market requirements and operations performance

Information for improvement
• The urgency, direction and priorities of improvement
will be determined partly by whether the current
performance of an operation is judged to be good, bad
or indifferent.
• Performance measurement is the process of
quantifying action
• Without performance measurement, it would be
impossible to exert any control over an operation on an
ongoing basis.

Types of benchmarking
• Internal benchmarking is a comparison between operations or parts of
operations which are within the same total organization.
• External benchmarking is a comparison between an operation and other
operations which are part of a different organization.
• Non-competitive benchmarking is benchmarking against external
organizations which do not compete directly in the same markets.
• Competitive benchmarking is a comparison directly between competitors
in the same, or similar, markets.
• Performance benchmarking is a comparison between the levels of
achieved performance in different operations.
• Practice benchmarking is a comparison between an organization’s
operations practices, or way of doing things, and those adopted by
another operation.

20.22
Improvement culture
An organization’s ability to improve its operations performance depends
to a large extent on its ‘culture’ (i.e. ‘the pattern of shared basic
assumptions … that have worked well enough to be considered valid…’
or as some put it, ‘the way we do things around here’.
The elements of organizational culture include:
• the organization’s mission and values;
• its control systems;
• its organizational structures, hierarchies, and processes;
• its power structures;
• its symbols, logos and designs including its symbols of power;
• its rituals, meetings and routines;
• its stories and myths that develop about people and events.
