It is not a secret that the mobile app development process has its peculiarities. These include:
- Strict time limitations;
- High probability that product requirements will change at particular development stages;
- A large customer base all over the globe with different needs, etc.
To handle these challenges, minimize risks, and reasonably arrange the entire workflow, software companies often opt for the Agile approach. Why? It is perfectly adjustable to the changing development environment.
Today, we will explore the most commonly used Agile variations – Scrum.
In Scrum, developers create a product in a series of iterations or sprints. Iterations have a fixed duration – normally, from two to four weeks per iteration.
It all starts with a backlog – a general list of occupations in the project. After the backlog is ready, the team splits it by iterations. At this moment, no one knows what challenges may occur later hence such division is approximate.
As a result, each sprint represents a set of tasks. One must complete those to develop the given part of the product’s functionality.
Every day a dev team holds a Scrum meeting to discuss the current progress and challenges encountered.
Whenever a new feature, module, or update comes out, the team performs its testing. Testing gives the possibility to detect bugs in time and make the product more stable.
Following the end of the iteration, the dev team demonstrates the ready version (‘demo’) of the product to a client. During this retrospective meeting, both the client and dev team discuss the obtained results and start planning the scope of work for the next sprint.
If required, the dev team revises the product or its part. This decision largely depends on customer feedback. In addition, such meetings allow the team to optimize its working process.
Scrum involves a distinct division by roles and responsibilities.
- Product owner – a person who directly communicates with a client throughout the entire development process. A product owner has a clear vision of a quality product. He/she establishes priorities depending on the importance of each particular task.
- Scum master – head of a dev team. A scrum master oversees all development processes and composes the backlog.
- Scrum team – in essence, the developers responsible for the creation of mobile apps.
Scrum Main Tools
In general, we can single out the following key elements:
- Product backlog – a complete list of product features;
- User stories – user requirements for the product;
- Iteration planning – a meeting during which all involved parties discuss what should be done within the upcoming sprint;
- Sprint backlog – the approved scope of work for the following iteration;
- Task board –a physical or virtual (such as Trello) board for project-related tasks;
- Burn-down chart – a chart that shows completed versus non-completed tasks (used for quick work progress evaluations);
- Quick briefings – daily meetings where all participants discuss the work done;
- Sprint review – the demonstration of the ready product or some part of its functionality to the client.
Adjusting Scrum to a Project
Often, you need to fit the Scrum model to the specifics of a particular project, dev team, and client. The adaptation process may go by one of these scenarios (or both):
- Timescale adjustment – reduce the sprint duration to one week. This way, your client will get new releases more often. Your team, in turn, will get feedback from him/her more often, respectively. Alternatively, you may release the new functionality once in a month depending on the project requirements.
- Scrum tool adjustment – for example, if your team members are located in different regions or even countries, you may perform daily meetings virtually. Use specialized software, like Slack or Stride, for this purpose.
Developers like Scrum for its simplicity and flexibility. It lets them quickly organize a dev team, timely respond to changes in requirements, and work closely together with a client.
