The correct answer is: A bill of material is prepared in case of a standard job.
A bill of materials (BOM) is a list of the components that make up a product, along with the quantity of each component required. It is used to plan and control production, and to ensure that the correct components are available when needed.
A standard job is a job that is performed repeatedly, with the same steps and procedures each time. This type of job is well-suited for use with a BOM, as the components required can be easily identified and tracked.
A non-standardized job is a job that is performed less frequently, or with different steps and procedures each time. This type of job is not well-suited for use with a BOM, as the components required may vary from one job to the next.
In conclusion, a bill of material is prepared in case of a standard job, as this type of job is well-suited for use with a BOM.
