THE RELEVANCE OF COMPUTERS IN MANAGEMENT INFORMATION SYSTEM.
(A CASE STUDY OF NITEL PLC ENUGU)
ABSTRACT
Management information system is network of communication channel in an organization from the points of data origination through the processing procedures to the decision making (feed back) then from the point of decision back through the information channels to the points of implementation of the decision (control).  This suggests that management information system is indispensable to any organization.  Is crucial role toward organizational development demand an effective and efficient mode of operation.  The attainment of this objectives necessitate the utilization of computers on data processing and dissemination of information.
Computerization of the management information system facilitates timely dissemination of information to management for decision making enhances accuracy in data manipulations and makes for speedy information flow within the organizational structure.  This is the purpose which this study seeks to bring to fore.  With particular reference to the billing system of NETEL Enugu, the researcher wishes to show how the computerization of the system has facilitated customer identification, customer billing, vetting and bills distribution in such an efficient   manage by which customer service have tremendously improved in the light of productivity and profitability.
In furtherance of the research objectives recommendations were made, which if implemented, the researcher hopes will bring about efficiency and effectiveness’ of organizational operations in general and decision  making in particular. making in particular.

INTRODUCTION
1.1 BACKGROUND OF THE STUDY
It is said that to mange on organization is to manage its future.  How can the future be management? The answer through a timely procurement of relevant  and reliable information is the complement of its procurement.  The whole lot of activities therefore ranging form information procurement through its collation validation and analysis to feedback make up what can be seen as a system.  The type of system in management is known as management information system (MIS)
Management information system is the formal processes of data collection organization analysis processing and dispersing of information internal and external to the organization in an effective and efficient manner (LUCEY 1987) it entail not only any organized and interacted approach at placing relevant and timely information on the desk of  the manager to aid decision making   (Modile 1995) but also the control and accessibility any plant on time as may be demanded by management.
Primary the MIS. is set up for the purpose of providing planned and controlled information to all levels of management to effect appropriate decision making  This it does by gathering data imputing and  processing them into information and further disseminating these  items of information to managers in the from of financial as well as non financial information system can be subdivided into functions information system such as marketing information system the financial information system and the present information system and so on depending on the type of organization.
 How does the management information system organizations serve various level a of management.  The answer is not for fetched for instance for the lower management  concerned with the day to day process of supervision and direction of the routine activities of the organization, whose decision are often repetitive with short time horizon and few uncertainties, the MIS provides operational information which are mainly historical detailed largely and narrow in scope.  Also it provides and direct the operations and function of the organization.  Finally, to the top management, organization as a whole in addition to the formulation of objective the development of strategies, policies  and  tactics that are to be adopted in achieving organizational goals the MIS provides strategies information which are largely external, forward looking and mostly qualitative.
This, the management information system (MIS) provides management with varying information depending on the level thereby making for increase on the efficiency of the organization through better management decision, more effective utilization of resources increased profits betters and less costly administration.
a)    MIS performs four basic functions collection of data from a variety of sources.  This means obtaining facts such as records of the day transactions of the organization either by observation or research from both external and internal source.
b)   Efficient organization of data accessing and storing data in database.   A database  is on organized collection of data.  For instance, an ordinary hand written address book is an example of a simple manually maintained database.
c)       Data procession into information upon which is to be used by management. Data is stored, analyzed compared, calculated and generally worked on to produce message in the from required by the manager, which is then termed information.
d)      Presenting data in a meaning and useful from.  This could be by mans of various kind of reports including stoical reports such as sales analyses and control information such as budget variance  reports.
 These functions, the MIS can performed either manually or with the aid of machines many organizations manually operate their management information system and due to the enormous quantity of data/information are being used lot paperwork is involved.  In tray (documents) serve as input for data white reports and statement sheets form the output.  Filling cabinets where in records and files are kept, serve as the device for storing information.
However owning to the fact that organization have grown in size, the information flow has become so enormous that face to-face. Communications and even written memoranda can ob longer effective adequate communication or effective processing of data.  The MIS of these organizations have this in recent times found it difficult to meet with the increasing demand being made on it for information. As a result, the manual means of operation is jam packed with scores of data to be processed.  Hence Delng  and in accuracies in data collection and analysis.  Delng often makes decision making to be on accurate. Also, there is the problem of misappropriation of important documents or even cases of stolen files.
These lapses amongst others have put a question make on the manually assisted MIS, hence, solutions have been sought in the introduction of mechanization with particular inference to the use of computers.
 1.2       STATEMENT OF THE PROBLEM
Investigation has shown that before introduction computers in the MIS department of NITEL PLC, Enugu, the manually operated MIS indicated lapses which often beat the imagination of managers.  Consequently the processes of decision making was almost reduced to guess work due to the absence of an effective and enduring information and retrieval  system.  this affected the general productivity of NITEL.
However the computerization of the MIS department, not only was the problem of competence in decision-making achieved but also information storage and retrieval systems become effectively.  But has NITEL PLC been fairing well with the computerization of its MIS? The colossal financial loss by the parastatal  via unpaid telephone bills and other fraudulent practices have thrown a spanner in the wheels of NITEL and has justified the prickle of Cursed by the researcher upon which satisfaction the research sought by asking the following question.
a)             Has the computerization of the MIS department of NITEL PLC Enugu actually improved management operations and decision making?
b)             Are customers effectively and satisfaction served better now with the computerization of NITEL’S department?
c)             How fraud been mitigated in NITEL PLC?
d)            Since The Computerization on the MIS department has the profitability level of NITEL PLC been in a progressive fraud?
These are the problems which this work seeks solve
 1.3       OBJECTIVE OF THE STUDY
THE OBJECTIVE OF THE STUDY ARE
1)        To ascertain the extent to which computer information helps to solve the problems of the manual system.
2)        To find out those areas on which management of computerization firms have failed to take advantage of the service of the computer within the organization well as analysis area.
3)        To identify a frame work for analyzing a company with a computerized management information system with a view to deduce the benefits or otherwise in taking such decision.
4)        To determine the operational performance of the computer system with particular reference to MIS department of NITEL PLC Enugu and the problem associated with the use of machine
5)        To make necessary recommendation
 1.4       SIGNIFICANCE OF THE STUDY
The satisfactory operation and control of an organization rests to great extent on information or data.  Data processing for business purposed is not an in itself but is used by management to assist in achieving its objective is of  providing goods and services making prior dealing fairing with employees customer, suppliers and satisfying legal requirements regarding the keeping of records.  This could be enhanced by the introduction of the computer in the management information system.
This project will highlight the  importance of computers in the management information system and heighten the emphasis by comparing the computerized system of operation to the manual.
Whereas this work appears to be more beneficial to those persons with sapient knowledge of management process will find valuable          
1.5       SCOPE OF THE STUDY
The scope of this study is only confined to the MIS department of NITEL PLC Enugu  with particular reference to the designated area of MIS which control customers billing system.  The adopting of the billing system will help in providing the relationship between the billing system and the profitability level.
