Why use Scrum

The following article is a sample from the full BVOP™ Ultimate Guide and is part of the preparation for the BVOP™'s modern Agile Project Management Certification Program.

Scrum is popular, but that doesn't mean it should always be used. It has advantages.

The Waterfall method is the traditional project management approach. The Waterfall is a linear and consistent procedure. This means that in this approach, you are processing one phase after another in a linear fashion and do not have any overlap in the phases.

Example:

  • You cannot do the design before you have done the planning.
  • You can't get started before you've done the design.
  • You can't test anything before the project is ready.
  • And so on.

Scrum for rapidly changing requirements

In the real modern world, many products and organizations have to cope with rapidly changing requirements, customers, users, needs.

In Waterfall, where everything is consistent, teams need to have all the requirements at the beginning of the project, and everything is documented, every step is planned, discussed, and approved by multiple stakeholders.

Each change in the project changes the documentation, budgets, and deadlines. BVOP states that this can cause stress for many teams and participants.

When following the Waterfall methodology, it is usually challenging to offer any product to the client or organization before the end of the project.

After a certain amount of time has elapsed since the launch of the project, much of the product may no longer meet the needs of the market.

A possible problem situation would be that project stakeholder would no longer even need what they needed a long time ago.

Traditional project management is, in fact, excellent and stable, where tasks must be completed one after the other, or where detailed planning and design is required before work on the actual project begins.

The Waterfall is very suitable for businesses such as heavy industry and construction, where the direction and scope of the project remain relatively unchanged throughout the project.

Waterfall, on the other hand, may not be suitable for projects where the product needs constant adaptation to changing requirements and circumstances.

For example, if a product to be developed is a mobile application for artists or a new innovative virtual reality, Waterfall may not be the right method of operation.

One important topic in all Agile practices and Scrum is the value theme, which BVOP strongly emphasizes and generalizes to the overall Business Value idea.

For many products, value is not just a timely completion of a project, adherence to basic rules, or fit into a specific budget.

For some products, business value can be a highly usable user interface. For other products, business value will be quick work; for others, it will be readable text.

Iteration and Increment

Iterations in Scrum

Scrum is organized in cycles.

It is "iterative". It means repetitive. In Scrum, work is organized at intervals called Sprints.

Inspection and adaptation also occur iteratively within each Sprint. Scrum events (Daily Scrum, Sprint Planning, Sprint Review, and Sprint Retrospective) also take place at each iteration (repetition).

Scrum is incremental

During the iteration (Sprint, the time interval in which the team works), the team works collaboratively to create a "Potentially Shippable Product Increment".

This "increment" is a working version of the product being developed that can be made available to end-users. These increases or increments (better versions) must be fully completed. There should be no hidden, unknown work that still needs to be done.

Inspection is performed on the “incremented” product, and any adjustments made are made to create a better and more valuable product.

What is Increment?

The simplest explanation is that increment is the current version of the product you are developing. This current version contains all the previously done work on the product, plus the work done in the current sprint.

If your project is now starting and you are in the first sprint, your increment is just the ready work for the current (first) period.

If you are already in the second sprint, then your increment is simply the current version of the product ready in the previous sprint, plus the tasks you completed during the current sprint.
