In general, experimenting with models requires less time and is less expensive than experimenting with the real object or situation. A model airplane is certainly quicker and less expensive to build and study than the full-size airplane. Similarly, the mathematical model in equation (1.1) allows a quick identification of profit expectations without actually requiring the manager to produce and sell x units. Models also have the advantage of reducing the risk associated with experimenting with the real situation. In particular, bad designs or bad decisions that cause the model airplane to crash or a mathematical model to project a
$10,000 loss can be avoided in the real situation.
The value of model-based conclusions and decisions is dependent on how well the model represents the real situation. The more closely the model airplane represents the real airplane, the more accurate the conclusions and predictions will be. Similarly, the more closely the mathematical model represents the company’s true profit-volume relationship, the more accurate the profit projections will be.
Because this text deals with quantitative analysis based on mathematical models, let us look more closely at the mathematical modeling process. When initially considering a managerial problem, we usually find that the problem definition phase leads to a specific objective, such as maximization of profit or minimization of cost, and possibly a set of restrictions or constraints, such as production capacities. The success of the mathematical model and quantitative approach will depend heavily on how accurately the objective and constraints can be expressed in terms of mathematical equations or relationships.

... The time required to prepare these data and the possibility of data collection errors will make the data preparation step a critical part of the quantitative analysis process. Often, a fairly large database is needed to support a mathematical model, and information systems specialists may become involved in the data preparation step.
Model Solution
Once the model development and data preparation steps are completed, we can proceed to the model solution step. In this step, the analyst will attempt to identify the values of the decision variables that provide the “best” output for the model. The specific decision-variable value or values providing the “best” output will be referred to as the optimal solution for the model. For the production problem, the model solution step involves finding the value of the production quantity decision variable x that maximizes profit
In order to address the above components, five decision making steps have to be put in place, these are; being attentive, being intelligent, being reasonable, being responsible, and being reflective. The first step, being attentive, involves evaluating the whole situation and coming up with the data and information about the problem at hand. In so doing the following questions are viewed; what facts to bear in mind, what direction to take so as to get the expected solution, and what is the main issue to work on. In the second step, being intelligent, the information is clearly studied to determine whether the collected data is revealing the correct details concerning the problem. Determine the stakeholde...

An objective is the desired or needed result to be achieved by a certain time. In the Community Center I observation one classroom with three to five years preschool outside of the playground. There was a tire tube swing and one teacher is pushing the children. The color of the tire tube was red and round. There was a basketball court in the playground and three boys playing. There was a toy bear that a boy was carrying around in the playground. There was a purple ball child with happy face on it. There were four girls ridding horse on the ride. Four boys were wearing shorts; 10 girls with blonde hair. The playground was filled with flowers with six tires around playground. There were 10 tricycles in the play area, and four chi...
An objective is a specific step, a milestone, which enables you to accomplish a goal. Setting objectives involves a continuous process of research and decision-making. Knowledge of yourself and your unit is a vital starting point in setting objectives. Strategic planning takes place at the highest levels; other managers are involved with operational planning. The first step in operational planning is defining objectives - the result expected by the end of the budget (or other designated) cycle. Setting right objectives is critical for effective performance management. Such objectives as higher profits, shareholder value, and customer satisfaction may be admirable, but they don't tell managers what to do. They fail to specify priorities and focus. Such objectives don't map the journey ahead - the discovery of better value and solutions for the customer. The objectives must be focused on a result, not an activity, be consistent, be specific, be measurable, be related to time, be attainable.

Make the decision through the integration of ideas and data, and negotiation and prioritization of ideas
The basic aspects of the decision making process. First the problem is defined, relevant objects are observed and classified, measurements are taken of their activities and data are collected in a database or file so that the decision maker can understand the problem. From this data, functional relationships are develop from various patterns and predictions, or inferences are made. Criteria are selected for decision making and for enlisting various alternatives. From these criteria a decision model is used to select the best or most satisfactory alternatives or course of action. Management action is then taken. Finally, an accounting system is used to measure the outcome of the action and to feed the results back into the decision process for management to make the next decision. In some case, many of these processing steps are automated. In other case, they are done by the decision maker based on the information provided by the accounting information system and computer software used to assists management in the decision making process. Throughout the decison making process are communication channels through which information flows, and there are numerous feedback loops for more information on the results of actions and its bearing on future decisions.
Data Collection is the process of collecting information that will be utilized in the diagnostic process and eventually used to make business recommendation. In this data collection process, it is critical to ensure the highest quality of data possible. In the data collection component, the information is gathered on the specific department or organization such as inputs, design components, an...
