Authors: *Ogbeide O.O, Ozigagun A, Agbondinmwin U
Productivity measures how efficiently production inputs, such as labour, capital and material are used in an economy to produce a given level of output. Productivity growth constitutes an important element for modeling the productive capacity of the economy. The objective of this study is to analyze the impact of productivity, while using the inventory of the construction sector of Julius Berger Nigeria Plc as a case study to investigate, measure, plan and control the productivity and performance of the firm. Secondary data were used for this study and was generated through the firm's annual reports and financial statements to assess the productivity of the firm. Results show a low increase in the company productivity. Statistical quality control techniques were used to check the controllability of the system. The control chart of the mean and range chart was employed and the results obtained shows that the construction process was in control. The result of the statistical quality control techniques indicate that the construction process is under control. The investigation revealed that factors in both external and internal work environment as well as the firm's policies are unfavorable to the enhancement of labour productivity.
