The company headquarter is located in United Kingdom with branches in over 40 countries. The company has a long term relationship with its customers and always committed to providing excellence services to customers. A valuable experience employee affords the Company a unique and valuable combination on global perspective and competition. AMEC Company has the ability and experience of delivering complex and large projects for its customers within the budget. Mission Delivery excellence, integrated and people oriented business, producing high-value solutions for our customer Company Vision To be a world class oil and gas producing Company meeting the customer needs at affordable price. AMEC Company is the leading asset provider and support provider in the industry. With a vast experience in providing consulting services. Services which the company provides include Engineering Consulting Project management Construction Decommissioning Environmental services Supply chain management. The sector at which the company is operating includes; Oil and gas Mining Nuclear Unconventional oil and gas Power Renewables/Bioprocess Power Water Transmission and distribution Has it expands rapidly; the company human resource department has experienced challenges concerning employee recruitment, employee promotion, employee monitoring and employee remuneration. There is need for the company human resource manager to monitor the movement and development of his employee. To solve this problem, the company will develop a human resource system which is capable of Adding a new employee Deleting employee name Store employee details Processing of leaves automated online with tracking system. Assign employee under manager. Give mission or project or assignment to employees. Time attendance Promotion systems This kind of system will be beneficial since everything will be monitored online. Project Lifecycle Project life cycles are stages through which a project passes through before it is put into operation. There are four major stages which the human resource management system will pass through. They include; Starting up the project this includes concept design, initiation, selection, planning, business case and scheduling (Booch, 2004 P42). Preparation and organization – this involve definition, development, feasibility confirmation prototype design and quantification. Execution- which involve work implementation, production, realization and design construction and testing (Booch, 2004 P42) Closing the project which include handing it over and some post-completion evaluation Fig. 1.1 Project Life Cycle Model (PMIa, P16) The phases are simple and easy to understand by both classes of people. Methods of Data collection Two methods of data collection and fact findings were used. These methods were used to uncover all the requirements used in building the human resource system. The process used includes; Joint Application Development (JAD) Document analysis These processes were chosen due to their flexibility and the nature of system to be developed. The joint Application Development enabled the developer to directly here and discuss the problem with the client hence the system developed will be more user friendly and more customized (Carroll, 2005 Pg 89). The use of document analysis was chosen because the system developer can have deeper understanding of the number of employees and the current employee management style Joint Application Development (JAD): Both the human resource manager, finance officer and the company director were some of the people involve with the analyst and system developer to discuss the problem and the desired kind of system to be developed. We went to a closed room and discussed the problem in a round table exploring different types of possible systems with their advantages and disadvantages. The outcome was recorded in a tape and hand written Document Analysis: This helped in providing information “as-is” system and the developer reviewed the user documents and concern. Past HR. records were subjected to scrutiny in order to diagnose the problem fully (Carroll, 2005 Pg 92).
