1. Introduction
Value creation in modern organizations is primarily achieved through intangible factors, including intellectual capital (IC), which is based on the so-called knowledge assets. The views and values of the society are being remodeled. Building the competitive advantage of enterprises is determined mainly by intangible resources. Moreover, a significant increase in the importance of project undertakings is observed. According to P. Drucker, following the industrial and production revolutions, currently we are in the third phase of the economic evolution, i.e., the so-called management revolution in which organizations use the resources they possess to create enterprise value, owing to the effective implementation of project tasks [
1,
2]. Taking the above into account, it is important to note that project management in modern organizations revolves around activities directed towards the best use of various IC components, in order to efficiently and effectively achieve the set project objectives [
3,
4]. To this end, it is important not only to understand the relationship between various components of IC and project success, but also to be able to use tools, technologies and concepts that support the use of IC for project purposes. This should lead to synergies resulting from the ability to combine individual IC elements and methodologies to support the project management [
5,
6,
7]. This paper explores the relationship between individual IC resources and project success in the ICT industry.
A success in implementing a project could be possibly derived from the maturity and learning capability of a project team [
8,
9,
10]. In general, a project team consists of a diverse group of individuals, with different backgrounds and experience, and possibly from different functional areas within an organization. With this diversity, an effective project team depends on human learning, which transforms into human capital [
11,
12,
13]. Project management has a special role in industrial management. Project members are often selected from functional departments (production, marketing, and finance). They are expected to work within an ad hoc project which will later be dissolved when a project is completed [
14,
15,
16].
Often, a large functional unit, such as production, is required to continuously improve its performance through a series of project investments, especially in the areas of digital (information and communication) technology. A project team(s) is established to ensure cohesive work. Implementing a project under the member diversity and the business pressure (i.e., timeliness, cost management, and quality and compliance) highlights the need to focus on learning among these members [
17,
18,
19,
20]. This learning capability plays a crucial role in strengthening IC. IC is viewed as one of the competitive advantages in industrial operations and management today [
18,
21,
22,
23,
24,
25,
26].
According to Joslin and Müller [
27,
28,
29], project success (PS) remains a great challenge for managers, given the risk and uncertainty (e.g., complex scope of work, reliance on subcontractors, regulatory compliance, team diversity, etc.). According to a conventional classification of a firm’s assets, resources of an enterprise are usually understood as the physical resources defined as material assets, such as fixed assets, equipment, land and monetary resources (cash and receivables), while key competences include knowledge resources dispersed in an organization, i.e., IC [
30,
31,
32,
33,
34].
IC represents the intangible value of a company which can contribute to its business and operational success [
35,
36]. A high level of IC is deemed to be a potential contributor to high performance, which includes PS [
37,
38]. The issue of the influence of IC on PS is present in recent research in the context of information technology (IT) projects [
39,
40,
41,
42]. The analysis of the results of these studies supports the thesis on a strong correlation existing between IC and PS. It has also been demonstrated that IC has a positive impact on project success and can therefore be a good predictor of future project performance [
43,
44,
45,
46]. More importantly, the authors found an important intermediary role of the structural capital in the application of human and relational capital in project success [
47,
48,
49,
50]. The survey described in this paper goes a step further than what has been achieved so far and shows the dependencies of the constituent components of IC on the individual elements of PS. Ultimately, they also show the overall (in aggregate form) impact of IC on the PS.
The attempt to define IC and to classify its main components (dimensions) is not straightforward. Authors classify the different components depending on the criterion adopted [
51,
52]. The perception of IC has also changed over the years [
53,
54,
55]. There is no universal and comprehensive approach for both classifying and measuring the IC. The approach depends both on the researcher, the nature and the detail of the research conducted, but above all is specific to the industry under study. Based on the extensive literature review as well as the practical experience, the authors have attempted to classify key aspects of IC from the perspective of the ICT industry [
56,
57,
58,
59]. The industry is specific in terms of the IC application. For the purpose of the present study, the classification adopted was the most common approach specifying: human capital, relationship capital (client capital, cooperation capital), organizational capital and structural capital. Human capital consists of the knowledge, skills, and health that people invest in and accumulate throughout their lives, enabling them to realize their potential as productive members of society [
60]. The ‘term human capital’ is often discussed as one of the key components of IC [
12,
32,
34]. Relationship capital is the sum of an organization’s connectivity to the marketplace, both directly and indirectly [
61]. Organizational capital is the information/knowledge embodied in employees [
62]. Structural capital consists of the supportive infrastructure, processes, and databases of the organization that enables the human capital to operate [
63].
2. Materials and Methods
2.1. Research Objective
Due to the significance of project management in operations and despite some adjustment in monitoring the criteria (e.g., satisfaction of team members within a project), the learning capability within a project has been constantly brought up as a possible criterion to help prevent a repeated failure [
64,
65,
66,
67]. Many executives have called for proactive criteria (i.e., more predictive to the future) for project management, as existing criteria are viewed as reactive (i.e., information from the past to the present) [
68,
69,
70,
71].
The primary objectives of the research are to evaluate the suitability of IC as a possible monitoring criterion for project management and the interrelationships between IC and a PS. The consideration into IC is based on the importance of a speed of human learning in a complex business environment during the implementation of a project remains a challenge for many manufacturing and service firms, especially when dealing with project investments to increase their long-term competitiveness [
35,
72]. In addition, the recent trend on the shortened project duration renews the need to examine the roles of IC in project management [
73,
74]. IC consists of human capital, relational capital, and organizational capital [
75,
76,
77]. It should be noted that the significant number of studies focuses on demonstrating the relationship between intellectual capital commonly understood and the success of project ventures [
61,
78,
79,
80,
81,
82]. The relationship between IC and its dimensions and the various elements of an organization’s success (performance) is not a frequent subject of research and scientific analysis [
83,
84,
85]. Consequently, the primary objective of this paper is, first of all, an attempt to show partial (individual) dependencies between individual IC and PS components and further in an aggregated form, as well as building a model that identifies those elements of the IC that are of crucial importance to project success. On the basis of the identified research problem, the following main research hypothesis was developed:
Hypothesis 1 (H1). A relationship exists between intellectual capital and project success [the successful implementation of a project].
In order to make the main hypothesis more detailed and the conducted survey more comprehensive, two supporting hypotheses were formulated:
Hypothesis 1.1 (H1.1). Significant interdependencies exist between IC components and PS components.
Hypothesis 1.2 (H1.2). Choosing the right configuration of IC components is the key condition for successful project completion.
2.2. Data and Methods
The methodology consists of the development of a questionnaire, the analysis and interpretation of the results, and the discussion with the research’s implications. In this study, a questionnaire with the 5-point Likert scale was to be developed to help identify possible key factors of PS from the viewpoint of IC. This scale is a bipolar interval scale which allows to measure attitude and belief of the participants. For the scale’s interpretation, it is as follows: 1 = strongly disagree, 2 = rather disagree, 3 = neutral, 4 = rather agree, 5 = strongly agree. The questionnaire consists of five sections with a total of 88 questions and 155 variables.
Inference was based on selected descriptive statistics of PS and IC components (mean, median, mode, standard deviation, skewness, kurtosis). Further, for the purpose of the analyses, correlations (Spearman’s rank correlation analysis) between the PS and IC components and between PS and “clustered” IC were applied. Additionally, cross-tabulations and a model-based approach—i.e., multivariate and logistic regression were used.
For each data set, Cronbach’s alpha coefficient (AC) was estimated, testing each time the internal consistency of the survey tool (AC > 0.6). The analyses were based on data obtained directly from a survey (survey data—SurD) and converted to 0–1 form using the formula below (Formula (1); converted data—ConD).
Formula (1) is the general formula for determining the (
) indicator
where:
—set indicator,
—number of elements (considered in the indicator),
—the consecutive number of the response (assessment) analysed,
—the value of the response (assessment), expressed by the respondent for the i-th object forming the indicator,
. The resulting
index was interpreted as follows:
0—means the value of the indicator for the sum of points smaller than 3n—was interpreted as condition unfulfilled,
Inconclusive—means that a value of 0 or 1 cannot be assigned to an indicator for a sum of points equal to 3n,
1—means the value of the indicator for the sum of points above 3n, interpreted as fulfilling the condition.
As a limit of the positive verification of each determined indicator, a middle value was adopted () between the minimum () and maximum () value of the obtained points for each determined indicator, was assumed. The minimum value of possible points determining a given indicator (feature) is a product of the number of responses and the value of 1 (from a five-point Likert scale). The maximum value for a given indicator (feature) is the product of the number of responses and the value of 5 (from the five-point Likert scale).
With the use of the processed data, an attempt was made at developing a model (analysis of logistic regression) of the project success’s dependency on the identified components of intellectual capital. The research and statistical methods adopted, models used, indicators and their interpretations are recommended for management science and qualitology [
86,
87].
2.3. Research Model
This section presents the details of the data collection which consists of the profiles of the companies or enterprises and the participants, and the data analysis. The data analysis primarily focuses on the interrelationships between IC and a PS. The details are as follows. The adopted research model (see
Figure 1) included the stage of defining the research problem and formulating the research objective (Stage I), four intermediate steps related to the implementation of the research (Stage II) and the stage of discussing the results, together with developing application recommendations (Stage III).
In stage two, the first step was to identify the key elements of the PS and the most important components of IC. The second step consisted in collecting, aggregating and validating the data obtained. The results were also interpreted, especially those concerning the assessment of key PS components. The third step was a key research stage in which the verification of the relationship between the PS and IC was performed, using several statistical methods. The fourth and the last step was the interpretation of the results of the conducted survey; particularly the determination of the relations between IC and PS. The effect of this step was a set of developed recommendations for application.
4. Discussion
The survey conducted and the results obtained complement the research gap identified in the literature on the subject of project success, from the perspective of the project success, from the perspective of the application of the intellectual capital. Research to date has mainly focused on demonstrating the overall relationship between project success and an organization’s intellectual capital, with lesser focus on identifying the relationship between the individual components of both success and capital [
19,
74,
89,
90,
91,
92,
93,
94]. The literature review undertaken identifies both the critical factors for the successful implementation and management of the intellectual capital and the key determinants of the success in project ventures, but nevertheless the juxtaposition of these components and the search for intercorrelations shall be a direction for further research. Clearly, based on the findings, a PS could be attributed by the IC. This finding is consistent with the premise of the IC’s potential benefits for operation management [
18,
21,
95,
96].
On the basis of all of the responses provided by respondents (SurD) a comparison (
Figure 2) of PS (vertical axis; range <9, 45>) and IC (horizontal axis; range <27, 135>) was made. The horizontal dividing line (for PS) results from a demarcation value of 27 points, and the set above it represents PS, while the area below illustrates failure. The vertical dividing line (for IC) results from a demarcation value of 81 points, and the set on the left represents the absence of IC, while the area on the right represents the presence of IC.
The scatter chart presents the evident clusters which include: the presence of intellectual capital (IC > 81) and project success (PS > 27) and the absence of intellectual capital (IC < 81) and project failure (PS < 27). Hence, it may serve as evidence that those areas are interrelated.
More importantly,
Table 7 shows the frequency of PS or failure (in %), within the context of a company’s IC. The presence of IC was verified by means of a total of 27 questions (
). The threshold value below which, 0 was assumed (lack of resources), and above which, was 1 (presence of resources was set at 81. PS was also determined using the value after converting the obtained sum of points (0—failure and 1—success). The analysis clearly confirms that the positive perception of IC increases the probability of succeeding in the final project implementation.
In 58% of cases, PS coincided with IC (ConD). Another large group (25%) was the set characterized by the absence of IC and project failure. There are also two additional groups where, with the presence of IC, no [expected] outcome of the project was reported (8%) and also where PS occurred, despite the estimated absence of IC (9%).
An additional set of analyses was also performed for the above chart. All of the results obtained are statistically significant (). The value of the chi-squared test () indicates that there is a relationship between the positive perception of IC by the employees of the company and the success of the project. The ϕ value () and Cramer’s V value () and Spearman’s rank correlation coefficient () prove a significant correlation between the examined elements.
The study also assessed the relationship of the individual IC elements with PS. For this purpose, a logistic regression (backward elimination method: likelihood ratio) were used.
The following components were qualified for the model (): customer retention mechanisms () and IC resource utilization capabilities (). Details of the model are presented in Formula (2).
Formula (2) explains the project success model
The presented model also indicates the project success or failure with a high accuracy (percentage of the total correct qualifications—81.6; see
Table 8).
Conclusion: Having only the aggregate information on the assessment of customer retention mechanisms and IC resource utilization capabilities, it is possible to indicate the project outcome (success or failure) with more than an 80 percent accuracy.
Table 9 presents the calculation of the PS index values depending on the different values of the independent variables. In order for the success value to be greater than the 50% threshold value, it is necessary (value 1) to have customer retention mechanisms (
) in place or IC resource utilization capacity (
).
Based on this model, several conclusions about PS can be drawn.
PS is influenced by customer retention mechanisms, including loyalty programs, framework agreements, etc. The chance of PS in an organization with such mechanisms in place is significantly higher than in an organization without such mechanisms ().
PS is influenced by the organization’s IC resource utilization capabilities. The chance of PS in an organization in which the aforementioned behaviors are present is significantly higher than in an organization in which such behaviors were not found ().
As regards H1.2—it is possible to build models demonstrating the influence of the selected IC elements on PS, which means that choosing the right configuration of IC components is the essential condition for a successful project completion. The conducted analysis indicated two key elements of the IC: customer retention mechanisms, including loyalty programs, and framework agreements resulting in company’s ability (capability) to utilize IC resources. The identified interdependence of customer retention mechanisms result in a nearly 5-fold increase in the probability of success ( and the company’s ability (capability) to utilize IC resources (a nearly 6-fold increase—), have a decisive impact on the success of the tasks performed. In particular, the presence of these two elements increases the probability of PS (by 90%). Therefore, hypothesis H1.2 should be considered confirmed (supported).
Limitations and Future Work
The presented survey allowed for a better understanding of the relationship between the PS factors and the individual assets of IC. It should be clearly stressed that the research was limited to the ICT industry, using purposive sampling and random selection. The arbitrary method of determining the conversion of the data collected by means of questionnaires into the 0–1 form (presence or absence of the factor/effect) can be added to the set of such limitations. For the purpose of the analysis, the delimitation was set at 3n (min. 1n; max. 5n). The determination of the exact point of transition between 0 and 1 could be the subject to further research.
Further analysis could also address the elements that were rated by the respondents the lowest, e.g.,: full achievement of all project goals, components of cooperation capital and organizational capital (also in the context of the absence of statistically significant correlations). Further research could also be aimed at obtaining even more accurate regression models.
It should also be noted that project success was partly assessed on the basis of the perception/view of the respondents, as well as on the basis of the objective project success criteria which can partly be biased and affect the results. However, the respondents were professional project managers holding senior positions in organizations and persons with extensive experience in the companies surveyed, which significantly limits the subjectivity or randomness of their answers.
The authors point out that the classification of the various components of IC depends both on the researcher, the nature and detail of the survey conducted, but above all is contingent on the analyzed industry. The ICT industry is notorious for its specificity in terms of IC. Therefore, the authors adopted the most common IC systematics/classification for ICT, with a proviso that other studies may be based on different characteristics of IC and its components.
Despite the multi-faceted analysis of the issue, the research needs to be continued, especially to cover other industries and business branches. A detailed analysis of the individual cases (case study), mainly covering projects of high complexity and very high budget—the so-called mega-projects—seems to be extremely promising. The conducted research has also highlighted the relatively weak relationship between the scientific and business environment. The analysis of this phenomenon and an attempt to reduce this gap should be a challenge for both the academics and the business community.
5. Conclusions
In conclusion, the positive verification of the supporting hypotheses (H1.1,H1.2), as well as the entire research material and its analyses, allow an unambiguous positive verification of H1, which proves the existence of a strong dependency between intellectual capital and the successful implementation of the project. Its impact was recorded both with reference to the individual success components, and in an aggregate form. It means that IC is an indispensable component (prerequisite) guaranteeing project success.
First, on the basis of the conducted literature research (see Introduction), the key elementary components of PS (nine elements) and IC (16 elements) were identified, and their individual relationships were examined using the Spearman’s rank correlation (see
Table 4). Subsequently, the individual elements of the OI (human capital, client capital, cooperation capital, organizational capital, structural capital) were grouped, and the relationship beteween these grouped elements and the individual PS components was shown (see
Table 5). Then, the relationship of the aggregate IC with the basic PS is shown (see
Table 6). The research results have shown that strong relationships exist between the selected items. The detailed characteristics of the identified dependencies are described in
Section 3.2. Interrelations between IC and PS. The final conclusion is that a relationship between PS and IC depends on the presence (or absence) of IC in the organization. In 58% of cases, PS coincided with IC. Another large group (25%) of cases was the set characterized by the absence of IC and project failure (see
Table 7). The Spearman’s rank correlation coefficient
revealed a significant correlation between the examined (grouped) elements, indicating that the research results are significant. Due to the existence of a significant correlation between PS and IC, an attempt was made to identify the IC elements of the particular relevance to PS. For this purpose, the logistic regression (backward elimination method: likelihood ratio) was used. The conducted analysis indicated two key elements of the IC: customer retention mechanisms, including loyalty programs and framework agreements resulting in a company’s ability (capability) to utilize IC resources. The presence of these two elements increases the probability of the project success’s achievement (by 90%) (see
Table 9).
The detailed results of the study confirm that PS is achieved to a greater extent in the organizations with a high IC (median 37.5 points, mean 34 points) than in those with a low IC (median 17.5 points, mean 24 points). From an opposite perspective, successful projects recorded high levels of IC (median 103 points, mean 95 points). For projects that failed, the median was only 53 points and the mean 62 points (see
Figure 3). In both cases, the data on the vertical axis (SurD) were presented in a cumulative form, whereas on the horizontal axis, ranging from 0 (condition not met) and 1 (condition met) (ConD). Thus, the conducted research confirms the close correlation between IC and PS.
The study of the PS is important for industrial and business operations alike. The impacts of a project’s failure has been well documented (in terms of delays, financial penalty, loss of reputation, etc.). This failure contributes to an organization’s performance and long-term competitiveness. The responses to individual questions through vigorous statistical analyses point to the need to essentially integrate IC into project management (from the planning and design until the implementation stage). This integration is viewed as an important contributor to a PS.
A multidimensional study of PS allowed the final conclusion to be formulated as follows: the use of advanced project management solutions is a necessary but not sufficient prerequisite for PS. A high level of IC supporting project activities is necessary for success. This fact is of particular importance for advanced IT solutions.
