Color
Most of the mobiles are in black color, it is too common. Actually, I love red, so I am looking for a red mobile with high specifications.
Control
It is convenient to use touch to control the mobile when you are browsing web-site, editing photos, but it is a bit clumsy in typing words. I wish a mobile can get dual control, touch and Keypad.
Material
The touch of steel is really better than plastic, and steel is not easy to destroy.
- Allocate Weights to Criteria
After I listed out all the specifications I desired, I have to give priority to each of the specification according to my preference. The preference is affected by my personality(control method), perception(the image of mobile, color, shape), family pressure(the money I can spend on mobile), social trend(color, outlook, brand) etc..
Here is my priority:
Brand > Outlook > Color > Camera > Material > GPS > Screen > Connection > Control > Price
- Information Search
After I got the priority of the criteria, I have to do an information search to find out which mobile in the market is suitable for me. The search can be done in the following sources (Prioritized):
- Commercial Sources
It includes advertisement, promotion booklet and salesperson. The information from commercial sources is the most reliable. Advertisement includes TV advertisement and magazine, newspaper advertisement. If I got any question about the mobiles, I would ask the salesperson for details, as the salesperson hold the firsthand information. The related booklets are attached on the last page.
- Experiential Sources
Use the mobile in the flagship-shop. First-hand experience will tell the mobile is suitable for you or not.
- Public Sources
It includes mass media and consumer-rating organization. I always browse the forum to see whether the product is good in comment before I buy the electronic goods. User’s comment is a good reference, but it is not 100% reliable. The related links are in the last page.
- Personal Sources
I will also ask my friends comment if they got the mobile that match my preferred specifications, but this situation is not always exist.
The following page is the mobiles I selected after information search.
Table1: Mobiles I selected
- Evaluation of Alternatives (Calculation)
After doing the information search, I got some selected mobiles in hand, now I have to value the mobile according to the specifications I preferred.
Table 2: Evaluation of Alternatives
# Price is from SingTel
# Specifications are from the Promotion Booklets attached on the last page
Obviously, SAMSUNG I8910 HK earns the highest mark 7. And the second choice is LG GC900, it earns 6 marks.
- Select the Best Alternative
The best choice is SAMSUNG I8910HD as it earns the highest mark.
- Purchase Decision
If there are no unexpected situational factors that arise when I am about to act on the purchasing decision, such as bad attitude of the salesperson, the target mobile out of stock etc., I will surely purchase the SAMSUNG I8910HD.
- Post-purchase Evaluation
To check whether the purchase decision satisfies my expectation or not. If I am not satisfied, I may have to repeat the process again and find out the problems.
Conclusion:
After A-H decision making processes, the best choice for me is SAMSUNG I8910 HD, it can satisfy most of my needs.
- Explain the usefulness of Pareto Analysis as a tool in inventory management. Illustrate its applications.
Introduction:
ABC Analysis divides on-hand inventory into three class based on the total cost. It is an inventory application of Pareto principle. The Pareto principle states "critical few and trivial many". It means few items represent almost 80% of the total cost, and these items are grouped into Class A, they are the most important items in the organization; the "trivial many" can be divided into two groups, Class B, which represents 15% of the total cost, and Class C, which represents 5% of the total cost. Class B and Class C items are less important as they only represent 20% of the total cost.
After the items are classified into different groups, we are going to find out the holding month of the items. It is important in operation management as longer the holding period, higher the holding cost and will cause lots of problems. The holding cost includes rent for the store room, carrying cost and stock management cost. There are also problems of products expire, products out-of-date and no cash in hand. So, it is not a good idea to holding too much stock. We have to make an Inventory Decisions to manage the inventory effectively.

# accurate to two decimal places
Table 4: ABC Analysis
# accurate to two decimal places
Table 5: Class A Item Holding Months
# accurate to two decimal places
Every-organization will keep about 3 months stocks to meet consumer's demand and prevent shortage, it is a holding reference. Over 3 months holding months, it will cause the problems in the above.
Item Y1's holding month is 2, it is acceptable and it is good to keep few months stocks, nothing special.
Item I9's holding month is 12.75, it is over 4 times than the holding reference. For any reasons, 1 year holding stock is totally not acceptable and the problems of expire and out-of-date should be arisen. There should be some problems of inventory decision and the operation management. A further detailed analysis should be followed as 1 year stock holding will cost a lot.
Item X2 and H8's holding months are 8 and 9.13, it is longer than the reference, so it is not acceptable. To prevent the product expire, it is better for the organization to held some special sales, for example, 30% discount or buy one get one free. Although it may cause loss as the selling price is lower than the production cost, the loss will be smaller than when the products are expired or out-of-date.
To conclude, 3 items out of 4 in Class A are longer than the reference holding month, the operating system of the organization obviously fails to work. It is a must to find out the problems or even re-organize the operation system, change the staffs if needed. If not, the organization will be shuttled down soon as capital deficit.
Table 6: Class B Item Holding Months
# accurate to two decimal places
Item M8’s holding month is 3, it is equal to the holding reference, and it is acceptable.
Item C2’s holding month is 8.07, it is too long, organization should find a method to sell all the product out quickly. The most effective method is reducing the price, advertisement also can help. If the products still cannot be sold, the organization may decompose it and use the materials to make new products. Or, the organization can donate all the stocks to the charity, it can higher the reputation of the organization.
Item C3’s holding month is 5, it is 2 moths more than the reference holding month. If there is a reason for the 5 months holding, such as Lunar Chinese New Year sales, expected shortage in the following months etc., then 5 months holding period is acceptable, if not, we should find out the problems of long holding period and reduce the holding stock.
Item W2’s holding month is 1.07, it is normal.
In conclude, the stock holding situation is acceptable,2 items’ holding period are within the holding reference, but it is not very healthy, the organization should seek to shorter the holding month.
Conclusion
Pareto Analysis is a very powerful tool to manage the inventory, it shows the holding month of different items clearly and the organization can take corresponding actions.
The average holding month for both Class A items and Class B items is 6 months, it is double amount of the holding month reference, 3 months. And in Class A, there is an item, I9’s holding month is over 12 months, it cannot be accepted. The organization should re-organize the operating system and change the managers or re-train them. Also, they should learn how to make inventory decisions. Basically, inventory decision includes “What items to hold in stock”, “What quantity to hold in stock” and Reorder Point.
“What items to hold in stock” refers to the organization should choose the right items to hold in stock. For example, organization should hold more the best-selling products. Organization should hold the seasonal product in corresponding period. If the organization expected there will be a shortage of product or increase in the production cost, then the organization can hold more stocks. It ensures the organization have products to sell.
“What quantity to hold in stock” means organization should recognize what quantity of different products should be hold. It can be done by take average from previous sales volume.
Reorder Point refers to when should you order the products. Normally, organizations are recommended to reorder when the product remains 1/2 in stock, because ordering and transporting the product takes time. Order the product too early will cause over stock and not enough space to stock the product. So, an accurate reorder point is important for any organizations.
