The Performance Measurement in an Operations Environment 1

1. Thesis statement

The present essay will address the topic performance measurement in an

operations environment. The aim pursued by this essay is to describe this activity

from the perspective of its vital importance to the welfare of every enterprise and, its

desired objectives are the followings. Firstly, the contextualisation of the operations

performance measurement; secondly, the establishment of the real importance of

doing the measurement, and finally, the presentation of the productivity approach as a

means to assess operations performance measurement at an operational level.

2. Introduction

The measurement of business operations performance always has been an

important issue for every organisation, either it is for-profit or not and there have been

very different approaches to it over time. In the period between the end of the Second

World War and the year 1980, the focus of the operations managers was mainly

centred on efficiency, which indicates that they were influenced by the situation given

by that time, and that the management paradigm was sales instead of the costumer.

Currently, when organisations are being forced to be quickly adapted to a new

marketplace in an environment of globalisation and internationalisation, the

management paradigm has turned to be centred in competition on the performance

objectives for the operations function which are cost, dependability, flexibility, quality

and speed. (Neely, 2002).

Additionally, in recent years new methods have been developed to address the

performance measurement. In addition, new frameworks have been established

aiming to examine the assessment of business performance such as balance scorecard,

business excellence model, new approaches to productivity measurement, to name

but a few. Moreover, many organisations have become controlled by measurement. It

is obvious when in the past there was just one parameter to assess the level of

accomplishment of certain goal and now there are many of them to measure the same,

this situation might be misleading for the operations manager.

Nowadays, although business performance is extensively studied by people

from different academic fields, there is a lack of knowledge transfer between the fields

due to the fact that the knowledge is just shared among the people within a field;

resulting in an overlapped effort. (Neely, 2002).

In the next section a contextualisation of the topic addressed will be delivered.

3. Contextualisation of the operations performance measurement

To contextualise the concept behind the activity performance measurement in

an operations environment it is necessary to refer to operations management and

operations strategy, the macro-activities in which it is involved.

3.1. Operations Management

Operations, marketing and product/service development are core functions of

any company; The operations is the part of the organisation that creates and/ or

delivers its products and services. (Slack, N., Lewis, M. 2011, p.2). Therefore, all

organisations possess an operations function. The processes and resources of the

company are used by the operations function to fulfil costumers needs, by

transforming inputs into outputs as is proposed by the model input-transformation-

output of operations shown in the figure 3.1.

Operations Management is the activity of managing the resources which are

devoted to the production and delivery of product and services. (Slack, N., Chambers,

S., Johnston, R. 2007, p.25). The activities of the operations management activity

which are usually seen in a broad spectrum of kinds of operations are summarised in

the figure 3.2.

The activities undertaken by the operations management function form a cycle,

which is composed for four of them. Operations strategy is the first activity, the aim of

this activity is to understand the strategic objectives of the operation. Design is the

second activity of the cycle, its responsibilities are basically the design of the

products/service and processes of the company in terms of composition, physical

shape and form. Planning and control is the third activity, its objective is to decide

what the operation resources should be doing, then making sure that they really are

doing it (Slack, N., Chambers, S., Johnston, R. 2007, p.21). Improvement is the fourth

activity; it is concerned with the process of on-going enhancement of the operations

performance.

The operations strategy activity and its relation with the concept of

performance measurement will be stated in the next part.

3.2. Operations strategy

Hayes, et al.(2005, p.33) define operations strategy as a set of goals, policies,

and self-imposed restrictions that together describe how the organisation proposes to

direct and develop all the resources invested in operations so as best fulfil ( and

possibly redefine) its mission.

However, other authors as Slack and Lewis (2011) claim that there is no

agreement on the definition of operations strategy; they suggest that a complete

description should be based in the four perspectives on operations strategy, which are:

- operations resources: operations strategy should build operations capabilities(Slack, N., Lewis, M. 2011, p.11).,

- bottom up: operations strategy should learn from day-to-day experience(Slack, N., Lewis, M. 2011, p.11).,

- market requirements: operations strategy should satisfy the organisationsmarkets (Slack, N., Lewis, M. 2011, p.11) and

- top down: operations strategy should interpret higher-level strategy. (Slack,N., Lewis, M. 2011, p.11).

The third perspective, which is related to the reconciliation between the

markets requirements and the operations resources involve the idea of performance

objectives (quality, speed, dependability, flexibility, cost), those aspects of

performance are pursued by firms to satisfy markets requirements. (Slack, N., Lewis,

M., 2011).

A correct interpretation and translation of the markets requirements into the

performance objectives enables the operations manager to make better decisions,

taking into account the resources, the experience and the alignment necessary with at

the corporate strategy. The importance of the measurement of the performance

objectives achievement level will be discussed in the next section.

4. The importance of the operations performance measurement

The importance of this measurement underlies in the importance that

operations function have for any company.

It is compulsory for every firm to know how the operations function is

performing due to, that an effective and efficient usage of the resources of the

enterprise to satisfy its costumers, can offer different advantages to the business, such

as: it can reduce the costs, it can increase revenue owing to the increment in the

costumer satisfaction, it can reduce the amount of investment necessary to create the

products/services and it can establish the platform for future innovations. (Slack, N.,

Chambers, S., Johnston, R., 2007).

Thus, the operations performance measurement acts as a robust tool for the

operations manager to assess the performance of the operations function. Moreover,

a comprehensive knowledge of the characteristics of the performance might enable

him/her to make the right decisions and deliver correct, important and relevant

information to the managers of the other functions of the firm, to the CEO, to the

executive board and to the subordinates. A methodological approach to the

measurement of the productivity as an assessment of the operations performance at

operational level will be delivered in the next part of the essay.

5. Productivity as an assessment tool of operations performance measurement at

operational level

5.1. Operational Measurements

At operational level a group of three measurements are needed:

- Throughput: the rate at which money is generated by the system throughsales. (Chase, R., Aquilano, N., Jacobs, F. 1998, p.794),

- Inventory: all the money that the system has invested in purchasing thingsintends to sell. (Chase, R., Aquilano, N., Jacobs, F. 1998, p.794) and

- Operating expenses: all the money that the system spends to turn inventoryinto throughput (Chase, R., Aquilano, N., Jacobs, F. 1998, p.794).

Goldratt and Cox (1992) point out that the ultimate goal of a firm is to make

money. Therefore, for a company to achieve its main aim it should pursue the

operational goal, which is to raise the throughput while the operative expenses and

the inventory should be reduced. (Chase, R., Aquilano, N., Jacobs, F., 1998).

Productivity measurements can be used to assess the operational performance,

always taking in to account the variations in throughput, inventory and operating

expenses.

5.2. Productivity

The measurement of the productivity has changed over the time from one

narrow and fractionated to one which is broad an integrated, with its output side

centred on whole products and its input side focused in human resources and

operating cots. (Schonberger, R., Knod, E., 1994).

Slack, et al. (2007) define productivity as the ratio of what is produced by an

operation to what is required to produce it.(ec. 5.1).

(5.1)

Productivity is a relative measure, because of this situation it has to be

compared to be meaningful. The comparison of productivity can be made; firstly,

measuring the productivity rate on the same operation over time and secondly, a

process of productivity benchmarking can take place. (Chase, R., Aquilano, N., Jacobs,F., 1998).

Different measurements of productivity can be made, depending on the impact

of which production factors are desired to be assessed. Thus, there is a partial (ec. 5.2),

a multifactor (ec.5.3) and a total productivity measure (ec.5.4). (Slack, N., Chambers, S.,

Johnston, R., 2007).

6. Conclusion

To sum up, the performance measurement of the operations function in every

company plays an essential role in the management process of the operations and in

the management of the whole firm. Basically the data obtained from the performance

measurement enables the operation manager to make correct decisions aligned with

the corporate strategy. This is with the intention of looking for a better satisfaction of

the customers needs taking into account the resources and the production factors

possessed by the company.

The ultimate goal of the performance measurement is to help in the decision

making process in order to, at the end of the day, turn the operations function into a

source of sustainable competitive advantage for the company to compete successfully

in the current economic climate.
