OCTOBER 2021CIOAPPLICATIONSEUROPE.COM9for clusters of cities. This allowed us to better ensure the stability of the individual services. In addition, we were able to quickly find small bugs and fix them without major customer impact.Overall, the project was a great success. The newly released delivery windows were very well received by customers and helped us improving our operations' planning. Takeaways: To be fast, not every detail needs to be defined at the beginning of an initiative or project. It can be worked out in parallel along the way. It helps to reflect regularly and make adjustments to, for example, the scope or process if necessary. A governance structure should be set up according to the project, its scope and the assigned team. It does not matter who takes the overall coordinating role. The important thing is that somebody with overarching knowledge impersonates this role - regardless of whether it is a business owner, product manager, project manager or in-house consultant. The requirements were extensively analyzed by Business Development and researched in the market. In the further course a project was set up, in which an in-house consultant supported. During the project initialization phase, it quickly became clear that a number of development teams (including the design team) would have to be involved. In addition to the pure integration of the functionality into the web shop and the warehouse management system, Operations and Customer Care applications had to be provided. Furthermore, Purchasing had to rethink its inventory limits in the procurement process to ensure sufficient stock levels in the warehouse. Integration phase: During the analysis of the dependencies, the current software products, and the current technical infrastructure, doubts arose about incorporating the new functions into production. There were too many dependencies to the payment process and to the order handling. The result was the development of a new order processing service (the Order Engine), and the connection of a new payment service provider. These efforts were not yet apparent at the start of the project and were integrated into the ongoing project. Rollout phase: As the integration progressed, there were also (as is often the case in larger projects) small delays here and there. Thus, we took another detailed look at the go-live planning and decided to take an iterative approach. First, we enabled the new payment provider. The pure backend functionality of the delivery windows went live in advance and ran in shadow mode. Then, when the store integration was ready, we went live for individual cities first and later Agility is indeed imperative today to develop requirements in line with the market
