Scrum’s Three Pillars
Scrum Definition
Scrum is a framework that guides people in a project to achieve project goals by using principles of Empiricism, empiricism is a process where we frequently inspect the work done by the team and keep course correction while moving on.
Scrum Theory
Scrum is based on empiricism and reducing waste after observing the process keenly that is called lean thinking.
The three pillars of Scrum that uphold every implementation of empirical process control are Transparency, Inspection, and Adaptation as shown in the Figure below:
Transparency
Transparency in projects is very important, in order to make the right decisions to create value for the Work the team is doing for the customers and to the people delivering the work and reduce risk.
There are ceremonies and artifacts which adds to transparency are daily scrum calls, sprint review, Burndown charts, product backlogs, sprint retrospective, definitions of done, etc
Inspection
Scrum artifacts are frequently inspected and progress towards a sprint goal to detect if we are on track with respect to timeline, functionality, the process also so as to check if what we are building is relevant to the current market environment. Inspection in Scrum can be realized by scrum activities such as:
Daily Stand-ups, Sprint Review and Sprint Retrospective provides us opportunities
Scrum team uses ceremonies for inspection like daily stand-up for checking progress towards sprint goal and adapting actionable -plan to meet the sprint goal
Getting feedback from customers and stakeholders during sprint review and also sprint Retrospective for improving team’s process or any other thing other than requirements which can be improved in order to deliver value.
Adaptation
In scrum, if after inspecting the product or process from various ceremonies in scrum we observe that something deviates from acceptable limits then we need to course-correct as we go forward and adjustments must be made to reduce further deviations.
Adaptions become easy with self-managing and empowered teams
Summary
Scrum is a lightweight framework that follows empirical and lean thinking approaches to get success in the project.
The empirical approach follows to inspect and adapt frequently to make adjustments if need be, based on the ceremonies, roles, artifacts, commitments which scrum has, following we add value to the end product which leads to lower risk and it also tells are we building the right product for our customer in the current market environment.
The roles, events, and artifacts only work because of their adherence to value-based incremental improvements produced by embracing frequent feedback and embracing change.
