  2. Listening to what the client wants, combining equipment and software into a system, and delivering it
  3. Selling a service it has planned itself to a large, unspecified body of users
  4. Designing semiconductors and outsourcing their manufacture to other companies
AnswerB. Listening to what the client wants, combining equipment and software into a system, and delivering it

System integration means hearing the requirements, designing to them, combining equipment and software into something that runs, and delivering it. The specification is set by the client who placed the order, and that is the big difference from an in-house service.

  1. A joint venture of several companies
  2. Vertical integration, keeping the processes in-house
  3. Mutual access, with facilities lent to one another
  4. A layered subcontracting structure
AnswerD. A layered subcontracting structure

The party contracting directly with the client is the prime contractor, the party taking work from it is the first-tier subcontractor, and the next one out is the second-tier subcontractor. The deeper the layers, the further the client is from the people actually doing the work. Where a company sits can be read from its major customers and its case studies.

Q13 | Contracts for work

Which correctly states what a contract for work (請負) is under the Civil Code (民法)?

  1. A contract to lend a thing and receive rent for it
  2. A contract entrusting the handling of affairs, under which remuneration is paid for the affairs handled whether or not the work is completed

  4. A contract to dispatch workers to another company and have them work under that company's direction
AnswerC. A contract under which one party promises to complete work and the other promises to pay remuneration for the result of that work

Article 632 of the Civil Code provides that a contract for work becomes effective when one party promises to complete certain work and the counterparty promises to pay remuneration for the result of that work. The distinguishing feature is the duty to complete.

  4. It is a special provision on the sale of goods
AnswerC. It applies the provisions on mandate mutatis mutandis to the entrustment of affairs that are not juridical acts

Article 656 of the Civil Code provides that the provisions of that section apply mutatis mutandis to the entrustment of affairs that are not juridical acts. In system development, contracts for work, which promise completion, and quasi-mandates, which take on the work itself, are used for different situations.

Q15 | Dispatch and contracting

On distinguishing a worker dispatch business from a business carried out under a contract for work, which is the correct view shown in the notification?

  1. If the contract is headed as a contract for services, it is treated as a contract for work whatever the actual working arrangement is
  2. If the work is done outside the client's building, it is necessarily a contract for work
  3. It is a contract for work if the contractor directly uses the labour of the workers it employs itself and handles the work independently of the counterparty
  4. If remuneration is paid monthly, it is a contract for work
AnswerC. It is a contract for work if the contractor directly uses the labour of the workers it employs itself and handles the work independently of the counterparty

Ministry of Labour Notification No. 37 of 1986 (昭和61年労働省告示第37号) makes it a requirement of a contract for work that the contractor itself decides how the work is carried out, the working hours and the assignment of staff, and handles the work independently of the counterparty to the contract. What counts is the reality, not the title on the contract.

Q16 | Contract work and own service

Which correctly states the difference between contract development and developing one's own service?

  1. In developing one's own service no design stage is set at all, and building may start from requirements definition alone
  2. Contract development builds to a specification the client has set, while an in-house service is built to a specification the company sets itself
  3. Contract development is always carried out as worker dispatch, and contracts for work or quasi-mandates are never used
  4. In contract development no invoice is issued to the client
AnswerB. Contract development builds to a specification the client has set, while an in-house service is built to a specification the company sets itself

The difference lies in who sets the specification and who pays. In contract work the client sets the specification and pays the price; with an in-house service the company sets the specification and receives usage fees from a large, unspecified body of users or from contracted companies. That is separate from the form of the contract.

Q17 | Person-months

What does the unit called the person-month, used in estimating contract development, express?

  1. The volume of work, the number of people multiplied by the number of months
  2. The usage fee for using a service on a monthly basis
  3. The number of users who used the service in a month
  4. The monthly salary paid per engineer
AnswerA. The volume of work, the number of people multiplied by the number of months

The person-month is a unit of work volume, people multiplied by months, and an estimate is often produced by multiplying it by a unit price. This leads to a difference: contract work books sales for the work done, while an in-house service accumulates usage fees over time.
