2. Introduction
 Specification may refer to an explicit(clear) set
of requirements to be satisfied by a material, design,
product.
 In engineering, manufacturing, and business, it is vital
for suppliers, purchasers, and users of materials, products,
or services to understand and agree upon all requirements.
 A specification is a type of a standard.
 It provides the necessary details about the specific
requirements.
 A product specification does not necessarily prove a
product to be correct or useful.

6. Product Design
 Product design is the creation of objects of
utilitarian(useful) value to people.
 Products are part of immediate surroundings.
 The Product Design involves an understanding of
materials, processes, ergonomics, human behaviour
and systems. Both conceptual thinking, and workshop
and computer skills are essential for the product
designer.

7. System Design
 Systems design is the process of defining and
developing systems to satisfy specified requirement of
the user.
 Systems design could be seen as the
application to product development.

9. Technical information
 Functionality:- The purpose that something is
designed or expected to fulfil.
 Reliability:- The ability of a system or component to
perform its required functions under stated conditions
for a specified period of time.
 Operational conditions:- The condition a technical
device or product is in, when it performs its required
functions.
 Process capability:- To determine the extent to which
the process can meet these expectations.

11. Health and safety issues
 Health and safety policies that relate to work involve
measures taken by employers regarding working
conditions that are aimed creating a healthy and safe
environment for employees.
 The Government sets target regulations for the degree
to which the health and safety of employees at work
should be protected.
