- Design a study to identify what might be the probable ultimate cause/s of the decline in sales. For looking at the different causes, consider the box and arrow diagram given. Note the following things about the box and arrow diagram: If the arrow’s head is towards a box, that means the variable in the box (where the arrow’s head is) affects the variable in the box from where the arrow originated. E.g “Revenue/Sales” is affected by the “Number of shoppers/customers”. The boxes in grey are the variables you as a firm/owner can directly expect to affect which can further affect other variables in the model. E.g. You can incorporate training programs to improve “customer service” perceptions and, ultimately “Sales”. There is a hierarchy of the variables such that we have started from the broadest ones in thetop and then went to the finer one.

- In making squash soup, what are the tests to quantify certain parameters as indicators of quality?arrow_forwardIn a car manufacturing company, an automated painting process has been introduced, and the quality assurance team suspects there might be issues that require investigation. The team decides to conduct a root cause analysis to identify potential problems. Through the root cause analysis and further investigation, it appears that the drying time of the paint in minutes is affecting the overall quality of the finish. The aspect they need to examine is the variation in drying time across different colours of paint. Considering the ongoing concerns in the painting process, the team chooses to collect a sample of six drying time measurements every 20 minutes from various colours of paint. The recorded drying time values for a day's production are presented in Table 1. A total of 10 sets of measurements, each consisting of six drying time values in minutes, have been collected. Each time a set of measurements is taken, the individual drying time values are recorded. Table 1: Drying Time…arrow_forwardsniparrow_forward

Appraisal costarrow_forwardi) The concept of quality is considered to have evolved through stages. However, quality is used to describe a prestigious product. It is one that fits the intended customer’s requirements. Impliedly, the product should possess attributes that enables it meet the customer’s requirement or specification. Now, in identifiably distinctive manner, differentiate quality control from the others or quality assurance. ii) Briefly define hazard, when uncertainty is defined as being a situation in which the determination of risk factors is not possible. It is difficult therefore to calculate the effect of uncertainty upon the tender, and a discussion of uncertainty is out of place here. A builder will see risks in two distinct categories: (a). those that can be insured against and,( b). those that cannot be insured against.arrow_forwardIn response to intensive foreign competition, the management of Florex Company has attempted over the past year to improve the quality of its products.
