The design of control systems is a specific example of engineering design. The goal of control engineering design is to obtain the configuration, specifications, and identification of the key parameters of a proposed system to meet an actual need.
The Twelve Step Process of Designing Control
System
The
ultimate idea of the control system would be to enable one to perform the steps
is shown as the DMAIC process in diagram.
The DMAIC Process
Step 1
The
first step in the process of designing control systems is to attentively hear
the client’s needs. Active listening, effective questioning, conceptualization
of vague situations, and clarifying are first necessary steps in any type of
consultancy task and any consultancy style. Also suspend your judgment so that
you can take in the views freely without your own personal bias. Make notes
carefully.
Step 2
The next
step is to attempt to mentally it the whole project in a holistic framework or
sectional framework or with a zero based approach,as if what currently exists
either needs to be ignored, or it should improve the present situation.
While it
would be useful to mentally size up the holistic goals of the organization, it
may make the project more tractable if only a pragmatic partial issue is
tackled right way. As Martin Kenneth Starr, the systems theorist mentions, it
would be quite legitimate for parts of the system to be taken up for
independent study and design as together they make the problem too complex.
At this
stage, we need to decide the style we would like to adopt:
That of
an expert, used specially by IT consultants who tell what to do based on their
experience
The
helping model, to develop alternate approaches for the consideration of the
organization
The
choice of the model depends on the status, knowledge, and reputation of the
consultant and the attitude of the client, as well as on whether it is an
operational consultancy, process consultancy or a financial consultancy, any of
which a consultancy can be. Tom Lambert asks somewhat analogously for an early
decision as to whether one will be an advocate, an expert, a trainer or an
educator.
A
student doing a summer project would function more effectively if he were
deliberately more modest and chose to adopt the helping model. Those who took a
more aggressive stance have most often fallen foul of the organisations.
Step 3
The next
step is to clearly frame the objectives of the exercise. There should not be
any commitment on the means to achieve the objectives. This is the stage at
which one should have an understanding of the formal as well as the implied
‘strategy’ of the organisation, which is often hiddenfrom the consciousness of
its members and has to be ferreted out and clarified.
Step 4
Step 4
should be a workshop in which a conversational style should be encouraged and
the persons at all hierarchical levels are encouraged to speak out on the
objectives and the means to achieve them. Do not express your own views too
soon as it inhibits free thinking by others and will further have your own bias
in it.
Step 5
Form the
database and make a chart of flow of transactions. Suitable computer software
for this is available and should be used profitably.
Step 6
Identify
critical indicators and compare it with the advice obtained earlier at step
four.
Step 7
Decide
on the measurement and, or observational methods of inputs and outputs.
Step 8
Analyse
the data with reference to these measurements and observations.
Step 9
Discuss
the findings.
Step 10
Prepare
a draft report with alternative remedies and discuss.
Step 11
Redraft
the report.
Step 12
Submit
final report to the management.
Future of Management Control Systems
As
organizations mature and as environments change, managers must expand and
refine their management control tools. The management control techniques that
were quite satisfactory 10 or 20 years ago may not be adequate for many
organizations today.
A
changing environment often means that organizations must set different goals or
key success factors. Different goals create different actions and related
targets as well as different benchmarks for evaluating performance. Obviously,
the management control system must evolve, too, or the organization may not
manage its resources effectively of efficiently. Certain management control
principles that will always be important or that can guide the redesign of
systems to meet new management needs follows.
Always
expect that individuals will be pulled in the direction of their own
self-interest. You may be pleasantly surprised that some individuals will act
selflessly, but management control systems should be designed to take advantage
of more typical human behaviour. Be aware that self-interest may be perceived
differently in different cultures.
Design
incentives so that individuals who pursue their own self-interest are also
achieving the organization’s objectives. If there are multiple objectives as in
usually the case), then multiple incentives are appropriate. Do not
underestimate the difficulty of balancing these incentives-some experimentation
may be necessary to achieve multiple objectives.
Evaluate actual
performance based on
expected or plannedperformance, revised, if possible, for
actual output achieved. The concept of flexible budgeting can be applied to
most goals and actions, both financial and non financial.
Consider
non financial performance to be just as important as financial performance. In
the short run the manager may be able to generate good financial performance
while neglecting non financial performance, but it is not likely over a longer
haul.
Array
performance measures across the entire value chain of the company. This ensures
that all activities that are critical to the long run success of the company
are integrated into the management control system.
Periodically
review the success of the management control system. Are goals being met? Does
success in accomplishing an action mean that goals are being met, too? Do
individuals have, understood, and use the management control information
effectively?
