4. What is Quality?
“Quality is fitness for use” – Deming
In an organization, Quality function means the department which independently works
on attaining specified levels of product / process quality of the core business
Quality Department can either be a quality control department or a Quality Assurance
department
Quality Department is the final In-Charge of the quality at the customer’s end
Quality Control Quality Assurance
Focus on Product Focus on Processes
Analysis after Completion of work Prevention is better than cure
Operation specific Core value; Organisation-wide
Individual/department oriented Leads to team work

7. Quality Plan
All the five major aspects are covered in the Quality plan Document in
the following manner:
Specification for Raw Materials and Parameter to be checked upon receipts
Critical To Quality (CTQ) parameters of machine settings or intermediate products and
checking or verification points
Final product specifications and parameters to be tested for the conformance to customers’
requirements.
Sampling and Testing methods along with the action to be taken in case of any deviation for
all the above
In a nutshell, the quality plan describes how the quality of product /
process is managed in an organization.

8. Quality Plan - Example
Let us assume the Customer requirement is metal sheets for fabrication which
measures 10 x 5 inch metal plate in Green color with two holes
Upon accepting the Purchase order from the customer, the company works on
defining the product requirements as per the internal understanding. This
becomes the product specification and the target output quality.
The customer requirement of 10 x 5 inch metal plate in Green color has
translated in to:
MS / SS / Aluminium sheet of
252 mm length,126 mm width and 0.4 mm thickness (not given in the product requirement and
developed internally based on factors such as strength, pricing, etc)
Powder coated with Green color of Standard Color (with code - abcd) with
Two holes of 2 mm diameter as per the drawing
Copyright of Hash Management Services LLP www.businessense.in
9. Drawing based on the customer requirement
252 +/- 2 mm
62 +/- 1 mm
126 +/- 2 mm
2 mm dia
10 mm
Color Code : Green (abcd)
Copyright of Hash Management Services LLP www.businessense.in
10. Internal Specification
This final requirement/drawing is worked backward - the internal requirements
needed are listed and those become our in-process specifications.
At Painting Section, Painting Color (abcd) and the coat thickness are internal
parameters.
At Cutting section, Size specifications are –
L : 256 +/- 2 mm
W : 130 +/- 2 mm (4 mm extension is made for bending)
The holes as per the drawing
For inward inspection, the sheet thickness, dimensions and paint color forms a
specification

12. Quality Management System - QMS
A quality management system is a set of co-ordinated
activities to direct and control an organisation ensuring
that the organisation is continually improving its
performance.
Quality Plan is an integrated component in the Quality Management System
A QMS enables an organisation to achieve the goals and objectives set out in
its policy and strategy.
It provides consistency and satisfaction in terms of methods, materials,
equipment, etc, and interacts with all activities of the organisation, beginning
with the identification of customer requirements and ending with their
satisfaction, at every transaction interface.
It can be envisaged as a “wedge” that both holds the gains achieved along the
quality journey, and prevents good practices from slipping
Copyright of Hash Management Services LLP www.businessense.in
13. Quality Management System
Benefits of QMS
Improved business planning
Enhanced awareness on quality throughout the organisation
Improved Customer Satisfaction
Reduced cost of poor quality
Above all, an effective QMS provides the confidence to both the organisation
and its customers that the organisation can provide good quality of product /
service consistently.
If the Quality Management System of a company is inline with the set
requirements of ISO 9001, the company may be certified as a quality assured
company by a certification agency and the company will be declared an ISO
9001 certified company.
