Production function and its cycle

[yogin]

The production cycle starts and ends with the customer.
Production is always as per the needs, requirements and expectations of customers.
Companies conduct marketing research activities and find out the product, which consumers need. Thereafter, the market demand is estimated through sales forecasting.
Production planning is necessary and useful for the conduct of production activity in an order manner.
The whole production activity moves continuously till the production activity is completed. Here, one production cycle comes to an end. The goods produced are marketed thereafter.
In due course of time, once again the same exercise is repeated. The new production cycle starts with the study of consumer expectations, possible demand and so on. This suggest/justifies the statement that production cycle starts and ends with the customer.
The sales department studies the reactions of consumers to the products available in the market and the extent to which the consumers are satisfied with them. The marketing research will be also conducted in order to find out the possible reaction and support of consumers to the new product which the company desires to introduce and which can act as the base of the whole production cycle to be introduced.
The conclusions drawn from the research work will be used for decision-making in the subsequent stages of production cycle. The details collected (data collected) by the sales department and the market research department will be used as the base by the sales department in order to find out the acceptability of the product by the customers and the extent of such acceptability. This information will be submitted to the top-level management for decision on the production to be conducted in the proposed production cycle. The sales forecast prepared will be used for preparing production budget by the finance department
