18 years have passed since the publication of the agile development manifesto, which is a really long time in IT. However, we still do not use it as often as we would like. Agile methodologies are not universally applicable to all. For which projects and customers is therefore agile suitable and how can it really look like in the real life of agency development?
In case you have never heard about agile development, start with principles behind the agile manifesto. These are the principles upon which the individual methodologies were built. Among the most known are Scrum or Kanban.
How does it work?
At the beginning, the project is split into shorter time periods called sprint or iteration. The work is only planned for a couple of weeks ahead (typically two or three).
Before the beginning of each sprint, the development team meets with the customer (sprint planning) and together, they negotiate what will be its content. This content should not be changed during the sprint. All possible changes and new functionalities that cannot be incorporated into the sprint are put into the backlog, which is a list of future tasks.
Within each sprint, a short technical analysis takes place as well as UX/UI design, development and testing. The output is a functional version of the application that can be presented. That is what makes agile different from the classical waterfall model where all work is connected in a linear manner (just like a waterfall). At the beginning, the technical analysis of the whole application takes place, after that UX/UI design of the whole application and so on.
It is necessary to realise that a sprint is not a commitment, but a recommendation. It can happen that the amount of work is too big and it is impossible to make it in the given time. It can also happen that the amount of planned work is too small and some tasks from the backlog can be added. These planning mistakes are to be learnt from for the next sprint.
The base of agile development is close cooperation with the customer and regular communication. The customer is included in the whole development process and receives a product that they cooperate on throughout. In Ackee, we are trying to do most new projects in an agile way. Thanks to that, we are able to deliver great apps in a very short time and save time and money.
All hail to Agile
When we look at all the advantages of agile, is there even a reason to use another methodology? Yes!
The first principle of agile development is “...accommodate the client with timely and continuous delivery of valuable software.” However, that is not always a satisfactory way. In order for agile to work, the customer must be interested and most of all have time to cooperate with the development team. Product owner (the person responsible for product decisions) must be able to communicate daily with the team and cooperate on the development through the decisions on a daily basis, take part in sprint planning and have some overview of the development.
Based on another principle of agile development, changes in requirements are welcome. That is obviously a good thing - the world is evolving quickly and the product has to as well. But here, the product owner plays a key role and has to be able to decide which functionality is important and what is just a small enhancement. Wrong prioritization can cause that there is sprint after sprint and in the end there is no product or money. It is therefore clear that in agile development, the role of the product owner representing the interests of the customer is absolutely key to success.
When to choose agile and when not to?
Agile methodologies are great for the fast development of software that changes over time. Agile is however not universally applicable to all projects and to all customers. The success is very dependent on the product owner role, whose absence or indecisiveness can paralyze the whole development team.
When to choose agile and when not to? The classical answer goes: in case the customer does not know exactly what they want, go with agile. If you are a customer, choose an agency that has experience and can advise you on the best development method for your project. The most important, however, is the approach: agile projects require time, commitment and endurance. In case you don't have those at your disposal, create the project together: analyse requirements, design a solution and test it. As soon as you have this assignment ready, you can go on with waterfall. It is no mistake even in 2019.
