The waterfall approach has its advantages. Besides issuing patches, this phase may also release better versions of the product. MaintenanceĪny issues that crop up in the client environment are fixed in maintenance mode.
Once all issues are fixed, the finished product is released to the customer or the market. All units are integrated and then tested again for user acceptance. The system design becomes the input here to develop small programs that are known as units. This helps in defining the hardware and system requirements and the overall architecture. The specifications from the first phase are studied here to create a suitable system design. The first phase is gathering all possible customer requirements and documenting them to plan the entire project. Generally, the output of one step becomes the input for the next.

That’s why it is essential to establish the full scope of the product before work begins. Incorporating it in further stages is not only challenging but also costly. Let’s say you missed a feature at the requirement stage. In the waterfall approach, you can’t make changes to the process.
Clearly define the requirement of customer experience upfront.They did in their paper Software Requirements: Are They Really A Problem? published in 1976.Īccording to them, to achieve a successful outcome with the waterfall, you need to: Thayer formally introduced the waterfall approach.
“I believe in this concept, but the implementation described above is risky and invites failure.”īuilding upon the foundation of Royce’s paper, Thomas E. Conceivably, that became the underpinning for the agile approach. Rather, he called it flawed, stating that an iterative approach may be better. Royce’s paper didn’t flatter the waterfall method much. Even though the article doesn’t directly mention waterfall, it does allude to it. Royce set the groundwork for the waterfall approach in his paper – Managing the Development of Large Software Systems. When you pick this method, you plan, build, and deliver your SaaS product (or a new feature) in a disciplined sequence of activities.Įvery phase and every activity within that phase is documented and approved before you start working on the succeeding one. The approach is a linear process where one task begins after the previous one is completed. It takes its name from the flow of water, i.e., one drop comes right after the other. The waterfall methodology for product management is the traditional approach. What makes them so different? And more importantly, which one should a SaaS organization use? That’s what we will unpack today. Since both methods are popular, even though they take different product development approaches, the question invariably leads to a heated debate. Make the right choice, and deadlines become a thing of the past. Make the wrong choice, and you do twice the amount of work. If you’ve been a product manager for any length of time, you’ve come across one eternal question – which of the development methodologies is better: agile or waterfall?
