Abstract:
Construction industry in Sudan is considered as the largest industrial sector that has a direct effect on the state economy. The productivity of this sector has declined in Sudan and all over the world since 1960.
This study is trying to measure the relationship between the productivity of construction industry in the Sudan and motivation. A mathematical model is adopted to measure this relationship. The model is:
P = P0 + C1X1 + C2X2 + C3X3 …… (6.13)
Where: P, P0, X1, X2, and X3 represent Productivity, Productivity without motivation, Physical motivation, Moral motivation, and Job satisfaction respectively. C1, C2, and C3 are the constants of physical motivation, moral motivation and job satisfaction respectively.
The overall objective of this thesis is to enhance the productivity of construction industry in Sudan.
The questionnaire was distributed to numbers of respondents. A sample of 77 companies drawn randomly from stratified samples, to represent the population of the industry’s companies and work names. Three hundred and fifty persons involved in those companies responded to the questionnaire. Statistical package for social science (SPSS) used to analyze the collected data. The answer to the questionnaire’s questions revealed that the motivation increased the productivity by 5.2 % and the relationship between the productivity and motivation in the respondent companies can be represented mathematically as:
P = 0.408 – 0.130X1 + 0.304X2 - 0.209X3
This result means Sudanese companies only apply moral motivation to motivate their employees. Moreover, there is no enough physical motivation system in these companies, and the majority of workers are not satisfied with their jobs at these companies.
