Zoom Vacuum, a family-owned manufacturer of high-end vacuums, has grown exponentially over the last few years. However, the comp

Sati [7]

Answer:

The best advice for Zoom Vacuum is to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users engage with the TPS and generate, retrieve and update the data. it would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products.

Although, TPS alone would not be sufficient enough. so Management Information System(MIS) would be needed, that can get the data from the TPS and process it to get vital information.

This MIS will bring about information regarding the sales and inventory data about the current and well as previous years.

With the combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.

Explanation:

Solution

When we look at the description of the Zoom Vacuum manufacturing company closely, we see that the business is currently a small scale business which is trying to become a small to mid scale business. This claim is supported by the fact that there is only one manufacturing plant and three warehouses. And here, we also need to have the knowledge of the fact that small business major aim is to keep the cost low and satisfy the customers by making good products. So we need to suggest what information system is best suited for small scale business enterprises.

The best recommendation would be to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users interact with the TPS and generate, retrieve and modify the data. This TPS would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products . Also TPS can help in communicating with other vendors.

But TPS along would not be sufficient. Also Management Information System(MIS) would be required that can get the data from the TPS and process it to get vital information. This MIS will help in generating information regarding the sales and inventory data about the current and well as previous years. Also MIS can create many types of graphical reports which help in tactical planning of the enterprise.

So a combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.

A digital system has been developed to measure temperatures in the range -10˚C to 100˚C. If the accuracy of the system is such t

8090 [49]

If you have 10 bits available then you can interpret any number in range $[0,2^{10}-1]=[0,1023]$ .

The system therefore could represent the actual temperature of 39°C.

Hope this helps.

Can you withdraw from courses in top hat?

ad-work [718]

Answer:

Yes, but this must be done before the withdraw deadline

Explanation:

TopHat is an online learning platform. Students register for courses and if they decide not to continue with a course for reasons best known to them, they are allowed a time period usually one to two weeks to drop the courses. They are then reimbursed the fee for that particular course.

But if that time period elapses and they drop the course, that is considered a withdrawal that is not accepted and which no provisions for reimbursements are made.
