Chapter 6 Flashcards
What is sub-systems?
Within a system there will usually be sub-systems. For example, if a company is a system, then the finance department is a sub-system. Within the finance department will be a sub-sub-system such as the management accounting system, and so on.
What is closed systems?
There are systems that accept no input from the environment, are self-contained and cannot respond to change. These do not exist in business
What is open systems?
These are systems which accept inputs from their environment and provide output to the environment. They react to their environment, e.g. a company
What is objective? (in terms of characteristics of systems)
A system must have an objective to function correctly. For example, a company’s objective might be to maximise shareholder wealth. The objective allows the system to be monitored or controlled.
Wha tis feedback control?
It is defined as the measurement of differences between planned outputs and actual outputs achieved, and the modification of subsequent action and / or plants to achieve future required results. This is the more common type of control system.
What is feedforward control?
it is defined as the forecasting of differences between actual and planned outcomes and the implementation of actions before the event to prevent such differences. E.g. budgeting system: A cash budget might predict that an overdraft will be required in a particular month.
Differentiate between primary, secondary, negative and positive feedbacks.
- Primary feedback - could be reported to line management in the form of control reports, comparing actual and budgeted results. If the variances are small or can be corrected easily, then the information may not be fed back to anyone higher in the organisation.
- Secondary feedback - is where feedback is sent to a higher level in an organisation and can lead to a plan being reviewed and possible changed; for example, the revision of a budget after a large variances were discovered due to price changes over time.
- Negative feedback - is feedback taken to reverse a deviation from standard. This could be by amending the inputs or process so that the system reverts to a steady state; for example, a machine may need to be reset over time to its original settings.
- Positive feedback - is feedback taken to reinforce a deviation from standard. The inputs or process would not be altered.
Differentiate between open loop system and closed loop systems.
- Open loop systems - are where there is scope within the control mechanism for outside involvement; for example, a manager might decide what action should be taken from, say, three options
- Closed loop systems - are where the control action is automatic, for example, the thermostat on a central heating system
Feedback reported to a high level in an organisation that can lead to the revision of a plan is called…?
Secondary feedback
Systems that accept no input from the environment, are self-contained and cannot respond to change are called…?
Closed system
The type of organisational structure where employees have two or more managers is called…?

Differentiate between Management control and Management control systems.
Management control is defined as the process of guiding organisations into viable patterns of activity in a changing environment.
Management control systems are defined as the processes by which managers attempt to ensure that their organisation adapts successfully to its changing environment.
What is a management accounting control systems?
it is an information system that helps managers to make planning and control decisions.
Performance measures for investment centres are:?
ROI; Residual income (RI) and Economic value added (EVA)
ROI for an investment centre is similar to the ROCE for an organisation as a whole. Write down the formula.
ROI = (PBIT / operations management capital employed) x 100
What is residual income? Write down formula
RI is a measure of the profitability of an investment centre after deducting a notional or imputed interest cost. This interest cost is a notional charge for the cost of the capital invested in a division.
RI = Accounting profit - notional interest on capital
Differentiate between Traditional and Modern manufacturing
Traditional manufacturing:
- standardisation of product
- long production runs
- acceptable level of quality
- slow product environment
Modern manufacturing:
- globalisation
- competition
- JIT and TQM
- intelligent machines
