Extracts from this document...




There is a need to acquire a new computer system to bring substantial benefits to the company in the modern business arena.

Report To: Members of the Board of directors


This report is about the need to upgrade the new computer systems for our company.  It also discusses the advantages and the disadvantages of both the old system which is currently used by our company and the new system available at present.  The aim is to bring substantial benefits to the company by using a new computer system which supports multiprogramming and virtual memory.  This is because quality of our products and services are very poor when compare to other companies which are using new computer systems such as Multiprogramming and Virtual Memory.  There are several disadvantages and constraints appear in our current system.  And also the current system is now nearly out of date and may fail to work properly.  The maintenance cost is increasing and the quality of service which the system provides are decreasing.  For these reasons it is time to analyze the current system and to introduce the new system very soon.  

The current system (Single User Batch System)

The current system is using old technology called the batch system.  It is used by several years all over the industrial countries and was very famous.  Its growth brought many changes in the industrial world and human’s working style.

  • The sales catalogue of products and services used to price customer orders is often out of date.  In particular, new items and services are not catalogued immediately and items which are now no longer stocked still appear.  The problem is located in the time-consuming nature of the batch system used to prepare the catalogue from the inventory records.
  • Customer requirements are sometimes difficult to deal with as records of orders are unable to access immediately on time.
  • Orders that cannot be immediately satisfied from current stock and production that is, back orders are not processed consistently.
  • Due to the large number of documents flowing through the system the time taken to process an order may be days, even if all the goods are held in the warehouse.
  • For some kind of huge jobs it takes time in hourly rate or days.  Consequently large number of employers could not able to finish their job within one day as a result they can not carried out other jobs and  unable to meet their deadlines.
  • Data within the system is generally stored in a way which makes it difficult for management to retrieve useful information.  For instance, regular reports are time-consuming to produce and are often late, rendering them ineffective for control purposes or to aid medium-term strategies.
  • As a result company’s all the processes are carried out in very slow rate and unable to provide quality service for our customers.

It is very clear now the multiprogramming and the virtual memory techniques are provides high quality for the computer system and they provides substantial benefits for low cost.  And also the multiprogramming and the virtual memory technologies are very popular and used by several companies.   Furthermore they have many advantages and could not find any disadvantages when compare to our old batch system. Batch system is now uncommon and if we continued with the current system our company may face massive lost in our market.  The new system with multiprogramming and the virtual memory will increase the quality of our service and productivity.  These developments sought not only to increase the number of tasks completed per unit of time but also to increase the efficiency of hardware usage on single tasks.  Furthermore by using new system our market can be extended across the world and can maintain the steadiness. I believe that it will be a forwarded and reasonable movement of our company’s history and necessary to do now.
