When we talk about testing in the information technology industry, feature testing and regression testing immediately come to mind as the go-to procedures for ensuring software quality. These, along with non-functional testing paradigms like performance and resilience testing, are widely considered to be comprehensive. But does this conventional testing suite sufficiently address the complexities of contemporary IT projects? Perhaps there's more to consider.
Navigating the Intricacies of Modern IT Projects
Contemporary IT projects are rarely straightforward. They typically involve simultaneous updates to both front-end interfaces and back-end systems, intertwined with intricate dependencies that can be challenging to unravel. It's not uncommon for such projects to necessitate a series of smaller, strategically sequenced deployments rather than a single, sweeping update. The daunting aspect is the unpredictability: identifying all the dependencies and their potential impacts is often more of an art than a science. Many IT professionals have encountered situations where unforeseen issues force an entire deployment to be aborted and rolled back, leaving customers facing unexpected disruptions.
The Concept of Launch Mechanics
Throughout my recent work on complex projects, I've been championing a concept I refer to as "launch mechanics." This term encapsulates the entire process of introducing changes into a production environment. Depending on the situation, this can range from a straightforward procedure to a highly complex puzzle. It's critical to consider the deployment strategy early in the project lifecycle. But I advocate for going one step further: rigorously testing the launch mechanics well before the actual deployment date.
Comprehensive Testing of Launch Procedures
Testing how a change or feature will be implemented is only one side of the coin. Equally vital is the testing of rollback procedures. While many systems have established protocols for rollbacks, the complexity multiplies when multiple sequential rollbacks are required. How well do we understand the reversal process, and can we execute it flawlessly under pressure?
Reducing Technical Risk Through Thorough Preparation
By defining and pre-testing launch mechanics, we significantly mitigate the technical risk associated with IT projects and programmes. This preparatory work is not just advisable—it's imperative for modern IT deployments. Ensuring that we have a robust and resilient launch strategy in place means that when we do press the proverbial 'launch button,' we do so with confidence and a comprehensive understanding of the possible outcomes.
