Chapter 9: Enabling the organization – Decision
making
Managerial decision making challenges
1.
Managers need to analyze large amount of
information
·
Innovation in communication and globalization
have resulted in a dramatic increase in the variables and dimensions people
need to consider when making a decision, solving a problem, or appraising an
opportunity.
2.
Manager must make decision quickly
·
Time is of the essence and people simply do not
have time to sift through all the information manually.
3.
Managers must apply sophisticated analysis
technique, such as Porter’s strategies or forecasting, to make strategic
decisions.
·
Due to the intensely competitive global business
environment, companies must offer far more than just a great product to
succeed.
Operational
Employees develop, control and maintain core business
activities required to run day to day operations. Operational decisions are
considered structured decisions, which arise in situation where establish
processes potential solutions. Structured decision are made frequently and are
almost repetitive in nature.
Managerial
Employees are continuously evaluating company operations
to hone the firm’s abilities to identify, adapt to, and leverage change. A
company that has a competitive advantage needs to constantly adjust and revise
its strategy to remain ahead of fast-following competitors. Managerial
decisions cover short and medium-range plans, schedules and budgets along with
policies, procedures, and business objectives for the firm. They also allocate
resources and monitor the performance of organizational subunits, including
departments, divisions, process teams, project teams, and other work groups.
Types of decision are considered semi-structured decisions, they occurs in
situations in which a few established processes help to evaluate potential
solutions, but not enough to lead to a definite recommended decision.
Strategic
Managers develop overall business strategies, goals, and
objectives as part of the company’s strategic plan. They also monitor the strategic
performance of the organization and its overall direction in the political,
economic, and competitive business environment. Strategic decisions are highly
unstructured decisions, occurring in situations in situations in which no
procedures or rules exist to guide decisions makers toward the correct choices.
They are infrequent, extremely important, and typically related to long-term
business strategy.
Decision-making
process
1.
Problem Identification: define the problem as
clearly and precisely as possible.
2.
Data Collection: gather problem-related data,
including who, what, where, when, why, and how. Be sure to gather facts, not
rumors or opinions about the problem
3.
Solution generation: detail every solution
possible, including ideas that seem farfetched.
4.
Solution test: evaluate solutions in terms of
feasibility (can it be completed?), suitability (is it a permanent or a
temporary fix?), and acceptability (can all participants form a consensus?).
5.
Solution Selection: select the solution that best
solves the problem and meets the needs of the business.
6.
Solution Implementation: if the solution solves
the problem, then the decisions made were correct. If not, then the decisions
were incorrect and the process begins again.
Support: enhancing decision making with
MIS
·
A model is a simplified representation or
abstraction of reality. Model helps managers calculate risks, understand
uncertainty, change variables, and manipulate time to make decision. MIS
support systems rely on models for computational and analytical routine that
mathematically express relationship among variable.
Operational
support systems
·
Transactional information encompasses all the
information contained within a single business process or unit of work, and its
primary purpose is to support the performance of daily operational or
structured decisions. Transactional information is created, for example, when a
customer purchasing stocks, making an airline reservation, or withdrawing cash
from ATM. Manager use transactional information when making structured
decisions at the operational level, such as when analyzing daily sales reports
to determine how much inventory to carry.
·
Online transaction processing (OLTP) is the
capture of transaction and events information using technology to (1) process
the information according to defined business rules, (2) stores the
information, (3) update existing information to reflect the new information.
During OLTP, the organization must capture every details of transactions and
events. A transaction processing system (TPS), is the basic business system
that serves the operational level and assists in making structured decisions.
Managerial support system
·
Analytical informations, encompasses all
organizational information, and its primary purpose is to support the
performance of managerial analysis or semi-structured decisions. Online
analytical processing (OLAP) is the manipulation to create business
intelligence in support of strategic decisions making. Decisions supports systems
(DSSs) model information using OLAP, which provides assistance in evaluating
and choosing among different course of action. DSSs enable high-level mangers
to examine and manipulate large amounts of detailed data from different
internal and eternal sources.
·
What-if analysis checks the impact of a change in
a variable or assumption on the models.
·
Sensitivity analysis a special case of what-if
analysis, is the study of the impact on other variables when one variable is
changed repeatedly.
·
Goal-seeking analysis find the inputs necessary
to achieve a goal such as a desired level of output.
·
Optimization analysis an extension of goal
seeking analysis, finds the optimum value for target variable by repeatedly
changing other variable, subject to specified constraints.
Strategic
support systems
·
An executive information system (EIS) is a
specialized DSS that supports senior-level executives and unstructured,
long-term, non-routine decisions requiring judgment, evaluation, and insight.
·
Consolidation is the aggregation of data from
simple roll-ups to complex groupings of interrelated information.
·
Drill-down enables users to view details, and
details of details, of information. This is the reserve of consolidation; a
user can view regional sales data and then drill down all the way to each sales
representative’s data at each office. Drill-down capability lets managers view
monthly, weekly, daily, or even hourly information.
·
Slice-and-dice is the ability to look at
information from different perspectives. One slice of information could display
all product sales during a given promotion. Another slice could display a
single product’s sale for all promotions.
The
future: artificial intelligence
·
Intelligent system are various commercial
applications of artificial intelligence.
·
Expert system are computerized advisory programs
that imitate the reasoning processes of experts in solving difficult problems.
·
Neural network also called an artificial neural
network, is a category of AI that attempts to emulate the way the human brain
works
