ABSTRACT
The fierce competition, the economic weakness and the openness that Iraq is going
through on international construction companies have put great pressure on the local
construction companies to develop their performance continuously. Most of the
researchers focused on measuring the performance and success of construction
projects, but a limited number of studies were done on performance measurement at
the level of the construction company, but these studies began to increase due to the
need for performance measures at the companies' level. Key Performance Indicators
are considered one of means for measuring performance and progress towards
objectives of the organization and help organizations and agencies to identify and
measure their progress toward specific objectives. The indicators are weights and
measures derived from strategic objectives through the translation of those objectives
into programs, procedures, and activities. Performance measurement includes four
operations, which are building standards, then assessment then evaluation and then
optimization. Key performance indicators KPIs typically have financial and non-
financial metrics, which is one of the success measurement techniques of the
performance of organizations. Organizations look to the performance indicators as a
strategy to achieve the objectives and results, and a strong indicator of the
organizational success. List of 58 KPIs in five perspectives (financial, customer, social
and environmental, internal business, and learning and growth) obtained from the
previous studies. Then, the questionnaire was developed for data collection to find the
most important KPIs for construction companies in Iraq. The results of the
questionnaire extracted 26 KPIs. The KPIs from the first questionnaire were included
in a second pairwise comparison questionnaire using the fuzzy analytic hierarchy
process (FAHP) technique to obtain the weights related to each KPIs. Finally, the study
obtained 15 KPIs for construction companies in Iraq divided into four perspectives,
financial, customer, internal business, and learning and growth.

1. INTRODUCTION
High competitiveness and profound changes in the construction industry force executives to
continually improve the performance of their companies [1]. According to Luu 2008
performance measurement is the core of continuous improvement, application of the
measurement process within companies can identify strengths and weaknesses in performance
and thus use lessons learned to identify best practices that can lead to an outstanding
performance in the case of its adoption and implementation[2].
In order to measure performance, it is essential to select the appropriate key performance
indicators that are most important in determining the success of the construction process. Its
play an essential role in providing information on the performance of the construction tasks,
projects, and companies.
Many studies were conducted to identify the key performance indicators, most of which
focused on performance measurement at the project level, while studies at the company level
were limited[1].
In Iraq, few efforts to identify indicators that can be used to measure the performance of
construction projects carried out and did not focused on the performance of companies wholly
where interest only financial indicators. Thus the set of balanced performance indicators that
can be used to measure the organization's performance is non-existent. Therefore to fill this
gap, this research aims to identify the most critical performance indicators that can be used by
managers to measure the performance of construction companies in Iraq.
2. LITERATURE REVIEW
The literature review considered two specific subjects, construction company performance and
the importance of key performance indicators in the construction companies. Neely 1995
defined performance measurement as: ‘‘the process of quantifying effectiveness and efficiency
of actions.’’[3]. The previous studies addressed several aspects of construction companies'
performance, such as financial, process, customer, learning, and environmental, etc., by
adopting different approaches [4]. National Institute for Standards and Technology (NIST)
2018 defined indicators as: "numerical information used to quantify the input, output and
performance dimensions of processes, products, programs, projects, services and the overall
outcomes of an organization"[5]. The concept of (KPIs) generated an ever growing number of
indicators because each organization will choose the indicators that support the activities which
are critical and of best value for the organization[6]. To measure the performance of a company,
the first thing to do is to look for the Key Performance Indicators (KPIs). Measurement is the
heart of the performance management process as the information system[7]. Adhiprasangga
2016 confirmed that the first step to use the balanced scorecards is identifying the KPIs of the
company[8]. The creators of the balanced scorecards (BSC), Kaplan and Norton, began their
studies on the subject in the 80s, and published it in their article: "The BSC" of the Harvard
Business Review (1992), where they define the BSC as: "A set of indicators that provide top
management with a comprehensive view of the business." Over time, and to the extent that the
BSC is imposed on more organizations, it has become a comprehensive management system

articulated with strategic planning[9]. Ali et.al. 2013 developed 10 key performance indicators
for construction companies in Saudi Arabia[1]. The authors found that the company
performance did not depend on the financial indicators only but also the non-financial
indicators. Yu 2007 developed a framework to evaluate the company performance[10]. The
author stressed on the need to develop an integrated method to measure the performance of the
project and the performance of the company simultaneously, because the construction industry
oriented towards the project.
3. METHODOLOGY
To identify the key performance indicators (KPIs) for public construction companies in Iraq,
we determines the KPIs from the literature studies to extract the initial KPIs list that related to
the construction companies. Also, personal interviews with the head or deputy of planning and
monitoring department or quality section manager because they are the most related to
performance measurement of the company. The interviews were made to identify the method
used to measure the performance of the company. Then, from the previous studies and
interviews, the first questionnaire was defined and finalized after the judgment of external
experts. The questionnaire has been distributed to experienced engineers working for the public
construction companies which related to the ministry of Construction, Housing, and
Municipalities. After that, the questionnaire was analyzed to find the KPIs with high
importance according to the relative mean of data collected. The important KPIs from the last
step has been included in the second questionnaire form for pair-wise comparison using the
fuzzy analytic hierarchy process (FAHP) approach to find the relative weight for each
perspective and each KPI. Taking in consideration checking the consistency ratio for the
medium and, lower and upper values of integrated comparison matrices which must be less
than 10%. Finally, identifying the metric for each KPI to measure it. These metrics will help to
Measure the performance of the company toward the objectives on periodical intervals. The
methodology steps is shown in (Figure 1).
3.1 Criteria Selection
The primary data collected from the previous studies in order to find the initial set of KPIs.
These KPIs were included in the first questionnaire to identify the relative importance of each
of them.
An interview is an essential tool in academic and scientific research. Therefore, we did
personal interviews with the head or deputy of planning and monitoring department or the
manager of a quality section of the public construction companies.
Interviews showed that there is a performance evaluation in the companies, but it is not
applied conscientiously, and the evaluation used routinely for employee promotion only.

3.2 Questionnaire
To determine the relative importance of performance indicators for construction companies,
we designed questionnaire form to collect the data. 88 questionnaires were distributed to
experienced engineers and number of heads of departments in 8 public construction contracting
companies (Table 1).
From the 88 forms, returned 84 forms. Also we canceled three forms due to incomplete
information and mistakes. Therefore, the number of questionnaires analyzed were 81 which
represent 92% of questionnaires distributed.
The questionnaires categorized into two parts: the first part is the personal information of
the participant where the second part contains the questions to identify the importance of KPIs
proposed.

Reliability of the scale is the extent to which the scale to give results close to each time it
is used, and the reliability of the questionnaire is measured in many different ways. We used
Guttman Split-Half Reliability coefficient and Cronbach's alpha coefficient.
The Guttman coefficient between the two split halves is 0.97, and this means excellent
stability of the questionnaire. Also, by using the alpha equation for the internal consistency of
the questionnaire, had obtained a scale (0.967) for the KPIs group and this mean high internal
consistency of the questionnaire.
The result will take a value from the range (1 to 5) due to the use of a five-point Likert
scale. The calculation has been done using Statistical Package for the Social Sciences (SPSS)
and Microsoft Excel spreadsheets.
After completion of the analysis, the KPIs with relative importance equal or greater than
4.00 were selected from each perspective to evaluate it with the fuzzy AHP pair-wise
comparisons to find the relative weight for each perspective and KPI. Therefore, the selected
KPIs with relative mean are shown in (Table 2) arranged by perspective in descending order.

3.3 Fuzzy analytic hierarchy process technique
Analytical hierarchy process (AHP) is a powerful decision-making methodology developed by
Saaty in the 1980s to simplify the decision-making process [11]. It includes qualitative and
quantitative techniques and makes it possible to decompose complex problems into simpler
sub-problems where each level shows a set of objectives or criteria relative to each sub-group
[11][12][13]. The nine-point scale simplifies the choice of criteria and provides information
regarding the dominance of each element over others concerning the importance of each
criterion of the higher levels of the hierarchy. Individual opinions of view are made in groups,
taking into account the pertinent decision maker and are handled as a foundation for the
analysis of the reasons for specific judgments; there is the one week spot that occurs during the
setup of comparisons matrixes [14][15]. When the number of characteristics is increasing in
the hierarchy, more matchings' between attributes need to be applied.
Furthermore, by increasing of criteria and sub/criteria, the experts are dealing with physical
and mental fatigue. As a result, the judgments are becoming unreliable, subjective and
imprecise. Therefore, the fuzzy triangular numbers is a valuable solution for handling the
subjective and inaccurate judgments. Zadeh developed the fuzzy set theory and had become a
critical methodology in pair-wise comparisons. The fuzzy number can be defined as triple M=
(l, m, u) where its membership function was defined as[16]:
����� = � �� − � , � ∈ �, ��,��� − ��� , � ∈ ��, ��,�, ���������, (1)
Where l ≤ m ≤u, l and u are lower and upper values, m is middle value of M. When all three
numbers are equal (l = m = u), then we are dealing with non-fuzzy numbers. The pairwise
comparisons linguistic scale used is shown in (Table 3):

Figure 3 The hierarchy tree for pair-wise comparison
During the first step, the comparison on the first level between the main criteria
(Perspectives) was established. On the second level, the pair-wise comparison between sub-
criteria (KPIs) was performed. The pair-wise comparison was made by the expert group of 34
members who have over 15-years' experience in the field of planning and monitoring in the
construction companies.
3.3.1. The FAHP calculation of consistency ratio
We must be sure of the harmonic of the comparisons of every participant, to identify if the
comparisons are harmonic or assonant to be confident of the consistency and validity of sample
answers, Gogus and Boucher (1998) method is used to calculate the consistency ratio[17]. The
calculation completed using the procedure below:
Step 1: divide the integrated fuzzy triangular matrix into two matrices, the first matrix for
middle numbers and the second matrix resulted from the geometric mean of upper values and
lower values of triangular numbers.
Step 2: the vector weight is computed using Saaty method through the equations (2) and
(3) below: �� = ����� ����� ��� = �� ∑ ����∑ ������ ���!� (2)
�" = #��"$ ����� ��" = �� ∑ %����∗���∑ %����∗����� ���!� (3)
Step 3: the largest eigenvalue for each matrix is calculated using the equations (4) and (5)
as follows: '���� = �� ∑ ∑ �������� ���⁄ � ��!���!� (4)
Using the Fuzzy-Ahp Technique for Determining the Key Performance Indicators of
Public Construction Companies in Iraq
http://www.iaeme.com/IJCIET/index.asp 1439 [email protected]
'���" = �� ∑ ∑ %���� ∗ ��� )��" ��"* +��!���!� (5)
Step 4: Following Saaty's procedure, consistency indices (CI), which represent the
deviation from perfect consistency, are calculated using the equations (6) and (7) below: ,-� = �'���� ������ (6)
,-" = .'���" �/���� (7)
Step 5: The ratio of consistency index to the average random index shown in (Table 4)
is called the consistency ratio as presented in equation (8), Following Saaty's rule[11][18],
a consistency ratio of 0.1 or less is considered acceptable for each matrix type. If the
consistency ratio of a pair-wise comparison matrix is greater than 0.1, then the participants
should be encouraged to re-evaluate their preferences. ,0 = ,-0- (8)

8 1.3410 0.4164
The FAHP calculation of consistency ratio was done using the programs proposed by Al-
dhaheri 2018 depending on Gogus and Boucher 1998 method[17][20]. After computing the
weights for each perspective and each KPI, the consistency ratios calculated for the new fuzzy
integration matrices. The results for the main matrix (perspectives) and sub-matrices (KPIs)
are shown in (Table 5). All the matrices achieved a permissible consistency ratio under 0.1.

3.3.2. The FAHP Priority Weights and Ranking of perspectives and key performance
indicators
As well, to obtain the priority weights of the perspectives and KPIs, the program proposed by
Al-dhaheri 2018 depending on Chang 1996 is used[16][20]. The relative weights and rank of
each perspective are shown in (Table 6):
Table 6 The relative weights and rank of each perspective
No. Perspective Weight Rank
1 Financial Perspective 0.413 1
2 Customer Perspective 0.180 3
3 Social and environment Perspective 0.000
4 Internal Business Perspective 0.237 2
5 Learning and Growth Perspective 0.170 4
As seen, the social and environment perspective obtain 0.000 weight which means that the
majority of experts opinion that this perspective does not affect the overall performance of the
construction company. The financial perspective obtains the highest weight with 0.413 due to
its high effect on the success of the company.
The results of relative weights and rank of financial KPIs are shown in (Table 7):
Table 7 The relative weights and rank of the financial KPIs
No. Financial KPI Weight Rank
1 Profitability 0.578 1
2 Financial stability 0.000
3 Cash flow 0.218 2
4 Completion within Budget 0.204 3
5 Capital 0.000
It is noted that the profitability has the highest effect on the financial perspective with 0.578.
Also, the experts decided that the financial stability and capital have 0.000 weight and this due
to that these companies are public supported by the government.
The relative weights and rank of customer KPIs are shown in (Table 8):
Table 8 The relative weights and rank of the customer KPIs
No. Customer KPI Weight Rank
1 Quality of service and work 0.438 1
2 Competitive price 0.052 4
3 External customer satisfaction 0.289 2
4 Internal customer satisfaction 0.189 3
5 Market share 0.032 5
It is evident that the Quality of service and work obtained the highest importance with 0.438
weight followed by the external customer satisfaction with 0.289 weight, which proves that
there is great importance to satisfy the customer to increase the performance of the company.
Although social and environmental indicators will not be adopted because the perspective
weights zero, the results of the pair-wise comparison between them will be explained in (Table
9) to identify the preferences of experts if the social and environment perspective is studied
alone.

No. Social and environment KPI Weight Rank
1 Policy or law of government 0.575 1
2 Risk control 0.425 2
3 Competitors 0.000
The experts consider that the competitors have no importance in comparison with policy or
law of government, and risk control to the social and environment perspective.
The relative weights and rank of internal business KPIs are illustrated in (Table 10), which
shows that the business efficiency is the highest in weight (0.227) followed by the effectiveness
of planning with 0.211 weight:

5 Meet pre-set targets 0.027 6
6 Effectiveness of planning 0.211 2
7 Safety 0.176 3
8 Quality control 0.171 4
The relative weights and rank of learning and growth KPIs is shown in (Table 11), which
shows that the motivation is the highest importance with 0.370 weight followed by reputation
with 0.284 weight:

5 Human resource training and development 0.172 4
4. RESULTS ANALYSIS
Kaplan and Norton 1998 mentioned that the number of KPIs is 15-20 for the company[21],
while Ali 2013 stated that the suitable amount of KPIs is 8-12 [1]; also Yu 2007 identified 16
KPIs from 26 KPIs to apply it on construction companies[10]. Alarcon 2001 said that the
implementation of a performance measurement system (PMS) should begin with relatively few
KPIs[22], while Costa 2004 mentioned that high number of KPIs prevents the smooth
application of PMS[23]. Therefore, the KPIs with relative weight equal to or less than 0.100 is
not considered, and the relative weights for the remaining KPIs in the same perspective re-
normalized by sum the remaining KPIs and divide each KPI weight on the sum to obtain the
normalized weight in 100 percent. The final weights for the obtained 15 KPIs are presented in
(Table 12).
Ali S. Tofan and Hatem K. Breesam

In conclusion, these 15 KPIs can be used to measure the performance of the construction
companies in Iraq.
4.1. KPI metrics
After determining the set of key performance indicators (KPIs) and the weights of each KPI
and perspective, these KPIs divided as explained on the perspectives to conclude the
mathematical equation that measures the performance of the construction company in a specific
period.
The weight for each KPI is obtained from the experts by the fuzzy analytic hierarchy
process (FAHP). (Table 13) illustrate the weights and measures of each KPI. The measures
obtained from the previous researches on this field.

After measuring each KPI, the progress toward targets then calculated using the linear
equations below:
1. When the trend of KPI is upward: U��V�����W� = X��"�� − YU-X��"�� − Z������
2. When the trend of KPI is downward: U��V�����W� = YU- − X��"��Z������ − X��"��
Furthermore, the Absolute performance is calculated by multiplying the performance by
the weight as shown below: [\����� ]��V�����W� = ]��V�����W� ∗ ���"��

Moreover, to find the performance of each perspective, the related KPIs absolute
performance are summed and multiplied by weight of perspective to find the perspective
absolute performance.
Finally, the total performance resulted from the summation of the perspectives absolute
performances.
5. CONCLUSION
After the study of hypotheses and the results analysis of the questionnaire and interviews
conducted, where the goal of this study is to develop the key performance indicators to measure
the performance of public construction companies in Iraq, where these indicators were divided
into four perspectives based on the Balanced Scorecard framework. We found that most
companies focus on financial indicators to measure its performance while other indicators were
neglected. We concluded that the financial indicators have the highest impact on the
performance of the construction companies. However, the financial indicators not reflect the
complete picture of the company's performance. It is worth mentioning that the four
perspectives are not separate from each other, where each affects the other, as by increasing
learning and growth indicators, this will lead to an improvement in the internal business
indicators, which in turn will improve the service provided to the customer and thus increase
his satisfaction, which will eventually increase Company profits,
The paper result can be considered as the first step to create an integrated framework to measure
the performance of construction industry in Iraq.
