Pugh analysis

Pugh Analysis charts are similar to the pros vs. cons lists. These are used for evaluating multiple options against each other, in relation to a baseline option.The time it takes a development team to analyze the scores and weighting factors is usually much shorter and cheaper compared to deploying the wrong solution to a project. Ranking the criteria further helps focus the team's efforts on the critical few. 

Rather than simply listing the positive and negative aspects of each option, one by one, a matrix of the needs vs. concepts helps address multiple factors at the same time and gives the team a holistic view of the needs vs. alternatives at hand.

 Step by step process of Pugh analysis:

1	Develop a set of criteria based on customer's wants and needs.
2	Enhance these criteria by including any item of functional nature.
3	Develop a group of design concepts that are aimed at satisfying the criteria.
4	Using a simple matrix - list criteria on the left and the concepts across the top. Use simple sketches to illustrate each of these concepts.
5	Select one of the concepts as a baseline.
6	Evaluate each concept against the datum for each of the criteria. Determine whether it is better (+), the same (0) or worse(-) than the baseline. Alternately, one could assign a -1, 0, +1 based on where each choice would stack up against a set of the agreed-to criteria. We could give each of these criterion a weight and get the composite score of the alternate*criterion to determine the better alternative. 7 Record the team's decisions on the matrix. 8 For each column, determine the total number of pluses, minuses and sames. Alternately, take the sum of the alternate score multiplied by weight of the criterion. 9 Work to improve those concepts that scored best by incorporating strong ideas from other concepts. 10 Continue the process of synthesizing concepts.

In the Pugh Analysis winners and losers will become visible at an early stage. The fact that one is forced to carry out a reflected evaluation of each parameter for each of the concepts is very important and is useful to prevent later surprises. Even though obvious losers (or winners) may be found at an early stage, the process requires a continuous elaboration to optimize the concepts.

Executive Summary

This summary is done to show the overall content of the survey on design of chair  preferred by  IIUM students . This survey is done to measure the IIUM students opinion about existing design of chair  in their university. The result will reflect the IIUM  students satisfaction about using chair provided by university and which part of the design of the chair that they like and dislike.

Our focuses include the quality and characteristics of the chair that assist student having lecture comfortably. The questions in the survey are made with attention to design a better chair for university students. It’s straight to the point and it may only need less than 5 minutes for a student to complete the survey questions.

Objectives

1.     To evaluate students’ opinion and satisfaction about chair provided in their university.

2.     To evaluate IIUM students’ preference on design of chair.

3.     To discover characteristics of chair that suitable for university students.

4.     To create new design of chair that can be used in all university.

Methodologies

 Survey is the sample of individuals from a population with a view towards making statistical interference about the population using the sample. Surveys provide important information for all kinds of research fields. Therefore, we are using survey method because we are collecting data information by sample. So we are distributed our instruments which questionnaire to the students through survey. Our survey had been conducted on 50  students of IIUM. The instruments that we use are consisting of 5 demographic questions and 21 questions about chair preferences for the survey purposes and to gather information for data analysis for our findings.

Result & Findings     

Section A –Demographic

Based on our survey on 50 respondents, there are 31 males and 19 females which represent male students as 62% and female students as 38%. Generally, 74% of them are in the age range between 21 to 23 years old, 12% of them are 18 to 20 years old and 14% of them are 24 to 26 years old.
