3. STEPS
Step 1. DEFINE the problem and scope of work of the project team. The
description of the problem should include the pain felt by the customer and/or
business as well as how long the issue has existed. Hence, identify the customer(s),
the project goals, and time frame for completion. The appropriate types of
problems have unlimited scope and scale, from employee problems to issues with
the production process or advertising. Regardless of the type of problem, it should
be systemic—part of an existing, steady-state process wherein the problem is not a
one-time event, but has caused pain for a couple of cycles.
Step 2. MEASURE the performance of current process. Identify what data is
available and from what source. Develop a plan to gather it. Gather the data and
summarize it, telling a story to describe the problem. This usually involves
utilization of graphical tools.
Step 3. ANALYZE the current performance to isolate the problem. Through
analysis (both statistical and qualitatively), begin to formulate and test hypothesis
about the root cause of the problem.
Step 4. IMPROVE the problem by selecting a solution. Based on the identified
root cause(s) in the prior step, directly address the cause with an improvement.
Brainstorm potential solutions, prioritize them based on customer requirements,
make a selection, and test to see if the solution resolves the problem.
Step 5. CONTROL the improved process or product performance to ensure the
target(s) are met. Once the solution has resolved the problem, the improvements
must be standardized and sustained over time. The standard-operating-procedures
may require revision, and a control plan should be put in place to monitor ongoing
performance. The project team transitions the standardized improvements and
sustaining control plan to the process players and closes out the project.
Problem Statement:
Last 3 Years, data shows decline in Placements due to lack of skills and unrevised
syllabus pattern according to the feedback of companies visiting MNIT.
Goal Statement:
Find out the problems and enhance the quality of education in MNIT.

8. Measure Phase
Using MiniTab 17 software bundle we performed Process Capability Analysis. In
this data, we do NOT have Upper Specification Limit (USL) as customer
satisfaction can increase up to any level.

14. Analyze Phase
Here we will find out the special causes of variations and find the relation with
other variables if possible.
In the run chart, we get the relation between average feedback ratings and the
experience of teaching faculty. It can be seen that there are somehow equal
number of ups and downs displayed in the performance. Our target is to improve
the down points and increase the overall performance of teaching staff.

Control Phase
We have set the lower limit to 7 as minimum quality rating found in MNIT teaching faculty.
There are 3 samples (sample no. 2, 8, 16) which are showing performance below lower
specification limit. Removing these points we have the improved chart as follows-

20. Result:
R-chart accounts that the quality of teaching does not only depend on the
experience of teaching a teacher has but on several other factors as well.
Also, the performance of students cannot be judged by their attendance. So MNIT
should not just focus on the attendance of students.
We can also conclude that good infrastructure also helps in enhancing the
education standards.
