Many of these wastes can be directly addressed with adjustments to a Scrum Team’s Definition of Done (DoD), which is a clear, shared understanding of what must be achieved to consider a work product complete. Three different types of wastes that can be seen in these environments include partially completed work, unutilized talent, and excessive handoffs.

Table of Contents

1. Partially Completed Work:

Partially completed work refers to any work that has been started but not finished at the end of a development cycle. This partly done work often goes into the inventory and becomes a form of ‘waste’ that not only requires additional resources to manage but can also lead to more significant issues such as technical debt.

How to Address:

The nature of Scrum involves working in short iterations or ‘Sprints’. By incorporating the complete closure of tasks into the DoD, a Scrum team can mitigate this waste. For instance, the DoD might state that a ‘User Story is considered Done when it is coded to standards, reviewed, tested, accepted by Product Owners, and ready to be shipped to customers’. This ensures that every item is done in full by the end of the sprint, thus minimizing partially completed work.

2. Unutilized Talent:

When valuable skills or abilities of a team member are not effectively employed, this is considered as unutilized talent. This kind of waste is detrimental as it demoralizes the affected team members and prevents the team from achieving peak performance.

How to Address:

A diverse DoD emphasizing collaboration and cross-functional behavior can help in avoiding this waste. Allowing team members to contribute to various aspects of development ensures that they are fully utilized. For example, the team’s DoD could specify that ‘All development team members will participate in code reviews’, promoting active engagement and the sharing of knowledge.

3. Excessive Handoffs:

A product passing through multiple hands, stages, teams, or shifts during its development can often cause a waste of resources, longer lead times, and potential miscommunications. This is known as ‘excessive handoffs’.

How to Address:

The DoD can be crafted to promote collective ownership and discourage silos. This could involve conditions like ‘Any member of the team can pick up a backlog item and get it to Done’. Encouraging the team to work together reduces the number of handoffs and the risk of communication errors.

Waste What it is How the DoD can Address it
Partially Completed Work Work that is started but not finished at the end of a development cycle Incorporating complete closure of tasks to ensure all work is finished by the end of each sprint
Unutilized Talent Valuable skills or abilities of team members not being used effectively Emphasizing collaboration and cross-functionality to fully utilize all team members
Excessive Handoffs Product passes through multiple hands/stages during development causing resource waste and potential miscommunication Promoting team-wide task ownership to reduce handoffs and risk of communication errors

To sum up, an effective and comprehensive DoD addresses many types of waste seen in product development environments, thus achieving more lean and efficient workflows. You might want to take these factors into account when forming or refining your team’s DoD during A-CSD exam preparations or in real-world Scrum settings.

Practice Test

True or False: The three types of wastes in product development environments are defects, overproduction, and transportation.

  • True
  • False

Answer: False

Explanation: Although these could be wastes in product development, they are not the only or major sources. Example of waste includes, partially done work, extra processes, and extra features, among others.

Which of the following can be considered a waste in product development environments?

  • A) Perfectly functioning application
  • B) Delivering additional features that users didn’t request
  • C) Developing application based on client’s instructions
  • D) Efficient communication between the client and team

Answer: B

Explanation: Unnecessary features are considered waste because they consume development time, testing time, and can add complexity without adding value.

Which of these is a recommended way to address wastage in a Scrum Team’s Definition of Done?

  • A) Increase product features
  • B) Minimize work-in-progress
  • C) Increase team size
  • D) Decrease testing

Answer: B

Explanation: Minimizing work-in-progress (partially done work) is a lean principle that helps teams focus and deliver value faster, reducing waste in the process.

True or False: Task switching is a type of waste in product development.

  • True
  • False

Answer: True

Explanation: Task switching, also known as context switching, is considered waste as it reduces productivity and increases the time it takes to complete tasks.

Overproduction is addressed in a Scrum Team’s Definition of Done by:

  • A) Increasing production
  • B) Strict adherence to client’s requirements
  • C) Delivering more than what is required
  • D) Increasing team size

Answer: B

Explanation: Overproduction is mitigated by sticking to the requirements and the work agreed upon in the sprint, not producing more than necessary.

Which is NOT a way to minimize extra processes in a Scrum Team’s Definition of Done?

  • A) Streamlining processes
  • B) Minimizing documentation
  • C) Adding more processes
  • D) Using automation where applicable

Answer: C

Explanation: Adding more processes doesn’t minimize extra processes, instead it could lead to even more waste.

Waiting for approvals or sign-offs is a type of waste known as:

  • A) Task switching
  • B) Overproduction
  • C) Waiting
  • D) Extra features

Answer: C

Explanation: Waiting is a type of waste that occurs anytime work in progress is sitting idle, not being worked on.

Which of the following can be used to address the waste of motion in a Scrum team’s Definition of Done?

  • A) Increased communication
  • B) Task delegation
  • C) Less transportation
  • D) Declaring daily goals

Answer: A

Explanation: Increased communication can reduce the waste of motion, so that work doesn’t have to be re-done or duplicated unnecessarily.

Which of the following can be used to minimize the waste of defects?

  • A) Increase production
  • B) Increase team size
  • C) Testing thoroughly
  • D) Decrease communication

Answer: C

Explanation: Thorough testing is a way to minimize defects and therefore, reduce waste.

Unnecessary features is also known as:

  • A) Overproduction
  • B) Extra Features
  • C) Overprocessing
  • D) Motion

Answer: B

Explanation: Extra features refer to incorporating more features than requested or needed, which leads to a waste of resources.

Interview Questions

What are the three different types of wastes in product development environments?

The three different types of wastes in product development environments include Muda (non-value-added work), Mura (inconsistency), and Muri (overburden).

How can a Scrum Team address Muda, or non-value-added work, in their Definition of Done?

A Scrum Team can address Muda by clearly defining what counts as “Done” for each product increment. This includes setting quality standards and ensuring that all work done contributes directly towards the final product, thereby eliminating wasted efforts on non-value-added work.

How can a Scrum Team tackle Mura, or inconsistency, in their Definition of Done?

To tackle Mura, the Scrum Team should maintain consistent processes and standards across all sprints. This involves having a clear and consistent Definition of Done that all team members understand and follow.

How can Muri, or overburden, be minimized in a Scrum Team’s Definition of Done?

To minimize Muri, the Scrum Team needs to ensure that the workload is evenly distributed among team members and that they are not overloaded with tasks. The Definition of Done should reflect a realistic and sustainable pace of work.

What is the significance of the Definition of Done in managing wastes in a Scrum environment?

The Definition of Done ensures that every task completed adds value to the product. This avoids wastes like rework, delays, or unnecessary tasks, and promotes efficiency in the development process.

What role does the Scrum Master play in managing wastes in product development?

The Scrum Master facilitates the Scrum Team in identifying and eliminating waste by continually refining the Definition of Done, and encouraging adherence to Scrum principles and values.

Which of the wastes in product development is directly linked to task inefficiencies and how can it be resolved?

Muda, or non-value-added work, is directly linked to task inefficiencies. It can be resolved by ensuring all tasks in the Definition of Done directly contribute to the desired final product.

How can a lack of clarity or ambiguity in tasks contribute to waste in product development environments?

Lack of clarity or ambiguity in tasks can lead to misunderstandings, rework, and delays, which are forms of Muda. This can be avoided by having a clear and shared understanding of the Definition of Done.

How does continual reassessment and adjustment of the Definition of Done help manage waste?

By continually reassessing and adjusting the Definition of Done, the Scrum Team can ensure it remains relevant and value-adding, thereby preventing wasted work on irrelevant or unnecessary tasks.

In what ways can the Scrum Team identify waste in their product development processes?

The Scrum Team can identify waste through regular retrospectives, where they critically evaluate their processes and look for any non-value-added work, inconsistencies, or overburden.
