How to Build the Best Action Plan for your Application

Applications are built on thousands, millions, maybe even tens of millions, lines of code. They are based on specific architecture gathering technologies, frameworks, and databases set up with their own specific architecture. If you have an action plan to improve your application on a specific issue, what will be your strategy?

Do you select one problem related to quality or take the opportunity to refactor part of your application? You know about issues coming from end users, but how do you address those inside the structure of your application?

I remember meeting with development teams and management who were trying to find the root cause of performance issues, as delays or malfunctioning of the application would severely impact the business. The old application was a mix of new and old technologies, and there was difficulty integrating the new user interface with the rest of the application.

They discussed for hours to decide which orientation they were going to take, and pressure was high. The team responsible for the user interface said that the old platform had to be rewritten, and of course the rest of the team complained that their part of the application worked well before the new interface appeared and it was the database structure that was causing performance issues. Management was totally lost, and didn’t know what to decide! And while this was going on, we could sense the business value decreasing.

We decided to analyze the entire application with CAST; using the transaction ranking method to identify issues regarding performance. The transactions are ranked using the sum of the high risks attached to each, along with the multiple methods and procedure calls.

In the CAST Dashboard, there is a view dedicated to list transactions from the end-user point of view. The transactions that appeared at the top of the list were precisely the transactions which had real performance issues. Then, it becomes easy to select the most critical defects inside one specific transaction and add them to your action plan.

These results, coming from a solution like CAST, were factual and not debatable. It highlighted the fact that defects correlated to performance issues were a combination of bad programming practices coming from different parts of the application.

We decided to work only on the transaction with the highest risk to measure improvement in terms of performance in production. In the end, all teams worked together because the root causes were links between loops bad practices, an improperly managed homemade framework datalayer, and a huge amount of data contained by tables without proper indexes.

This is just one successful way to build an effective action plan. What’s your experience? Do you have a success story about how you built an effective action plan? Be sure to share in a comment.
