Empiricism is a philosophical perspective that emphasizes the importance of experience and observation in the acquisition of knowledge. In the context of Scrum, it informs the principles and practices, giving rise to an iterative and incremental software development approach.
In Scrum, empiricism is mainly applied in three key principles: Transparency, Inspection, and Adaptation. Each of the principles works collaboratively to allow teams to manage and control their work, thus enhancing its effectiveness.
1. Transparency:
In Scrum, transparency is related to the visible aspects of the product development efforts. This includes the progress on the current Sprint, the Product Backlog, and the known issues. It’s about being open and clear about all the work, decisions, and actions. All team members should have a shared understanding of ‘what’ needs to be done and ‘how’ it’s been done.
Example: The Product Owner presents the Product Backlog items during the Sprint planning meeting to ensure every team member understands aim of the task.
2. Inspection:
Scrum emphasises regular inspection of both the product being developed and the methods and practices used in development. The aim is to detect undesirable variances or issues early and make necessary amendments.
Example: Daily stand-up meetings or ‘scrums’ are a key inspection practice. During these meetings, team members assess their progress towards the Sprint Goal and plan activities for the next 24 hours.
3. Adaptation:
If the team identifies issues that are hindering their progress or opportunities to improve their work, they must make necessary adjustments to maintain the effectiveness and improve the overall performance. This principle is crucial to Scrum’s core as it allows the team to learn from experience and continuously improve their process and product.
Example: Sprint Retrospective meeting is a key adaptation practice. The Scrum Team inspects itself and creates a plan for improvements to be enacted during the next Sprint.
| Empirical Principle | Scrum Implementation | Importance |
|---|---|---|
| Transparency | Clear Product Backlog, Sprint Goals | Ensures mutual understanding |
| Inspection | Regular Stand-up meetings, Sprint review | Allows early detection of issues |
| Adaptation | Sprint retrospectives, backlog refinement | Encourages continuous improvement |
However, it’s crucial to note that merely following the Scrum framework doesn’t guarantee success. It’s the effective application of empiricism – the iterative process of transparency, inspection, and adaptation – that increases the chances of creating a successful product.
In the context of Scrum, empiricism is about constantly learning and adjusting to the reality of work. It is about turning every experience into a learning opportunity and using the lessons learned to constantly improve and create better products. The ultimate goal is to deliver the highest possible value to customers, and empiricism is the underlying philosophical principle that guides teams towards this goal.

Interview Questions
What is Empiricism as per the Scrum framework?
Empiricism in the Scrum context refers to making decisions based on what is known and observed. It suggests that knowledge comes from experience and decisions are made based on what is observed.
What are the three pillars of empirical process control in Scrum?
The three pillars of empirical process control in Scrum are Transparency, Inspection, and Adaptation.
How is Transparency implemented in Scrum?
In Scrum, Transparency is implemented by making all aspects of the process visible to those responsible for the outcome. This includes the process, the workflow, project progress, goals etc.
How is Inspection implemented in Scrum?
Inspection in Scrum is taken care of through various events and artifacts like daily scrum, sprint review, sprint retrospective and inspection of the product backlog, sprint backlog, and the increment.
How does Adaptation play a critical role in Scrum?
Adaptation allows for adjustments to be made whenever the team members inspect and realise that something isn’t going as planned or aimed. It’s the act of incorporating changes to get improved results.
How does Empiricism differentiate Scrum from the traditional project management approach?
Unlike the traditional approach where a project plan is set in advance, Scrum, based on empiricism, accepts that the plan will have to be adapted as work progresses and new knowledge is gained.
Is Empiricism strictly applicable only for Scrum?
No, Empiricism is a general approach used in various iterative and incremental frameworks like Scrum, Kanban, etc., and is not limited to Scrum alone.
How does Empiricism cater to unpredictability in Scrum?
Empiricism handles unpredictability by accepting it instead of trying to control it. It provides mechanisms to inspect and adapt based on the changes and real-life situations encountered during the project development.
How did Empiricism contribute to the success of the Scrum framework?
Empiricism contributed to the success of Scrum by enabling decision making based on real-time, observable results instead of assumptions. It led to realistic progress tracking and more valid predictions.
Can you explain how the empirical nature of Scrum supports continuous improvement?
Empirical nature of Scrum supports continuous improvement by promoting regular reflection (Retrospective Meetings) on successes and failures and modifying the process or product accordingly for better results in the next iteration.
How often does Inspection occur in a Scrum environment?
In a Scrum environment, inspection happens at a frequency that does not interrupt work and provides timely valuable updates. Ideally, it occurs during the daily scrum, sprint review, and sprint retrospective.
What would be an outcome of not implementing empirical process control correctly in Scrum?
Not implementing empirical process control may lead to mismanagement of information and progress, less transparency, increased risks and issues, and a decrease in product quality due to lack of timely inspections and adaptations.
How does Empiricism govern the Scrum Artifacts?
Empiricism governs the Scrum Artifacts (Product Backlog, Sprint Backlog, and Increment) by making them transparent so that they can be inspected and any necessary adaptations can be made to minimize any unpredictability.
In what way does Empiricism influence Scrum Roles?
Empiricism influences Scrum roles by empowering them with decision-making rights backed by their experience and real-time data. For instance, the Product Owner makes prioritization decisions based on customer feedback and team capacity.
What is empirical evidence in a Scrum context?
Empirical evidence in a Scrum context refers to the tangible proof of progress or issues such as completed work items, coded features, or bugs found. These are factual pieces of information derived from direct observation or experience during the project.
