解説
問 4
- ア
正解 The correct answer is ア. An RFP (Request For Proposal) is a document in which the ordering party puts together the requirements for the system it wants, the preconditions, and the content it wants vendors to propose, and presents it to the vendors. It is a basic step of procurement to decide in advance, at the stage the RFP is issued, the evaluation criteria (the evaluation items and their weights) that state what will be evaluated and how the choice will be made. Once all the proposals are in, the proposals of the different companies are scored and compared with the same yardstick according to those criteria set beforehand, and the vendor with the highest total score is selected. This keeps the conclusion from being swayed by the personal views of the person in charge or by reasons invented after the fact, and it makes it possible to explain the selection result objectively both inside and outside the company (securing fairness, transparency, and accountability). If the criteria were decided after seeing the proposals, criteria favorable to a particular vendor could be created later, so setting them in advance is the important point.
Incorrectイ
Cost is certainly one important evaluation item, but deciding on cost alone is inappropriate. Without looking at the proposal contents, you cannot tell whether the requirements are met, or whether the quality, the delivery time, the maintenance and support setup, and the vendor's track record and development structure are sufficient. Choosing only by cheapness means taking on risks such as unmet requirements, poor quality, extra costs, and project failure, so the total cost ends up higher in the end.
Incorrectウ
SWOT analysis is a technique that organizes mainly the internal and external environment a company is in, from the four viewpoints of Strength, Weakness, Opportunity, and Threat, in order to build a management strategy. It is a tool for planning one's own strategy, not a selection technique for comparing the submitted proposals against each other to decide which vendor to order from.
Incorrectエ
The function point method estimates the size of software from the number and complexity of the functions as seen by the user, such as input/output screens and the number of files, and it is used to estimate development effort and cost. What it measures is only the size of the functions, not which proposal has the better developed functions, so it cannot serve as a selection criterion for evaluating a vendor's whole proposal.
ここがポイント
- An RFP (Request For Proposal) is the document with which the ordering party asks vendors for proposals. In vendor selection, the evaluation items and their weights (the evaluation criteria) are fixed in advance at the stage the RFP is presented, and once the proposals are received each company is compared and scored side by side against those criteria. This is what secures fairness, objectivity, and accountability.
- Telling the confusable techniques apart: SWOT analysis is a technique for organizing a company's own internal and external environment in order to build a management strategy, and the function point method is a technique for estimating the size of software (effort and cost). Neither of them is a technique for vendor selection itself.
