Information System (CS507)
support system (DSS) typically provides a spreadsheet style "what if?" analysis capability, often for only one
department or one product at time.
CBIS from Functional View Point
CBIS can be divided into subsystems based on how the users are grouped in the organization. This
grouping of users is in terms of related tasks that are performed. These conceptual systems are mirror
images of physical systems that are present. These systems are collectively called Organizational
Information systems (OIS).
12.1 Organizational Information Systems (OIS)
The term OIS views organization as a combination of process oriented groups whose information needs are
related but independent. All functional systems should work together for problem solving since each system
specialises in specific domain of information.

12.5 New Dimensions in MKIS
Through extensive use of computers in marketing field, newer concepts are emerging in marketing field,

o  Call Centres
Customer Relationship Management
Information System (CS507)
Businesses increasingly talk about fostering relationships with their customers. This is important
because some modern businesses have literally millions of customers. Hence keeping personal touch
with every individual customer is getting difficult to achieve.
Companies are clearly eager to nurture relationships with their customers. Businesses need to
understand the extent to which consumers want to engage with their brands. For some
businesses there is
  Either a strong natural need ­ banks
  Or an emotional attachment ­ Fashion retailer, car manufacturer
Benefits of CRM
Maintains and enhances customer base
Encourages customer loyalty
Gaining more customers' wallet-share
The more effective a company's customer retention and defection management strategy, the
less they need to plug the gap with new customers, who are expensive to recruit.
 CRM help in establishing communication to encourage customers to share information about
Tastes and preferences
Interests in Co's brand extension initiatives
CRM is a business strategy that goes beyond increasing transaction volume.
Its objectives are to increase profitability, revenue, and customer satisfaction.
To achieve CRM, a company wide set of tools, technologies, and procedures promote the relationship
with the customer to increase sales.
Thus, CRM is primarily a strategic business and process issue rather than a technical issue.
Reasons for adopting CRM
Customers now prefer to execute transaction in an electronic environment through online-trading.
Also the establishment of customer services centers has also removed the inconvenience to access
vendor's physical locations.
Due to absence of physical contact, companies are curious to keep a soft touch in an efficient manner.
This requires keeping a customer-wise online track of past correspondence and transactions.
CRM reduces cost of sales and distribution by
Targeting advertising to customers to increase the probability that an offer is accepted.
Using web applications to decrease the number of direct sales people and distribution
channels needed
Managing customer relationships rather than manage products (a change in marketing)
CRM minimize customer support costs by
Making information available to customer service representatives so they can answer any
Information System (CS507)
Automating the call centre so that representatives have direct access to customer history
and preferences and therefore can cross-sell
12.6 Key CRM Tasks
Customer Identification -- Identifying customer through
Marketing channels,
Interactions overtime,
Customer Differentiation ­ Segregating customers, with respect to.
Their lifestyles
Perception about Co.'s products
Customer Interaction ­ Efforts made to retain customers for long-term profitability and relationship.
Customization / Personalization
"Treat each customer uniquely" is the motto of the entire CRM process. Through the personalization
process, the company can increase customer loyalty.
12.7 CRM Issues
Customer Privacy
Customer privacy is an important issue in CRM. CRM deals with large amounts of customer data
through various touch points and communication channels. The individual firm is thus caught in an
ethical dilemma ­ collecting as much information as possible but still respecting limits for personal
Software issues
There is little standardized technologies and protocols for CRM implementation in the market.
Vendors publish new versions of CRM software as frequently as they can thus adding to client's
expenses. CRM software requires highly integrated environment for high productivity, which is rarely
Sales Force Automation

Customer account management,

marketing machines.
12.8 Call Center
Due to its direct contact with customers, call center is widely gaining popularity. It refers to a department
within a company or a third-party organization that handles telephone sales and/or service. Call centers use
automatic call distributors (ACD's) to route calls to the appropriate agent. In addition to a call centre,
collective handling of letters, faxes, and e-mails at one location is known as a contact centre. As computers
gain more and more involvement in marketing field, presence of a highly efficient and integrated call center
has become inevitable. Call centers should have direct access to every customer's track record so as to help
them handle queries in an efficient manner. Modern day call centers, record the telephonic conversation
with the customers, extract a summary of it, and display it every time the customer calls so as to help
attendant review entire record.
Call Center-Challenges
Call centre agents are challenged daily to navigate disparate, non-integrated applications as they attempt to
resolve customer service requests. The call centre should offer an integrative solution so that customers can
be responded efficiently. Call canter should help cut long processing times which add to customer
frustration and dissatisfaction with the company.

o  Planning, development and maintenance of production facilities
o  Establishment of Production goals
o  Availability of production materials
o  Scheduling
