1. Introduction
The construction industry plays a vital role in the development of the country. It has the potential to boost the economy of the country and creates employment opportunities as well [
1]. It uses laborers and skilled professionals to deliver a project within the specified time and within the budget allocated to satisfy the client or customer [
2].
The construction industry is purely a project-based industry and a project is temporary in nature [
3]. A construction firm can get the competitive edge based on in its performance in the market [
4]. The three major participants are Client (Owner), Contractor and the Consultant, and the relationship among them is temporary and fragile [
5]. A construction project, therefore, involves teams of the Client, Contractor and the Consultants. Construction project teams communicate to exchange information from each other [
6]. The information could be financial or technical. Changes to drawings, specifications, and design and progress status are the key elements to communicate among project teams [
7]. Effective communication is needed to deliver a project on time. On the other hand, miscommunication leads to failure in achieving objectives of a project [
8]. The project teams work with each other and they depend on each other, which may lead to conflicts [
9]. Conflicts in projects make it difficult to achieve project objectives and may lead to failure [
10]. Conflicts arise in projects over resources, duties, tasks, work hours, incentives, etc. It is the responsibility of project manager to resolve the conflict without any time delays to prevent the project failure. Success of a construction project is a widely discussed topic, even today, and there exists a difference of opinion in this regard. Since, the inception of project management, the success of the project is measured by the iron triangle, i.e., cost, time, scope and quality [
11]. A construction project is successful if it is constructed and operated successfully [
12]. A project, if successful, causes satisfaction of the client [
13].
In the literature, proper communication and co-ordination have been identified as a key factor in success of a project. In [
14,
15], it was found that conflict has an inverse relation with project success. It is also evident from the literature that project success and sustainability seem to fluctuate in the same manner, and there are no significant discrepancies between them [
16,
17]. The relationship between different levels of integration of sustainability and project success is not a simple one. The literature identified nine dimensions of sustainability and six measures of project success [
18]. Another study by [
19] found cases where successful projects were induced by sustainability and also where a sustainable practice did not lead to success. They concluded that there should be other factors influencing a project’s outcome. According to [
20], project success is linked to the project manager’s ethics in business. In fact, the International Project Management Association code explicitly mentions sustainability as one of the professional responsibilities of the project manager, without explicitly linking this to project success.
The existing literature is extensive with regard to communication types, conflict types and project success, but is limited in studying the relationship between them, especially in the case of the construction industry. Secondly, the norms, culture, diversity and operating procedures affect the governing rules and regulations of the construction industry of any country, so the impact could be case specific. Hence, it is important to investigate them and formulate a better policy for practitioners in the construction industry. The above section presented a brief introduction of the problem; in
Section 2, an in-depth review of previous and relevant research works on team communication, team conflict and project success, along with some contradictions and gaps in previous research are discussed.
Section 3 presents a research framework of the study. In
Section 4, empirical findings are discussed. The discussion on results is presented in
Section 5. The conclusion and the managerial implications, along with limitations and future recommendations, are discussed in
Section 6.
4. Results
4.1. Demographic Analysis
For the computation of demographics and reliability, Statistical Package for Social Sciences (SPSS) version 21 was used. The demographic calculations are shown below in
Table 1.
Planning engineers who gave responses were 68 in number, constituting a percentage of 25.5%; project engineers were 64, with a percentage of 24%; project managers were 45, with a percentage of 16.9%; senior managers were 71, with a percentage of 26.6%. Similarly, chief executives and managing directors were 6 and 13 in number, with percentages of 2.2% and 4.9%, respectively. Experience is a critical factor when someone is asked to give a response, as experience is linked to more exposure to the problems being faced. The respondents with experience less than five years were 29, from five to ten years were 55, from ten to fifteen years were 123, from fifteen to twenty years were 26, and above twenty years were 34 in number.
Respondents were asked to write the cost of their last completed projects. The respondents from large organizations completed their last project with a much higher cost. The projects with cost less than fifty million were 47, from fifty to one hundred million were 82, from one hundred to two hundred and fifty million were 47, from two hundred and fifty to four hundred and fifty were 60, and above four hundred and fifty were 31 in number.
4.2. Reliability
To calculate internal consistency, the Cronbach alpha was used. A value greater than 0.7 indicates good constructs [
65]. The values are shown in
Table 2 below.
4.3. Confirmatory Factor Analysis (CFA)
CFA is a theory-driven approach to empirically test the established theory with the help of a questionnaire. SmartPLS (version 3.0) software was used for CFA.
Table 3 below shows the loading (direct) scores. The loading scores of indicators that represent a construct must be greater than the values in other rows under different constructs.
Secondly, an indicator is retained if its direct loading score is greater than 0.7 [
66]. According to [
67], there is maximum allowance of 30% reduction in indicators. The number of items in the questionnaire was previously 50, but 12 were discarded, whereas the maximum allowed was 15 in our case. The discarded items were CW3, CW6, PC1, PC3, PC4, PSS6, PSS7, PSS8, PSS10, PSS11, TC6 and TC7.
The loading scores are also presented in
Figure 2.
4.4. Discriminant Validity
The following
Table 4 represents the results of the Fornell and Larcker criterion. The values in diagonal are bolded and they represent the values of the square root of average variance extracted (AVE). If the bold values are greater than the other in the same column, then the discriminant validity is established.
4.5. Testing of Hypotheses
For the testing of the hypotheses, Smart PLS (version 3.0) was used.
4.5.1. Direct Relations
Communication was divided into three dimensions, namely, as formal communication, informal communication and communication willingness. The first three hypotheses were concerned about the impact of communication on project success. The findings are stated in
Table 5.
In
Table 5, H1 states that here exists a relationship between formal communication and project success. The direction of the hypothesis was not mentioned in the hypothesis due to mixed evidence available in the literature. The results indicated a negative relationship and the hypothesis was accepted. H2 states that there exists a relationship between informal communication and project success. The hypothesis was validated, as the
t value is highly significant. H3 states that communication willingness impacts the project success, which was also validated, as the
t value in this case was 1.975, which is greater than 1.65. The hypothesis was accepted with positive impact.
4.5.2. Indirect Relations
Three mediators (task conflict, process conflict and relationship conflict) were used to check the indirect relationship. The results are presented below:
5. Discussion
Construction projects are increasing day by day. Their complexity is also increasing, hence, demanding more expertise and more involvement of people. The developing countries are faced with the problems of lack of facilities such as educational institutes, hospitals, high rise buildings, etc., so construction work is always in continuation. Communication among people is very important and plays an important role in project completion and success. People with different backgrounds, culture, norms and behaviors, interact with each other and, hence, conflict arises. This research was focused on answering the two questions: first, to check and analyze the impact of communication on project success; second, to check the mediating role of conflict on the relationship between communication and project success.
Communication in this paper was divided into three dimensions, i.e., formal communication, informal communication and communication willingness. People involved in projects communicate in different ways. When they communicate through meetings, in office discussions, emails, etc., they communicate formally. When people communicate with each other exchanging information about each other’s background, habits, family, etc., this is referred to as informal communication. According to [
43], communication willingness is basically the will to talk to each other that helps in the sharing of critical data among them and is an important factor that leads to enhanced coordination and trust. The first three hypotheses were concerned about the relationship between communication and project success. The relationship of formal communication with project success was found statistically significant, but the impact was negative (H1). It was because of the reason that, although formal communication enhances coordination among teams or people, it does not help them in developing trust mechanisms and, as a result, the desired project success is not achieved, and differences between them are not resolved by this form of communication [
44,
45].
Informal communication was also found to be statistically significant and positively affecting project success (H2). When people communicate informally, they tend to know more about each other, including about the other’s culture, background, skills, etc., and so conflicts and differences are more likely to be resolved, and project success is achieved, which is also supported by some previous research [
46].
The relationship of communication willingness and project success was also statistically significant and positive (H3). The will to communicate eases the way of information sharing between people, differences are more readily resolved and, as a result, project success is facilitated [
48,
59].
When task conflict was introduced as a mediator between the formal communication and project success, the results were significant. A positive impact was observed, but the mediation was observed to be partial (H4a). The reason is, in task-oriented conflict, people in teams argue and agree or disagree with each other in the ways to accomplish a certain task, which results in an increase in productivity, and project success is achieved. The effect of formal communication is negative on project success, but this effect is lessened by task conflict [
68].
Similarly, when task conflict was used as a mediator between informal communication and project success, the impact was observed to be positive, and mediation was partial (H4b). In informal communication, people tend to know each other, and communication is enhanced. A role is played by task conflict in this regard. With the help of informal communication, people develop trust. So, they argue with each other about the execution or possibilities of execution of a certain tsk and, thus, find different ways to accomplish a certain task, and project success is facilitated [
59].
Communication willingness and project success were mediated by task conflict positively and significantly. Mediation was partial in this case (H4c). When they have a will or intention to talk to each other and know each other, then hesitation is reduced and frankness increases, accomplishing a task becomes easier for them, and the project becomes successful [
68,
69].
When process conflict was introduced as a mediator between formal communication and project success, the negative impact of formal communication was enhanced because of the negative impact of process conflict on the relation. Mediation was observed to be partial (H5a). A difference in opinion about the responsibility of certain tasks or authoritarian issues or assignment of duties is referred to as a process conflict. As discussed previously, formal communication does not remove barriers among team members but, at the same time, if process conflict arises then results are detrimental for project success [
70].
When process conflict is introduced as a mediator between informal communication and project success, the impact is negative with partial mediation (H5b). When process conflict is introduced as a mediator between communication willingness and project success, the impact is negative with partial mediation (H5c). The reason behind this type of conflict damages trust and collaboration among team members and they hesitate or do not bother to talk to each other, and project success suffers [
31,
70].
It is found that relationship conflict has a negative impact on all the direct relations, and mediation is observed to be partial. When relationship conflict was introduced as a mediator between formal communication and project success, the negative impact of formal communication increased due to the relationship conflict as it was also inducing a negative impact (H6a). When people have private or personal quarrels and differences, then they begin to disagree with each other in formal means of communication, and project success is halted [
68].
When informal communication and project success were mediated by relationship conflict, the impact was found to be negative on this positive relation (H6b). This conflict is related to relations among people and, if emotions are hurt, then even informal communication causes conflicts among them. Similarly, the mediating effect of relationship conflict was observed to be negative on the relation of communication willingness and project success (H6c). It is because of the reason that disagreements due to personal differences make them hesitate to communicate freely, and information is not transferred timely, hence, project success is halted [
70].
6. Conclusions and Managerial Implications
In developing countries, construction projects are increasing day by day. However, the construction industry is faced with the problems of miscommunication and conflict. Achieving project success is becoming increasingly difficult with every passing day. The main purpose of this study was to analyze the effect of communication types or dimensions on project success. It has been found that formal communication negatively affects the project success, whereas informal communication and communication willingness have a positive impact. The results of the direct relations of this study revealed and suggested that the project managers and owners of the companies must encourage healthy communication among team members. A communication mechanism must be developed at sites or site offices and must be followed by all teams under the supervision or leadership of the project manager. Official meetings, discussions, and emails are a form of communication, but since these mediums do not enable people to get to know each other, coordination in a task is difficult to achieve. The view of some researchers is that informal communication has a devastating nature on project success, but the empirical results suggested that informal communication enhances trust and coordination, which is also suggested by some researchers. Willingness to communicate must also be encouraged because people tend to know each other, and this is important for the development of trust and coordination, which is important to achieve project success.
When people or team members challenge someone’s authority or refuse to do a task directed by a superior, then not only does the project success suffer, but conflict also arises and member(s) start to quarrel with each other, and the project progress is affected badly and, in some circumstances, the project temporarily stops its progress. Similarly, when team members have differences among themselves over personal issues or personal liking or disliking, then project success is not achieved. It can be concluded that task conflict must be encouraged by the project manager, whereas process and relationship conflict must be avoided to the maximum extent, and a strong conflict resolution mechanism is needed to make projects successful.
These findings can help policymakers, constructors, and marketers to provide proper training and services to improve communication skills of employees to reduce conflicts and achieve project success. This study can also help investors to assess the results of their newly launched projects and provides information on how training can bring change to the attitudes of employees. Furthermore, it explores the main factors involved in raising conflict through different types of communication.
Limitations and Future Recommendations
There are several limitations of this study. First, only professionals from Lahore city were approached. The responses of project managers were relatively lower than the other designated professionals. Respondents from consultants and clients were lesser in number. The model can be tested in other settings and can make a comparison between emerging and developed economies. The introduction of task, process and relationship conflict, as a mediating variable, resulted in partial mediation, indicating the need to introduce some other variables as a mediator in the model, such as contract types and trust among team members, etc.
