There are a variety of concepts that help identify improvements to a work system, particularly in the context of Scrum development. These concepts provide insight and guidelines to streamline processes, improve productivity and increase overall work efficiency. In this article, we will discuss three key concepts: Process Analysis, Value Stream Mapping, and the Deming Cycle:
1. Process Analysis:
Process Analysis refers to the systematic review of a work process to determine how work is being performed and how it can be optimized. It is commonly used to identify inefficiencies, redundancies or bottlenecks in the workflow. It involves identifying the tasks necessary for product completion, examining how these tasks are being performed currently, and making recommendations for improvement.
For example, in Scrum Development, a team may analyze their Sprint process to understand why certain goals aren’t being reached. They might find out that communication between team members is causing delays in task completion. In this case, possible improvements could be setting up regular meetings to update each other more frequently or using project management tools for better tracking and transparency.
2. Value Stream Mapping:
This drill-down technique is used to understand and optimize a process by mapping out every single step of a workflow, and identifying the value and waste in each step. The “value” refers to what the customer would be willing to pay for, while “waste” refers to any step that doesn’t contribute to the final value.
In a Scrum team, for instance, the Product Owner, Scrum Master, and the Development Team could use Value Stream Mapping to visualize how epics, features, and user stories move from the product backlog to the final product. This will help in identifying the areas causing delays, wasteful activities or tasks leading to work redundant.
For example, a step in the workflow might involve a developer waiting for the approval from a manager before they can move forward, this can be identified as a waste because it slows down the process and does not necessarily contribute to the value of the final product.
3. The Deming Cycle (Plan-Do-Check-Act):
The Deming Cycle, also known as PDSA (Plan-Do-Study-Act), is a continuous quality improvement model consisting of a logical sequence of four repetitive steps for continuous improvement and learning: Plan, Do, Check, and Act.
In the Scrum framework, teams can apply the Deming Cycle in every sprint. Let’s see how:
- Plan: Setting Sprint goals, planning the tasks and resources needed to achieve these goals.
- Do: Implementing and working on the plan.
- Check: Reviewing the work at the end of the Sprint during the Sprint Review and Retrospective meetings.
- Act: Implementing improvements in the next Sprint based on the learnings.
To summarize, Process Analysis, Value Stream Mapping, and the Deming PDCA cycle are valuable tools to systematically identify improvements in any work system, making them particularly useful in a Scrum environment. By continuously evaluating and improving the workflow, teams can deliver higher value to the customers while eliminating waste and inefficiencies.
