Operations and process
management,
• All
operations
processes.
are
composed
of
• A process is an arrangement of resources
and activities that transform inputs into
outputs that satisfy (internal or external)
customer needs.
• The process technology is the methods,
procedures, and equipment used to
transform materials or inputs into
products or services.

• The difference between operations and processes is one of
scale, and there fore complexity.
• Both transform inputs into outputs but processes are the
smaller version. They are the component parts – the
building blocks – of an operation.
• So, ‘operations and process management’, is the term we
use to encompass the management of all types of
operation,
• The general truth is that processes are everywhere, and all
managers
have
something
to
learn
from
studying
operations and process management.

operations and process
decisions
1. Directing the overall strategy of the operation. A general
understanding of operations and processes and their
strategic purpose, together with an appreciation of how
strategic purpose is translated into reality through how
innovation is incorporated into products and services and
how much of the total value-adding process should be
kept in-house and how much outsourced.
2. Designing the operation’s processes. Design is the activity
of determining the physical form, shape and composition
of operations and processes, together with the type of
resources they contain.

3. Planning and control process delivery. After
being designed, the delivery of products and
services from suppliers and through the total
operation to customers must be planned and
controlled.
4. Developing process performance. Increasingly, it
is recognized that operations, or any process
managers cannot simply routinely deliver
products and services in the same way
