Result of PMI

 

I. Net speed problem

 

 

Plus:

• To get a great effort on improving the network speed in our residence local network, not only for the e-mail and msn anymore.

• The students in the school residence have a local area network with great speed inside.

• It is easy for them to transfer files, play games, or share what they have in their computer in the network.

• The students who live in C.I.C residence could have a high-speed internet interface without paying any more fees.

• All of the staff could be please with these changes that local network will work well constantly and never be cut off frequently.

 

Minus:

The student might have to pay for the network improvement to get a much higher internet speed.

There still could have many viruses inside the local network that could damage the new computers which do not have the virus-protection.

The solution seems not very easy, we should consider among the hardware, money and technology on the network and taking a look at the net mode and interface is also necessary.

There are also many the sexual and illegal messages and pictures sharing on the internet which is hard to remove or restrict with.

We may be forbidden to do it by the school staffs.

 

 

Interesting:

It is a strange thing that the school is feed backed about this problem but do not take any effort on it.

It is the time to consider it, not only for the entire of the student, but also for the residence fee that we have paid.

The internet speed is so slow right now that sometimes the students spend 20 minutes for opening one homepage!

The school promised that we could have a great internet solution before we attend in, but seems we are all fooled by its advertisement.

 

 

 

 

II. Cafeteria system.

 

 

Plus:

It could save a lot of time for the student and staff.

Meal plan checking will be easier that ever before.

The students will not have to wait in a long queue in order to get the food anymore!

The solution could also help the school trace out the students who do not pay for the meal plan.

You do not have to worry about tickets caring and losing.

Avoid the mistake of the staff which is made by checking the wrong black so that the students can eat the right meal.

 

 

Minus:

The machine which can check the students¡¯ code of the meal plan is needed.

The high-tech machines are not cheap.

The details should be considered in many ways.

If the students forget their ID card for check in, they could be forbidden to eat, and that much worse than losing the meal ticket.

 

 

Interesting:

It is a nice thing to have the meal plan easily.

You could be pleased that there is not long queues outsider cafeteria anymore.

The solution is good to deal with.

The students will carry their ID card all the time.

 

 

 

 

III. Coin-Operated Locker System:

 

 

Plus:

The students and teachers will have a convenient locker system to put and withdraw their goods at anytime.

They do not have to memory the code of the locker.

It saves much time to open it.

The locker is the same safe as the code-locker.

The usage frequency could be increased a lot.

You do not have to pay any locker deposit and loaded down with trivial details of the application for the locker.

It is so great that you can choose the locker at anywhere which is left empty.

 

 

Minus:

People should have a coin with them when they want to use the locker.

You should keep the key of the locker and do not lose it. If the key is lost, there could be a charge for it by the school and it is also a hard thing to open the locker.

The replacement of the locker system will cost a lot.

It is not easy to change the locker system since the code-lockers are built inside the wall of the building firmly.

 

 

Interesting:

It could be an interesting to use the locker just like the wash-machine.

You do not have to worry that there is not more locker to be applied or no people like to share a locker with you.

Our school could cut down a task about the locker application.

 

 

 

 

 

 

 

 

Summary of Problem I

Problem I: Net speed.

 

 

Detail of Problem:

     The student might have to pay for the network improvement to get a much higher internet speed when we use it to work, and the net speed is so slow that nobody can accept it. In addition, there still could have many viruses inside the local network that could damage the new computer which do not have the virus protection.

 

Target Users:

The student who have computer in their residence, and the student and teachers who use the computer labs in C.I.C.

 

Solution:

We can use the software to solve this problem, and it could save much money. But this could not take much effort on the solution.

We need set more quantity and powerful cables for example, loom cable.

To project the system every week.

To repair the internet line and change the old slower hubs.

 

 

Summery:

     In residence the students always use the internet days and weeks. However, the net speed problem takes many troubles to us. For example: When they want to find much information on internet for studies, they suffered from every time they connect. Since we time is money, saving the time is saving the money in our lives. In fact the internet speed is too slow right now that sometimes the students could spend 20 minutes on opening one pages in their web browsers! The school promise that we could have a great internet solution before we attended in, but seems we all fooled by its advertisement. It is nonsense that we can save money from net speed if don¡¯t need the cable modem.

     Above all, every student thinks the net speed problem is important than the other problems. A great solution will make we think we could be their heroes on their home works and communications.

 

 

 

Summary of problem II

Problem II: Cafeteria system.

 

 

Detail of problem:

There are too many students stay in line at the front of the cafeteria when the lunch comes. We have to spend nearly 1 hour on having lunch, and that makes us feel tired and fuss too. Both Asia and Western food are offered in the same line, and that is very inefficient. For example: The students who stay in the middle want to eat Western food have to wait until the front of students get Asia meal. It is great ideas to save teachers or students¡¯ time during the meal time, and let the staffs in the cafeteria have an easy job.

 

Target Users:

The teachers; students in C.I.C.; and the staff who check the student¡¯s meal plans.

 

Solution:

An interview to the staffs that is in cafeteria for opinion of student and make a record.

Buy a machine, which calculate each time that you eat and rest of money.

Use a code machine to check students¡¯ ID card; then it can save more time, and let the students to have meal as soon as possible.

 

 

Summery:

     We always spend too much time on lunch time. Due to the fact that we should find a short cut that we can save our time. For example, after period 3 and 4, the students must feel very hungry and want to have meal immediately. But when they go to the cafeteria there are many people waiting outside. If school could use a code machine to check students¡¯ ID card or teachers¡¯ staff card, then the students and teachers could have meal as soon as possible, and we will not be afraid of losing the meal plan tickets and being refused to pizza place anymore! As you can see, let everyone eat what they want, and makes the staffs in the cafeteria feel easier by saving their time is possible under this solution. Also, it is helpful by improving the meal plan in our school instead of checking tickets days and days.

     Actually, the meal card looks a bit like the bankcard. You can put money into the deposit, and then just brush the digits off from the machine. The more time you eat, the less money you have inside the card. It is a good idea for students that if they want to eat different values of the food, and also they could eat outside. The convenient way is just out your card in, and then you go and enjoy the lunch.

 

 

Summary of problem III

Problem III£ºLockers usage factor and improvement.

 

 

Detail of problem:

      In Columbia International College, the amount of lockers is not satisfied for the requirements of students. Now many new students are still waiting for renting lockers, but the amount of lockers is not enough. The locker is narrow. Thus, some students who do not often use lockers forget the secret code of lockers easily. Some times the secret code locker is not safe.

  

Target Users:

The all students who are studying in Columbia International College.

 

Solution:

An interview to the students which is about the opinion of lockers and make a record.

Readjust the lockers system and increase the amount of lockers.

Change a better lockers system.

 

 

Summary:

     This problem is an important problem for the new students who are still waiting for renting the lockers, because they have to take many test books to go to school, they say that is so heavy and so tired to bring them. For this type of this problem, we can increase the amount of lockers. Then, we should expand the volume of lockers and take enough places to store their clothes or books. A good way is change a better lockers system, for example we can change the secret code lockers to be Coin-Operated lockers. That will be more convenient. The student will not be worried about forgetting the secret code. If they wanted to use them, they can put a coin into the locker, and the locker will open, if you close it, the coin will be automatism out. Of course, the coin is a special coin, different coin for deferent lockers. So you will not worried your locker is not safe.

      So we can take an automatism lockers system. For example if the student do not use the lockers for a long time, the lockers system should show through the machines to the staff who manages the lockers. The staff should cancel the using right of the last student and change the key for the other students.

 

 

 

 

Final Conclusion

 

    After taking the Brainstorming session on many problem we finger out that need to be improved, three problems were chosen for consideration. They are the Net speed problem, the Cafeteria system, and the Code-protected Locker System. Although all three problems are worthwhile and familiar with the students and stuffs in the school, we recommend that the Code-protected Locker System Locker System is the most one that needed to be improved. The Code-protected Lockers is very useful, concentrate on and easier to deal with. Therefore, due to these reasons, we have decided to do a case study on this problem in order to discover a new way to make the locker system taking more efficient and convenient with a improved program package. If it has improved, it is the best rewards for our effort.

 

Subjective Recommendation for Top Problem

The Code-protected Locker System is a part of the school storage, and is showing more and more efforts on students¡¯ daily lives. It is a pity that you could not find any place to put the clothes you changed and the books you carry with. Personally our group members suggested changing the lockers systems that both from the software and the hardware, because it is top problem out of the three final vote which could have the easiest way to be solved and affected.
