A technical specification details the standards that a product or service must meet. Drawings (often called engineering drawings or technical drawings) are complementary to technical specifications

In this question, you should understand the concept of cash flow and formula of cash flow. Cash flow calculates the physical money moving in and out a company's bank balance. The cash flow from sale activity is:
cash flow from sale = account receivable at beginning of the year + revenue - account receivable at the end of the year = $450,000 + $5,000,000 - $525,000 = $4,925,000
75% of direct costs was bought by credit, therefore, the company spent 25% on direct cost: -$2,500,000*25/100 = -$625,000
25% of indirect costs was bought on credit. Cash flow out on indirect costs is: -$3,000,000*75/100 = -$2,250,000 Company spent $1,500,000 on new assets funded by a loan of $1,000,000. Cash flow out from this activity is -$500,000 Company received $150,000 from selling old assets Dividends have not been paid for another 2 months, thus, they are not accounted as cash flow out.
The bank balance at the end of the year is: $175,000 + $4,925,000 - $625,000 - $2,250,000 - $500,000 + $150,000 = $1,875,000 LO 1, AC 1.4

Direct costs are directly associated with the production of a good or service. In this question, 'An employee is hired to work on a project, either exclusively or for an assigned number of hours' and 'Raw materials' are directly related to producing the product.
Indirect costs are the general costs of the organisation - these costs cannot easily be attributed to specific products or services (also known as overheads). 'The materials and supplies needed for the company's day-to-day operations' or 'Clerical assistants who maintain the office' or 'Advertising and marketing communication' is example of indirect cost.
Reference:
LO 1, AC 1.2

Writing a specification and then procuring and using the product or service has a number of stages. The further on in the process you are, the less potential there is for cost reductions. Therefore, opportunities for cost reduction will be greatest in the two first stages: planning stage and pre-design stage.
