# PUGH matrix- Decision Matrix

When PUGH matrix (also called decision matrix) was developed by Stuart Pugh (he was head of design division at the University of Starathclyde in Glasglow, it was primarily developed as a decision model or decision matrix or problem solving matrix. It helps to choose between list of different alternatives. A Pugh matrix is used to Read more about PUGH matrix- Decision Matrix[…]

# Cause and Effect analysis

The cause and effect matrix (also called C & E matrix) helps you decide which inputs from a Cause and Effect  fishbone diagram should be tackled / addressed first. All the causes of the problems from the fishbone diagram may not be of equal value. The Cause and Effect (C & E) matrix provides a Read more about Cause and Effect analysis[…]

# Force Field Analysis

Force field analysis is a tool that helps you to identify the forces help to accomplish the goals and those forces that hinders the attainment of the goals. First developed by social psychologist Kurt Lewin in 1940s, force field analysis is now considered a highly effective tool to make decisions effective and structured so that Read more about Force Field Analysis[…]

# Analytic Hierarchy Process

Originally developed by Prof. Thomas L. Saaty, Analytic Hierarchy Process (AHP) is a method of decision making taking multiple criteria. The good thing about Analytic Hierarchy Process / AHP is it allows some small inconsistency in judgment as no human always make a consistent decision. Suppose you have two products that you want to launch. Read more about Analytic Hierarchy Process[…]

# RACI matrix for teamwork in lean projects !

RACI matrix is a simple way of assigning various tasks and responsibilities to the members of the project so that each task can be done carefully (without repetition) and is accountable with measures to consult in case of troubles. It is used to clarify roles and responsibilities in a cross-functional project amongst various stakeholders (people Read more about RACI matrix for teamwork in lean projects ![…]

# POKA YOKE/Mistake proofing

The name Poka Yoke (in Japanese for mistake proofing) was coined and formalized by Shigeo Shingo in 1960.  This concept was first used in Toyota  to check the occurrence of simple mistakes. Shigeo Shingo used this concept to avoid the workers to miss  assembling the springs in the switches. Consequently, a lot of switches had Read more about POKA YOKE/Mistake proofing[…]

# Monte Carlo Simulation: Uses in Industrial applications

A Pharmaceutical company’s case study: Use of MONTE CARLO SIMULATION as a PROSPECTIVE WAY of improving content uniformity and selection of right excipients! We live in a world full of uncertainty! Often, it’s near impossible to test the efficiency of a product or include all processing parameters in building uniformity in a product by repeating Read more about Monte Carlo Simulation: Uses in Industrial applications[…]

# Pareto Chart and Pareto Analysis

A Pareto chart is an analytical tool which can be used for both Quantitative and Qualitative data. It is based on Pareto analysis developed by Vilfredo Pareto who coined it as an “80/20 rule,” which postulates that roughly speaking, 20 percent of the people own 80 percent of the wealth. Or, in quality terms, 80 Read more about Pareto Chart and Pareto Analysis[…]
