A mobile application is a way to fulfill an objective. What is the problem that the application should solve? What is the gap between the current situation and the desired situation? The answer to these questions makes it possible to define the project's “north star”. This north star is Product Vision. It is essential to prioritize functionalities and to involve the team in order to ensure that at all times we are creating a simple product, whose value can be understood by users in a matter of minutes. But who will find the answers to these essential questions? Who will be the guarantor of the Product vision? It's the Product Manager. Today, its role is all the more important as user needs and market trends change rapidly, the need for adaptation is growing, and the attention of mobile users is shared with many other things.

The first step is to define the goal you want to achieve with your application. In other words, to define a strategy for your product, by:

• asking you about what the product brings to us and to our business

• identifying the progress that we want users to make with the product

• understanding the needs of users and the challenges they face today

• determining its position in its market

• framing the profile of its target users

All of these elements make up the Product Discovery phase. At the end of this stage, you will have imagined and prioritized functionalities to get started!

At BAM, our Tech Leads are based on the quality theory of two major books:

• “Accelerate, the science of devops” (Nicole Forsgren, Jez Humble, Gene Kim)
• “The Toyota Way of Dantotsu Radical Quality Improvement” (Sadao Nomura)

Three key steps are implemented:

1. Measurement, quality and goal definition : We have developed an indicator based on Accelerate and Dantotsu to detect non-quality even before the first defects arrive.
2. Visualization of problems by the team : This indicator is presented at a ceremony. Defects are discussed and analyzed as a team to understand their root cause.
3. The integration of time dedicated to quality : Every day, 20% of the time is dedicated to continuous improvement, with the No. 1 objective of stopping the creation of new defects.
