In preparing a reason or justification for a development proposal, Ahmad realized that the proposal should describe the project clearly, provide the justification to proceed and estimate the project's financial impact. Ahmad has gathered necessary facts from various sources. He was particularly puzzled by the little responses from the company's finance manager from the questionnaire that he had distributed earlier. Although he did not know about the specific information needs of his finance manager, he continued the analysis process by conducting various aspects of feasibility studies. Required: a) Justify ONE (1) fact-finding method which you find most suitable in Ahmad's case. (5 Marks) b) Discuss the importance of having a comprehensive development proposal.
