyper-digital transformation are: Advantages in speed, analytics and operational tempos must be captured by implementing an optimized information logistics system (OILS) Real-time operational tempos (IT, people and business processes) must be achieved Businesses that can "analyze data and act and with speed" will dominate those t...
