Project management practices are the fundamental guidelines that should be followed for the effective management of processes, initiatives or projects in organizations. Project management practices have largely been applied by firms to improve their performance, sustainability and competitive advantage. The purpose of the study was to evaluate the influence of project management practices on the competitive advantage of Naivas supermarkets in Mombasa county, Kenya. The study selected Mombasa county since it had experienced poor performance and closure of various convenience stores in the past five years. The study sought to establish the influence of project leadership, project communication, project risk management and teamwork amongst project staff on the competitive advantage of Naivas supermarkets in Mombasa county, Kenya. This study applied a descriptive survey research design. The target population was 112 employees in four branches of the supermarkets in Mombasa county, Kenya. The sample size for this study was 88 employees that were selected using stratified random sampling technique. The study used a structured questionnaire to collect the quantitative data required. Prior to the final data collection, the designed questionnaire was subjected to a pilot test that was conducted on 9 employees of Carrefour supermarket, Mombasa. Data was collected using the drop-and-pick method. The analysis of collected data was done using descriptive statistics including frequencies, percentages, means and standard deviations and regression analysis. The study findings determined that project leadership (β=0.747, t=8.089, p<0.05) project communication (β=0.944, t=10.388, p<0.05), project risk management (β=0.455, t=2.845, p=0.006) and teamwork amongst project staff (β=0.744, t=11.259, p<0.05) all had a significant influence on competitive advantage of Naivas supermarket in Mombasa county. The study concludes that project leadership, teamwork amongst project staff, project communication, and project risk management were all essential project management practices for the competitive advantage of convenience stores in Mombasa county, Kenya. The study recommends to organizations such as retail trade association of Kenya (RETRAK) to ensure that they have a policy that binds organizations in the retail sector into adopting project management practices such as project leadership, teamwork amongst project staff, project risk management and project communication. Moreover, the study makes recommendations to other convenience stores in Mombasa county and also in other parts of the country to adopt project management practices like those adopted by Naivas supermarkets in Mombasa county.

As competition increases in the market place, organizations are seeking ways to remain competitive and relevant (Amarakoon U et al., 2018). Project management practices are the fundamental guidelines that should be followed for the effective management of processes, initiatives or projects in organizations to enable the organization attain its objectives and achieve competitive advantage (Badewi A, 2016). Badewi provides a list of practices of project management that organizations in all sectors adopt to have successful outcomes (Ballard G et al., 1998). These include formal project management structure, engaged project leadership, clarity in goals, objective and expected outcomes, formality in responsibilities and roles, risk management, project communication, teamwork amongst project staff, delivery capabilities and performance management baseline (Chimhanzi J et al., 2005). According to Zulu, these practices have been applied by firms in all sectors which manage projects or which have project like management processes (Creswell JD et al., 2017).
Project management practices have largely been applied by firms to improve their performance, sustainability and competitive advantage (Easterby-Smith M et al., 2019). This study assessed how project management practices can influence competitive advantage (Eshima Y et al., 2017). A firm is considered to enjoy competitive advantage when it designs and executes a value adding strategy which is different from what other potential and current competitors have (Goldratt EM et al., 1984). Further, the competitive advantage becomes sustainable when rival firms are unable to replicate the benefits, strategies or activities of the firm (Hili P et al., 2017). Great success can be attained by the firm if it focusses on aligning human, internal and marketing capabilities (Hosseini AS et al., 2018). This alignment is achieved by collaboration, coordination and integration of the various departments in the organization including marketing, human resource and operations departments (Hunitie M, 2018).
The relationship between project management practices and competitive advantage have been a subject of theoretical and empirical research in various contexts (Ikeziri LM et al., 2019). Ridwan and Bakri observe that a firm’s competitive advantage and application of project management practices have a positive relationship (Johnston RB et al., 1996). Naeem et al., indicated that possessing a strategic resource that is rare, non-substitutable, imperfectly mobile and valuable is not a guarantee that it will generate competitive advantage (Kasasbeh EA et al., 2017). Andersen supported this view by indicating that adopting optimum management capabilities and practices does not always result into competitive advantage (Kinyua E et al., 2015). However, Eshima and Anderson also observed that an organization cannot attain and sustain competitive advantage without having optimum management practices. When a firm possess a strategic resource, this does not automatically mean that it uses that resource efficiently (Minbaeva DB, 2018). As a result, according to Othman et al., for a strategic resource to contribute to competitive advantage, procedures, activities, and routines must be in place to efficiently use and coordinate its use. These become the link between strategic capabilities and competitive advantage. This study hypothesizes that project management practices can enable a firm to use its resources to gain competitive advantage (Mithamo MK et al., 2015).
This chapter provides a review of the available literature on practices of project management and competitive advantage in convenience stores in Mombasa county (Naeem S et al., 2018). This includes empirical literature on competitive advantage, project leadership, project communication, project risk management and teamwork amongst project staff (Naor M et al., 2013). Besides, the chapter presents the theoretical framework which provides three theories (Competing values framework model, Lasswell theory and Robson risk management theory) that guide the study. Moreover, the conceptual framework, knowledge gaps and summary of the chapter are presented in this chapter (Daniel CO, 2019).
The concept of competitive advantage
The dependent variable in this study is competitive advantage. This is the capacity of a firm to sustainably outperform its competitors, therefore allowing the company achieve superior profitability. Various studies have been conducted on competitive advantage. A study in Iran by Hosseini et al., assessed the factors that affected competitive advantage and also assessed how competitive advantage in return affects new product development. The authors indicated that competitive advantage is attained by an organization when it has profitability that is generally higher than the average of its industry for a long time. This is attainable when a firm has sustainable efficiency, quality, innovation and accountability. This study determined that factors that influence competitive advantage are effective leadership, innovation, branding, cost structure, product quality and customer service.
In Indonesia, Nurisra et al., assessed the factors that determined competitive advantage of contractor companies. The authors had noted that it is important for contractor companies to have competitive advantage to enable them to compete and thrive in the industry. The target population of the study was medium-class contractors in Banda Aceh. The study used questionnaire to collect data from 31 middle-class contractors. The findings determined that relationships between the company and stakeholders, relationship with the government, risk management, project communication and project scheduling and resource allocation were the key factors that determine competitive advantage.
Competitive advantage is an important organizational construct that enables the firm to thrive and renew itself to fit to its environment. Kasasbeh et al., assessed the factors that contribute towards competitive advantage in the banking sector. The study applied six measures of competitive advantage which were service quality, efficiency, innovation, organizational agility and reputation. The findings from the study were that management efficacy, marketing innovation, corporate social responsibility, quality of service and creativity were the key factors that influenced competitive advantage in the banking sector.
A study by Wambugu assessed the factors that influenced competitive advantage amongst the forms in the micro finance industry of Kenya. This study was conducted through a survey and the target population was microfinance institutions in Kenya. The findings of the study indicated that leadership, employee management, risk management, resource integration and employee development were the most critical aspects that influenced competitive advantage amongst the firms in the microfinance industry. Measures of competitive advantage applied in the study included employee growth, sales growth, sustainably high profitability and flexibility.

Research design
A research design is the overall strategy used in a study to combine the many components of the investigation in a logical and cohesive manner to guarantee that the research topic is properly addressed. A descriptive survey research approach was used in this study. This is a design that tries to methodically and properly explain a phenomenon, situation, or population by addressing the questions "how," "when," "where," and "what." This strategy was used for this study because it allowed the investigation to answer the 'what' research questions in the study. The design also assisted the study to assess the influence of project leadership, project communication, project risk management and teamwork amongst project staff on the competitive advantage of Naivas supermarkets in Mombasa county, Kenya.
Target population
Target population in a research is the entire set of individuals, organizations, elements or units for which the study findings are intended to generalize. In this study, the target population was the 112 employees in four branches of Naivas supermarkets in Mwembe Tayari, Bamburi, Nyali and Likoni. The target population is as presented in Table 2.
| Category | Number | % |
| Senior employees | 4 | 3 |
| Supervisors | 23 | 21 |
| Non-management staff | 85 | 76 |
| Total | 112 | 100 |
Table 2. Target population.
Sample size and sampling procedures
This section provides the procedures that were applied in determining the sample size and selecting the units from the target population that will participate in the study.
Sample size
The number of units from the target population who engage in the study is referred to as the sample size. This study's sample size was determined using the calculation procedure by Yamane which is provided hereunder.

In the formula, 'n' is the sample size that participated in the study, 'N' is the size of the target population while 'e' is the selected significance level which in this study was 5%. Applying the formula, the computed sample size is as indicated below.

The total population of 112 employees in four branches of Naivas supermarkets in Mombasa county, Kenya was applied in the formula. Using the formula, 88 was the sample size.
Sampling procedure
The strategy or process of selecting a sample from the target population to participate in the research is referred to as the sampling procedure. To guarantee that the sample chosen is representative of the target group, the sampling process should be appropriate for the characteristics of the target population. Because the study's target population was split between Mwembe Tayari, Bamburi, Nyali and Likoni, which are the four branches of Naivas supermarkets in Mombasa county, stratified random sampling was used. Population was hence selected proportionately. The population is split into groups in this form of random sampling, and the randomly selected sample is selected according to the distribution of the different groups in the target population.
Operationalization of the variables
This section discusses variable measurement and operationalization. The process of converting variables into quantifiable indicators is known as operationalization. Furthermore, the framework in Table 3 demonstrates how all of the variables were assessed as well as the appropriate degrees of measurement (Table 3).

Data presentations, analysis and interpretations
This chapter contains data presentations, analysis of study findings and interpretations of study outcomes and the results. The chapter begins with the return rate and then moves on to the outcomes regarding demographic characteristics of the study participants. Besides, the chapter presents a discussion of the diagnostics tests conducted, the descriptive statistics in relations to the study objectives and the linear regression results for each of the study objectives. The testing of the hypothesis of the study results in relation to the theoretical and empirical literature is also provided in this chapter.
Questionnaire return rate
The study targeted 88 employees from four branches of Naivas supermarkets in Mombasa county, Kenya and received responses from 72 research participants. This related to an 81.8% success rate which was considered adequate. Saunders et al., posits that any response rate above 60% is considered adequate in descriptive surveys in the social sciences, management and business research. Following this authoritative assertion, the response rate in the study which was above the minimum stipulated was considered adequate.
Demographic characteristics of the respondents
The study explored various demographic characteristics of the respondents including gender, the highest level of education attained, the age and the number of years that the respondents had worked for Naivas supermarket. Descriptive statistics were used to summarize these responses and the findings are presented hereunder.

CONTRIBUTIONS TO THE BODY OF KNOWLEDGE
This study makes significant contribution to knowledge as it provides empirical evidence of the influence of four project management practices on competitive advantage of a firm in the retail sector. This is because most of the available empirical literature on project management practices is mostly on construction companies that mostly deal with projects. This study therefore provides evidence that firms that are not project oriented can also apply project management practices to enhance their competitiveness in the fast-paced environment. Specifically, the study documents how project leadership, project communication, project risk management and teamwork amongst project staff are essential in the retail sector for attaining and sustaining competitive advantage.
