Despite there are numerous methodologies for products creating in the world, these two are the most frequently mentioned leaders. Scrum and Kanban are the most used on IT projects, however, they also can be used in other areas. Not everyone understands the difference between these development methodologies but every detail in this business can increase productivity in building products. In this article, we will talk about the features of Kanban and Scrum that distinguish them from each other, and also why it makes no sense to choose only one of them.
Both Scrum and Kanban provide an opportunity to make product development flexible and capable of supporting drastic changes in requirements without significant costs. Both of them involve the division of large projects into small atomic tasks with their consistent solution called user stories. The order of solving problems is determined directly by the team taking into account objective factors (priority, complexity, the importance of the following tasks). All user stories constitute a backlog, which is a set of all the tasks necessary for the project implementation.
In general, the team plays an important role in both methodologies (which does not contradict the Agile Manifesto). The main principle is free communication between specialists and general discussions. The team usually consist of up to 9 members without a formal leader and outside control of the workflow. That’s why it’s not possible to blame only one team member in the failure: in this case, the responsibility is borne by the whole team.
Scrum Software Product Development
Usually, Scrum is referred as a more directive model due to the numerous prescriptions non-characteristic for Kanban. First of all, it envisages small multifunctional teams, in which all the specialists necessary for solving the tasks are present. Each member of the team should have a clearly defined role. Every day a meeting (so-called daily meeting) is held where the team discusses what they did yesterday and what will be done today. Scrum Master is engaged in the organization of these meetings and the work process as a whole.
The prescriptive nature of Scrum is also expressed in the fact that all the work in creating IT products is divided into sprints equal in duration. This is done to maintain a certain rhythm of work, which can be considered an inalienable part of Scrum. Typically, the length of one sprint does not exceed 1 month, but recently companies increasingly work with 2-weeks sprints. Each sprint has several consequent stages as follows:
The main indicator that is measured in Scrum is the weight of the tasks performed during the sprint, that is, the team’s performance. This helps determine when the project will be completed if the team’s performance is at a certain level.
Kanban: The Scrum’s Opposite When It Comes to Restrictions
The first thing you will feel when reading about the same stages in Kanban is freedom. The methodology is based on team communication and joint decision-making, discussions, and following common sense.
At the same time, it lacks such a valuable advantage as the ability to pinpoint when the project will be completed, which is typical of Scrum. However, it is advisable to apply Scrum not on all the projects, that’s why we need an alternative.
An important Kanban indicator is the average time for passing the task on the board. In this case, the efficiency of the team is measured by the speed of completing the task from start to finish.
Which One to Choose For Creating IT Products?
Your choice should be dictated by the features of the project itself, its requirements for the process flexibility. Despite this, the transition to flexible development methodologies is not always easy for teams. Therefore, it is recommended to start with Kanban: it is easier to implement due to fewer restrictions, you can add Scrum elements to it, if necessary. In addition, you can create cross-functional teams but still be divided into departments.
If you still can’t decide what is the best for your project, do not puzzle. These methodologies can borrow certain features of each other while remaining equally effective for software building. If you like the certainty of Scrum, and at the same time the flexibility of Kanban, you can combine separate parts of the processes from both methodologies.
Remember: the task of methodologies is to optimize processes and not complicate them. Therefore, customize them the way it is convenient for you.
