解説
問 22
Incorrectア
“The division of roles of the ordering (client) company in carrying out the development” is about who inside the client company itself takes charge of which work, and it is a matter the client should decide on its own. It is not information collected from vendor companies. In addition, making concrete the division of roles that accompanies how the development proceeds belongs to the stage of concluding procurement or development contracts, and it is not something to settle at the concept formulation stage, which only draws the broad picture. The question asks about “information collected from vendor companies”, so on that point alone this choice is wrong.
Incorrectイ
“The cost estimate for developing the planned system” is something received together with a vendor proposal after going through the systemization plan and the requirements definition and presenting the functions and scale to be realized as a Request for Proposal (RFP). At the concept formulation stage the target scope and the functions are still undetermined, so even if a vendor produced a figure, it would only be a number with no grounds and could not serve as material for a decision. Because the time to collect it is a later process, it is not the most appropriate information at the time of formulating the concept.
- ウ
正解 The correct answer is ウ. Formulating a systemization concept is the process that sits at the entrance of what the Common Frame calls the planning process. Starting from the management strategy and business issues, it is the stage where the broad direction of “what kind of system will achieve what” is drawn. At this point neither concrete requirements nor specifications have been decided. The information that the ordering company can hardly obtain by itself at this stage is exactly which technologies have now become usable in the target field, that is, information technology trends. Vendor companies have knowledge of many implementation cases and of the latest products, so the client asks them to provide technology trends through means such as a Request for Information (RFI), learns the range of feasible approaches, and then builds the concept on that basis. Only once the technology trends are known do the premises of the concept become firm: what can be achieved in that field, and how much effect can be expected. Therefore, the most appropriate information to collect from vendors at the time of formulating the concept is ウ, “Information technology trends in the field to be systematized”.
Incorrectエ
“The technical qualifications held by the vendor company's engineers” is information checked at the procurement and vendor selection stage, where several vendors are compared in order to judge which one to place the order with, so as to evaluate their implementation structure and technical strength. At the concept formulation stage the choice of a supplier is not yet on the table, nor is this information that helps to firm up the content of the concept (what is to be achieved). Because it is off the mark in both purpose and timing, it is wrong.
ここがポイント
- The planning process proceeds in the order “formulating the systemization concept” → “drawing up the systemization plan”. In formulating the concept, besides confirming management needs and issues and analyzing the business environment and operations, you investigate the applicable technologies (grasping information technology trends) and form an outlook on the means of realization.
- Approaches to vendors are used differently by stage. The concept stage is when a Request for Information (RFI) is used to gather information broadly, such as technology trends and feasibility; the procurement stage, after the requirements are settled, is when a Request for Proposal (RFP) is used to ask for a concrete proposal, estimate, and project structure. Remember them as this pairing.
