Question
Help please. This is from Quality and Tools.
IV. Problem solving and improvement. Describe a SS problem solving situation.* Describe specifically what would happen at each step of your example (not just generically, what happens at each of the DMAIC steps). Summarize Lean; what's the point of Lean? Prepare an activity network diagram.* The task length doesn't have to be days. Outline a project using PERT, CPM, or Gantt chart* a. b. c. d. Page 4 of 5 Define the following terms per Taguchi and describe how they relate to one another: parameter, signal, noise, and robust. Pick a process and list the parameters of the process; which parameters are signals and which are noise? e.Explanation / Answer
Q1:
It is a method which is very efficient in solving several kinds of problems in business. It can be considered as one of the initial methods delegated later into SIX SIGMA, one of the most successful (project) quality management tool across different industries - It predominantly depends on statistical analysis.
DMAIC:
Define, Measure, Analyze, Improve and Control
It should be used for solving a business problem. Here is an example.
Example: The production capacity of a plant is reduced to 110Mn units/Yr and the target/actual capacity is 155Mn Units/Yr.
Define:
Measure:
Analyse:
Perform analysis using the data collected and tools output.
Improve:
Control:
Q-2:
Lean: It is a method to improve, Quality index of product produced, be it any product including a software, application, Engine, Fabric etc.,
Methods of lean: There are 8 kinds of waste which are to identify in an MU and take measures to control them.
Wastes include defects, overproduction, waiting, inventory, moving, motion, excess processing, and non-utilised talent.
PERT: Programming evaluation and review technique.
Project Evaluation and Review Techniques is commonly abbreviated to PERT. PERT is a method of analyzing the tasks involved in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project. It incorporates uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities. It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in projects where time is the major factor rather than cost. It is applied to very large-scale, one-time, complex, non-routine infrastructure and Research and Development projects.
