I. Introduction
I am working as marketing manager under supervision of Mr. Tuan, Director of
marketing department.
My company is Da Nang Furniture Company Limited (DFC) is a young
SME firm which manufactures furniture for domestic and overseas markets. DFC markets its
products not only in Vietnam, but also in foreign markets such as EU, North America, Japan, and
Southeast Asia. With the high technologies, high quality finishing, safety standard and it is
becoming the best choice for customer, so the demand of DFC products is growing rapidly.
Besides that, the main materials are purchased from Vietnam and neighboring countries - Laos
and Cambodia. This is the reason why the company has to calculate carefully in order to achieve
its competitive advantage.
In this report, I will show about the forecasting method. It is the method the company can
use for predicting in next months. Besides that, I will review and evaluate inventory control
systems and prepare a spreadsheet to assist in finding optimized order size for discounted price
range provided by supplier. Then, I will do a Material Requirement Planning (MRP) for all
components using a spreadsheet. To construct a network diagram and determine the expected
completion time together with the critical path as construct a Gantt chart for Planning to
purchase a new product. Moreover, I use NPV (Net Present Value) and IRR (Internal Rate of
Return) methods to evaluate feasibility of proposed investment projects.

Actual Sales and forecast ed sales (movingaverage-Addtive method
According to the line graph, the sales tend to increase year-by-year. The number of
furniture sales increased into 2011 and 2012 with about over 55,000 units to nearly 61,900 units.In July, 2011, the number of units for sales is lowest with lower than 55,000 units while in
March, 2012, it is the highest for selling furniture of company with 75,000 units. It means, the
company had good plan for 8months. About forecasting next five months, it can be said that the
sales can be improved with interest in program in autumn. The highest rate can guess over
75,000 units while the lowest just 65,000 units. It is good advantage for sale furniture.

Actual Sales and forecas sales(Moving average-Multiplicative
method)
The Multiplicative method is very similar to Additive method, except for calculating
seasonal percentage instead of calculating seasonal variation. So, it is the same units for selling.
It is just difference about 0.01. The products will sell in next five months which was forecasted
same Additive method.

The additive method is a good method since that it forecast the sales which are almost
close to the trend. In other words, if the trend line goes up, the forecasted sales will also increase.
The additive it is better because it has smaller Forecasting error It means it will help find the
error clearer and easier to repair the error.

3.5 Management Information Systems
Since DFCs sales and exports grow, there is an urgent need for effective cooperation and
information sharing among departments. It is increasingly important for DFC employees to
share company information such as production, delivery schedules, sales forecasts, financial
information, inventory, and labor requirement across the departments - production, marketing,
finance and export. Currently, all the departments share the information using paper-based
reports and memorandum. At DFC, data for each department are kept separately on their
respective personal computers (PCs). Sales forecasts from marketing departments are
forwarded to production department using memorandum. Raw material orders from
production department are forwarded to purchasing department using the same method. There is
a lack of utilizing appropriate Management Information Systems within the organization as well
as with external stakeholders.
There are seven types of information system including Management Information System
(MIS), Executive Support Systems (ESS), Management Support Systems (MSS), Decision
Support Systems (DSS), Knowledge Work Systems (KWS), Office Automation Systems (OAS)
and Transaction Processing Systems (TPS). The following figure has displayed properly about
the levels, types and functions of each level.
To solution, a business will have several Transaction Process Systems such as: calculate
and system these things that we need know and tax that we have to pay, each store should have
cash machine and cash register to make the sale easier. They need Office Automatic Systems,
Kinh Do can apply it because it coordinates diverse information workers. Especially, it will try
to improve the productivity of employee who need to process data and information. Moreover,
the company can use Word process such as Microsoft Word, Power point or Microsoft Excel XP,
with this system, their employees can improve quality work of every employees working in an
office or can accept work at home. Moreover, the company should trains employee to improve
about their skill, should have email of each manager to update information for employees. Each
office should have notice board and reward board to make employees can follow mission and
have more motivate to do their work. Each store, the company should add more staff to
introduce about product for customers with enthusiasm, friendly and funny.

company has to order in week 2 is include 570 bed site, 7000 slat (2cm), 90 roller. If in week 2,
the company can meet this material, they can next to week 3. In week 3, they need site assembly350 beds 670 rest sides and 2520 slat (1cm). In week 4, they just need side assembly 360 rests. In
week 5, they also need 600 hinges. After that, in week 6, to complete 400 folding sun loungers,
the company has to have 3200 wood screw. If the company can meet all of this planning for

3.9 Investment AppraisalAccount rate of return (ARR) the profit arising from a project as a percentage of the initial
capital cost.
Payback period: the method is forecast about the time that company can get back the money.
With 3 projects, I choose two methods follow.
NPV( net present value) it calculates the present values of all items of income and expenditure
related to an investment at a given rate of return.
IRR(internal rate of return) a method which determines the rate of interest(the internal rate of
return) at which the NPV is 0. IRR method will indicate that a project/ investment is feasible if
the IRR exceeds the minimum acceptable rate of return.
