Three pillars in SCRUM:

SCRUM uses an empirical approach in order to adapt to the changing requirements of the customer. Hence this allows in situation when the inputs and outputs are more complex, and when they are not perfectly defined or repeatable.

Empirical process is considered to be more appropriate for such complex situations.

The three pillars of Scrum are transparency, inspection and adaptation as per the empirical process control.

Transparency

Transparency in Scrum can be viewed in the form of Product Backlog, Task Boards and Burndown charts, Daily Stand-ups, Retrospectives, Sprint Reviews. These are used to transfer the flow of work through cross functional team. This is one of the key advantage in SCRUM – allowing visibility with regards to the progress of work and team. This means when the team is achieving its goal, those responsible for it can be recognized and appreciated for the efforts. This works the other way as well, when the team is struggling to achieve its target , stakeholders can help and eliminate obstacles.

Transparency also ensures that the organisation and team is free from political games. In short:

  • Transparency allows in depth use of systemic thinking tools
  • Transparency enables team learning
  • Transparency allows positive management involvement and self-curtails adverse management interference

Inspection:

SCRUM is also helpful in evaluating the current state of the work and provides opportunities to see how the team is using SCRUM. This method provides understanding on the challenges faced by the team, the progress made and also the creativity used by the team to solve problems.

Hence “Inspection” of team’s work ensures that team is not most likely do a “post-mortem” when the project is complete – which rarely changes the way a project is carried out.

Adaptation

If in the process of inspection it is found that there are one or more process that deviate outside the acceptable limits and results in the product being unacceptable then the process must be adjusted. Adaption allows to make changes as per requirement to the new ideas, information and current environment of the work.

Adaptation in Scrum is depicted through:

  • Daily Standup Meetings
  • Constant Risk Identification
  • Change Requests
  • Scrum Guidance Body
  • Retrospect Sprint Meeting
  • Retrospect Project Meeting

In conclusion, transparency is an indispensable pillar of Scrum, and this pillar works hand in hand with two pillars of Scrum which is inspection and adaptation.
