A

Working with DMAIC is an iterative exercise.

For the purpose of process improvement, we recommend DMAIC as a five-phase improvement cycle:

  • Define: clarify the problem and break it down if needed, define requirements, set target and objective
  • Measure: validate the process, refine the problem, measure inputs, key steps and outcomes
  • Analyze: develop cause and effect relationships, identify the vital few root causes, validate hypotheses
  • Improve: develop ideas to remove root causes, test solutions, standardize solutions and measure results
  • Control: establish standard operating procedures to communicate the way of working and maintain performance, correct problems as needed, present result to the sponsor, and start the next iteration

Once the problem is clarified, it is often broken down in its contributing parts. It’s important to keep focusing on customer-centric values. Put the customer first in your problem solving activity. If you have a hard time defining
a problem, looking at a process area from
a:

  • Muri, Mura or Muda perspective.

Where is the overburden, where is the variation, and where is the waste? In this regard, it is important to note that waste is always a symptom of a problem and not the problem itself.

Q

The results of the Define phase consists of four deliverables:

A

The results of the Define phase consists of four deliverables:

  1. A completed Kaizen charter covering the problem statement, business impact, goal statement(s), scope, defined team which is presented to the sponsor and stakeholders. The team should try to capture their
    communication towards stakeholders
    on one A3 and use an updated version
    to visualize their problem solving effort.
  2. Documentation showing what customers are affected by this Kaizen and what their needs are;
  3. A map of the process that captures the boundaries and scope of the process to be improved (SIPOC). This map helps the team to verify what the inputs of the process are and if they match the outputs of the supplying upstream process, and what
    the process outputs are and if they match the expectations of the customers of the downstream process;
  4. Rules of engagement of the team and an understanding of their way of working throughout the rest of the event

Q

In the Measure Phase, the Kaizen team provides factual evidence that a problem or an opportunity actually exists. The starting point is the question: “What is our performance?” Most of the Kaizen team’s metrics tend to be process-centric and time- oriented. Process times should be captured for each step of the process. This is the actual elapsed time for each step in the process and it includes:

Process times should be captured for each step of the process. This is the actual elapsed time for each step in the process and it includes:

• Lead Time: is the total elapsed time between the customer placing an order and the delivery of the product or service.

*Cycle Time: is the time per unit of work in the value stream or total cycle time is the time from start of the value stream to its conclusion. Cycle time is impacted by wait or setup timeas well as the capacity and throughput at the limiting work station, constraint or bottleneck in the process. A key element to remember is that the process cannot produce faster than the limiting work station or constraint.

  • Machine Time: for the automated portion of the process
  • Queue Time: time while materials of information wait in queues

The purpose of the Measure phase is to thoroughly understand the current state of the process and collect reliable data on process speed, quality, and costs that you will use to expose the underlying causes of problems. Therefore, the deliverables of this phase are:

  • A Value Stream Map that displays baseline measures on time, quality, and cost. The map should show the main process steps relevant to the project scope, customer demand rate, and cycle times for those steps. Supplier and customer loops need to be clearly identified and input and output clearly understood by the team
  • An updated Kaizen charter or A3 which is presented to the Kaizen sponsor

Q

Analyse phase The primary deliverables typically include:

A

Analyse phase The primary deliverables typically include:

  • a list of improvement opportunities,
  • data analysis that describes a ‘before’ and proposed ‘after’ state,
  • identification of the problem’s root causes and their priority.
    The team answers 4 questions:
    1. What are the causes?
    2. What are the effects?
    3. What is the relationship between causes and effects?
    4. How important is each cause regarding the problem?

An updated Kaizen charter or A3 should, again, be presented to the Kaizen sponsor.

A

The DMAIC methodology is a powerful five-phase approach to addressing a process that needs improvement. The keys to having a successful Kaizen

Events are:
• Establishing that the project is a business priority
• Understanding the true requirements for the process
• Using data to tell the story
• Picking the right tool for the right situation
• Communicating the Kaizen goals, accomplishments and successes
• Building credibility and support for the Kaizen

23
Q

The Kaizen Charter / A3 Visualization is:

A

The Kaizen Charter / A3 Visualization is:

Next to a general identification of the Kaizen, the team, and the process area, its content is: the problem, the background, the current condition, the target condition, the countermeasures, the plan to implement them and possible follow-up actions. This tool is used throughout the Kaizen event to record the results.

24
Q

The Pareto Diagram is:

A

The Pareto Diagram is:

A type of chart that contains both bars and a line graph, where the cumulative total is represented by the line. The purpose of the Pareto chart is to highlight the most important root causes of the problem among a (typically large) set of factors. This tool is mainly used in the Analyze phase.

25
Q

The Value Stream Map is:

A

The Value Stream Map is:

A method for analyzing the current state and future state for the series of events that take a product or service from its beginning through to the customer. Key metrics associated with value stream mapping are value adding times and no value adding times. The VSM is developed in the Analyze phase.

26
Q

The 5 Why Technique is:

A

The 5 Why Technique is:

An iterative question-asking technique used to explore the cause-and- effect relationships underlying a particular problem, used in the Analyze phase. The primary goal of the technique is to determine the root cause of a defect or problem

27
Q

The Fishbone or Ishikawa Diagram is:

A

The Fishbone or Ishikawa Diagram is:

A type of relationship diagram that shows the causes of a specific event usually grouped into major categories to identify sources of variation. Categories most commonly used in Lean IT are People, Process, Policy and Technology. This tool is mainly used in the Analyze phase.

28
Q

The Solution Matrix is:

A

The Solution Matrix is:

A matrix, used in the Improve phase, in which solutions are plotted after an impact and feasibility analysis, to visually demonstrate which solution should be pursued with the highest priority.
