IT assignment essay help on: Computer system and program 

Earlier organizations were using legacy system in their work method which was an old method, technology and computer system or application program. There was no method to integrate the working of the business organization and different issues were arising out of this legacy system which took into concern the people, process and application. The owner of the organization did not see any reason to change it. Retraining on a new system was thought of to be costly in time and money. Also, it required constant availability, so it could not be taken out of service. Many did not understand the way it worked. (Wagner and Monk, 2008). Organization is supposed to learn the importance of integration and the way it works for them. Due to the lack of integration, the flow of information could be slow in its processing. If there is no proper integration, the need for interfaces between different software is required. Without the knowledge and proper implementation of integration, different departments in a single organization develop their own computer system, each system working separately using its own data and applications required for the same. Then the departments were supposed to be dependent on each other for the transfer of important information. Output from one department was the input for another department to be processed upon.  Without proper use of integration, the combination between different data of different department could not be carried out easily and correctly. This was one of the main basic problems which occurred out of the lack of integration process. The information does not enter from a proper single source if it is not being integrated with different components required. The information is supposed to flow from a single source and should be able in such a way that it allows management to view the status of the organization’s working scenario. Without the help of integration, it becomes difficult for the management to take decision on a faster basis for the smooth functioning of the organization. Since a single source helps us in reducing the duplicate data, we should try to integrate its working. This all work was done manually so it became slow and unreliable. A number of mistakes occurred which led to the additional problems and complications accruing out of it. Wrong and complicated data travelled through different departments of the organizations (Wallace and Kremzar, 2001).

So these are the basic problems which occur due to the lack of integration and interrupt the free flow of the working of the different department of the organization in concern (Latamore, 1999).

So, to overcome these different numbers of issues, ERP is taken into account. It combines all the different data used by different applications and eliminates the need for interface between softwares (Sharma and Godla, 1999). The main work of ERP is to unite various departments throughout the organization with the help of one single software package. Furthermore, this information could be utilized in a number of ways. It is just a single system with a large well developed database which is there to run all the parts of the business organization and overcome with all the problems arising out of the lack of integration. The legacy system into account was old and was not able to meet the current technical requirements. It was also not at par with the other organizations. So to overcome these various problems, a new system in term of ERP were introduced which was very well able to eliminate the labour intensive manual processes of work. It helped in collection of data in a more better and fast way. Critical business processes concerning all the different departments were streamlined in proper sequence of activities. This resulted into a single database which was much more integrated than the earlier multiple and disconnected one. With this functional specialization, users were able to have a great access to their personal data which helped them in making their own reports and manipulating it as and when required. The self service for the use of data increased to a large extent.  This helped in a better and timely work by people in various departments and their dependency on the work of other people from other or the same department reduced to a very noticeable extent. There are various types of ERP programmes available in the market which a company can use, according to its own needs and requirements. When there is a lot of work done to be carried on by the business organization, ERP works as a very handy or easy to use process. It tells us what is presently going on in the company and what is required to be done for the betterment of the organization as it works as the solid backbone of the organization in concern. It works in a legitimate and transparent manner with each and every data available in the company. Also it takes care of the sensitive and protective data to be secured by multiple security system (Leon, 2007). With the help in the optimization of manufacturing and distribution processes carried on by the company through ERP, company is also able to look forward for new business opportunities available in the market to be grabbed by them in proper time. The ERP program takes care of a number of issues prevailing in the organization. Namely, it could be Financial, Supply Chain Management, Manufacturing, Projects, Human Resources, Customer Relationship Management, Data Warehouse, Reporting, Data Mining, etc (Roman, 2009).

ERP applications provide several benefits including solutions to the problems of legacy systems, reduced development risk, increases global competitiveness, and business efficiency.
