Organizational Impact	Value	Metric	Time Frame

Operational	Eliminate process of updating food database	No food database update process which will done by restaurants and supermarket themselves	6 months ?
Social	Increase awareness of healthy life style	Increase No. of customer by 20%	24 months ?

The original existing nutrition systems of the company provide customer the general functions which could also be found in other competitors’ products. As our proposed new features added nutrition system launches, the outstanding specialty would attract new customers to increase market share from 20% to 40% based on original pie, which would be achieved within 2 years. And, as new type of users involved in our proposed system, target market will penetrate into restaurants and supermarkets.

By improving the data entry efficiency of reducing the input procedure from 5 to 3, and giving more nutrition tips and reminders, our proposed system would definitely become more and more attractive. Moreover, we change our charging type from software renting payment one time forever to monthly payment. The overall revenue would increase by 15% in 2 years’ time.

As restaurants and supermarkets taking part in our proposed system, they’ll update their food database regularly all by themselves in order to attract customers for competition, we eliminate the database updating process, which would decrease the maintaining cost and data updating errors that would increase the efficiency of system’s operation.

From social perspective, the more customers using our system, the more aware of healthy life style in the society. This is our prospect in long-run.

Dear all,

I have post the discussion result of Project Mgmt case, the file name is "Case Discussion.rar" in the "File part."

Thanks,

Objective

?

In this work, a nutrition system with Internet-enabled PDAs and web server is proposed, which can be used to keep track of user’s diet and workout history, generate warnings of unsuitable food based on users’ body information, and create periodic health reports.

?

The existing systems have the following main problems. First of all, somebody does not understand how to use the existing systems. To illustrate, the measurement of blood pressure is hard to certain users who do not how to know measure blood pressure. And the amount of workload is hard to measure. Second, the exiting systems do not motivate the users to enter data. Perhaps, the users forget, even detest, entering the data in certain days. Thus, the system cannot work out properly the result based on the incomplete data. Third, the existing systems do not provide notification for user under some situation. For example, when a diabetic orders a dish with high sugar, the existing systems do not give the user a warning.

?

The proposed system has four types of new services. Patient care service using notice and warning message to helps patients take care of their diseases. Food comparison service compare nutrition facts of different food that users want to choose from, and then recommend users of the more nutrient one. Tips service shows nutrition tips every time the system is activated. Online service includes Food recommendation, Eating pattern recommendation and Health report.

Features

Compared with other existing nutrition softwares on the market, our proposed system has more novel and creative features, that satisfy different users’ various requirements, besides the basic functions ， which has been mentioned in the background part.

l???????? Patient care service:

This function uses alter, notice, and warning messages to take care of patients.

n???????? The proposed system can remind patients of taking pills, or doing any recovery exercise on time. Reminding message will automatically pop up when it is the time.

n???????? For patients with certain diseases, such as diabetes, or high blood pressure, the proposed system would remind them of what kind of food they can eat, and what cannot.

l???????? Food comparison service:

n???????? The proposed system can do food comparison. It would compare nutrition facts of different food that users want to choose from, and then recommend users of the more nutrient one.

l???????? Tips service:

n???????? It would show nutrition tips frequently to endorse users, sticking to their goals.

l???????? Online service:

Besides the software installed on the PDA, a server would be set up to provide various services for the PDA software.

n???????? Food recommendation: The server can analyze users’ inputs from the PDA system, and then tell the most popular food of each restaurant.

n???????? Eating pattern recommendation: the server can analyze users’ eating patterns, and then recommend the healthier one to other users or the more successful weight loss menus to different users.

n???????? Health report: the proposed system would have monthly or weekly health reports for the users. Users can also check their health status in the past, by sending request. These reports would be in graphics patterns.
