The Effect of Time and Cost Overrun on the Quality Performance of Construction Projects in Lagos State.
(Bells University of Technology, 2024-03-07) NWENEARIZI, John; Prof. F. A. Oyawale
The uncertainties and complexities of a construction project often cause differences in what has been planned and its execution in the field, resulting in time and cos overruns. The successful implementation of a construction project is target and expectation of the project owner and contractor, who have an effective time with a budget that is according to plan. This research work is to investigate the factors causing time and cost overruns in construction projects to provide solutions to the problems created by the effect of time and cost overrun on the quality performance construction projects in Lagos state. Research works on his topic have been done by many researchers, some of whose works have been reviewed in my proceeding sections. However, the extent to which these phenomena has affected quality performance of construction projects in Lagos, Nigeria, have not been adequately explored. More than 15 literatures which have covered similar topics were reviewed. Primary data was collected through questionnaires survey to the relevant stakeholders in the industry. Two sets of questionnaires were administered to professionals and stakeholders on project bases, and it covered 98 and 89 construction projects in Lagos state respectively. The reliability of the data from the questionnaire was tested with Cronbach's' alpha. These data were processed and analyzed using both descriptive and inferential statistics- ANOVA and test of hypothesis. Cronbach's alpha of 0.96 was got which signifies high reliability of the data. This research has identified and ranked top ten factors with high relative importance and severity indices (ranging from 0.74 to 0.60 and 74.29% to 58.57% respectively) that has triggered time and cost overrun in construction projects in Lagos state.

Numerous office -based organization have seen a sudden transition to remote employment as a result of the covid- 19 epidemic. The objective of this research is to investigate the impact of remote work on the performance and employee engagement of office workers from three different generation organizations. This research examined the ways in which workers manage their work routines and home activities in order to achieve maximum performance in their professional assignment. In, addition, the Nigeria energy infrastructure has been afflicted by several challenges, including low gas pressure, grid restrictions, and system collapse. Consequently, obtaining precise statistics on this matter is not possible. The research examined the impact of remote work participation on workers' performance. Data was obtained from 286 respondents who are workers of three chosen energy organization in Lagos and Kogi, Nigeria. The data was analyzed using the Pearson Chi Square statistical approach. The findings of this research indicates that remote work is strongly correlated with workers' problem-solving skills, job quality, time management abilities, and productivity in the energy businesses examined in Nigeria. Thus, the steps taken to help mitigate employees' performances were identified.
Effect of Quality Assurance Tools on Product Quality in Food and Beverage Industry in Nigeria.

Project risk is a factor in success or failure of any project. The strategic management of the risk within the construction company is the issue addressed in this study. The study identifies the risk factors inherent in Building Construction Projects and impact of risk audit in mitigating the effect of the risk factors on quality performance of building construction project5 in Nigeria. Data were collected using questionnaire through stratified and simple random sampling techniques which are rated on 5 Likert scales. Student T-test was used to determine the difference in the identified risks, linear regression analysis for influence of risk management strategies on project success and associated risks on the project success as 215 (69.13%) participants were in Favour of it, 142 (45.66%) respondents agreed on the adverse effect of weather system risk affecting projects success while 176 (59.59%) of the respondents were in Favour of geological system risk. Further investigation claimed that 240 (77.17%) respondents concurred on social risks, 191 (61.41%) for political risk, 269 (86.50%) for financial risks, 96 (30.87%) for manageri8al risk, 174 (55.95%) for health risks and 182 (58.52%) concurred with technical risk. T-test result of 10.975 shows that there is significant difference in potential risk ientifie4f in the study area. It was discovered that 0.7%, 1.5%, 10%, 6.7% and 3.3% of the project success was affected by operational risk, geological system, social, political and financial risks and all are insignificant. More importantly, 219 (70.42%) of respondent accorded identification of risks as the most critical part of the strategy while risk prevention and diversification claimed 191 (61.41%) Reponses 181 (61.41&) for risk transfer and outsourcing, 137 (44.05%) for risk acceptability, 155 (49.84%) for monitoring and control and 172 (55.31%) for employee training and awareness on risks.
Effects of Attrition on Project Closure of Software Development Companies in Lagos, Nigeria.
(Bells University of Technology, 2024-03-08) ADAJERO, Tega Sylvester; Prof. O. G. Akanbi
In the ever -revolving sphere of software development, managing projects to successful closure without missing deadlines and delivering the proposed results remains a critical challenge for most software development organizations. Attrition has been identified as one of the most significant factors affecting projects outcomes, specifically software development projects. This study investigated the existence of attrition, the effects of the attrition on projects closure of software development companies in Lagos Nigeria and recommended the adoption and practice of innovative strategies to efficiently manage attrition. The study utilized simple Random Sampling technique to select 100 respondents from the population size of 315. To gather required data needed for the research, the4 study distributed 100 copies of a well-structured questionnaire to our targeted respondents who were mainly employees od employers of software development firms in Lagos. Of the 100 copies of the questionnaire that were administered in two batches, 82 were retrieved, but preliminary checks revealed that 76 were properly answered so were deemed fit for use while the remaining 6 were not answered properly, so were not considered during the analysis. The data gathered was analyzed using Pearson's product moment correlation coefficient (PPMCC). Findings showed that attrition poses devastating challenges to software development projects. These challenges includes delay in project timelines, increased project cost, loss of domain expertise and disruption in teams' cohesion. The outcome of the research also revealed the top three major factors causing attrition as lack of adequate compensation or benefits, lack of opportunities. The study concluded by recommending the adoption and practices of innovative strategies for efficiently managing attrition despite the challenges it poses to software development companies and such projects to ensure improved project performance and successful completion.
