Role and Types of Information Systems

In any organization which is operating in modern day business environment information systems have vital and critical roles to play, they are the key drivers in making timely and effective decisions making and help management to better understand and improve their business process and serve the customers better, in other words we can say that management information systems, if designed and used properly, can bring company an added advantage by facilitating decision making and can serve as competitive advantage which is the desire of every organization.

Other role of information systems in modern day organization is to provide the sustainable competitive advantage, in any industry information systems can be a source of competitive advantage in two ways, one is recording and then re-producing the information about customers, their buying behaviors, product preferences with respect to their demographics, this information further can be used to improve product, presenting right product to right customers, and relationship marketing. On the other hand same information can be used my management to make right changes and decision related to business and bring their product one step ahead of competition.

Recommendations for Mobilink Infinity MIS

Mobilink Infinity is market leader in providing Internet and data services in Pakistan, one of the reason of their success is efficient information systems that are in place to facilitate the business processes and help management to make timely and quick decisions, here in the organization different teams are using different kinds of information systems which are independent of each other, these system have different names like for business transactions and customer contact, there is are ISs called Tracer and CRM, for financial purposes they use Octopus & Bond, and for executive and middle management level information needs they have Infinity Analysis Portals. After studying the business processes, their needs of information and information systems in place, author has made few recommendations based on his ideas of improving the information systems and future needs of the organization.

Recommendation 1-Intergration of Consumer Information Systems

One of the core processes that are done on continuous bases and on large amount, is fulfilling the orders placed by customers, these task are done by using two applications, one is Tracer and other is CRM, Tracer is responsible for generating different tasks for different departments like payment collections and installation and CRM is used to provide updated status on their orders and handle their queries and problems, as mentioned earlier, these applications are independent and are not related to each other and used by two different teams.

Here comes the problem, if tracer is down or not working them CRM guys cannot have information, and since information and status of order is entered manually then there is a high chance of customers not getting the required updated information and if information is manually then here are also the chances of errors.

To avoid such errors it has been recommended that consumer related information systems should be integrated so that times, cost and errors caused by manual integration can be avoided and organization can save their resources and can serve the customer better.

Recommendation 2-Intergration of Financial Systems

The financial information system should also be integrated with consumer systems, since Octopus is handling the payments made by corporate and residential clients these payment status are manual updated in CRM and Tracer, this process causes two kinds of problems, one is the manual entries for updating of records causes human error and there has been cases where customer has to suffer because non-payments suspends the services and such incidents cause customer dissatisfaction and a bad word of mouth and cause company cost in terms of time and image.

The other problem caused by this process is related to time and resource costs that redundancy of entries and data cost the company in terms of resource time and allocation of two teams for entering the same information. To avoid such situations organization should integrate this part of financial system with consumer related systems so that customer suffering and organization cost can be saved, since company is expanding its business and growth in number of customers, the probability of such incidents is high, so such integration is highly recommended.

Recommendation 3-Decentralization of Database

Infinity’s main data base is located in Egypt, where the other Orascom Telecom ventures also have the databases at the same location, now having operations in Pakistan and database in Egypt is cause of certain inefficiencies that are source of customer sufferings.

If database is down in head office then operations in Pakistan get disturbed and applications fail to respond to queries, more over the holidays systems in Egypt is different from Pakistan and there has been cases where support related to databases were required and support staff was on leave because of the vacation in Egypt, having database on remote locations and not been able to give support is major cause that customer suffer and timely information is not available to management.

It have been suggested that company should have their database located in Pakistan so that timely support can be given if required. Same is the case with the application development and application support, since these two tools are also developed in the head offices and support is also provided from the same location, this cause in delays in business operations and information needs. Cases have been reported where delays were caused because of the errors in applications and there support from the host country. To avoid such situations in future it has been suggested that databases and their application development and support should be located in Pakistan.

Recommendation 4-Redefining User Rights

Company’s businesses are growing and so is their customer base and operational complexities, but the user right in every information systems were defined long ago and there is no modification and up gradation, with the growth of business the nature of information rights required by the users are changing, now every user demands for cross sectional viewing of information and if such information is not present in their information system then this cause delays in business operations and employees are unable to serve the customer in efficient way.

For elaborate this we shall take the example of financial information system and CRM, CRM is suppose to update the customers regarding their account status, but employee dealing with CRM is unable to view the payments status either by their CRM application or the financial information application, what they have to do is to manually get the information from the concerned department and this practice causes delays in serving customers which is either visiting their service center or are on call.

Since there in not integration in the information systems, such processes are causing delays, pace of growth in customers requires the company needs to study the entire systems and redefine the rights required by the users, now the employees dealing with customer should be able to view at least the basic information regarding the customer account on different dimensions. This will be vital in improving the customer service level at hence increase the customer satisfaction and eventually leads to competitive advantage.


Author has, in this assignment, review the theoretical knowledge on managing information systems and have looked on that how information systems can affect the strategic management of business and improve the decision making, further the information systems of selected organization have also been studied and their functional usage by different management levels were also studied, moving forward author has also made some suggestions that can improve the effectiveness of information system deployed by the organization not only now but in future also.
