   Organization generally face more than one problem at a time problems complete for manager attraction. For the best care resources of the organization.

   3. Generating alternative solutions :- This step would be to generate flexible alternative to the problem. Manager should not take any major decisions without exploring all the possible alternative.

   Generating a number of alternatives allow demon to richest the the Temptation of finding a speedy solution to the problem.

   4. Evaluating alternative:- Alternative should be evaluated in order to see how effective it would be full stop generally there are 5 criteria on the basis of which alternative are evaluated flexibility quality acceptability cost and ethics.

   Alternate tips that do not seen flexible should not be considered any further.

   5. Selecting an alternative:-It involves selecting the best alternative.

   Three basic user approaches by managers are

   1. Experience

   2. Experimentation

   3. Research and Analysis

   6. Implementing the decision:- Implementations of selected alternative must be properly to achieve the objective. It is possible for good decision to become the effective due to poor implementations.

   7. Monitoring the decision :- Managers are required to monitor the process of implementations of the decision so as to make sure that everything progressing according to plan.

7. 6. Explain Waterfall model with a diagram. 

   Answer:

   Waterfall model:- In this model each phrase must be completed before the new phrase can being and is no overlapping in the phrases.

   Waterfall approaches is divided into separate phrases

   The outcome of one Press Act as the input for the next phase of sequentlly.

   Requirement:- the first phase involves understanding with lead to decide and what it function purpose etc. Here the supreme vacations of the input and output for the final product are studied and marked.

   System design:- system design is prepared and specification from the first phase are studied in this phases.

   system design helps in specifying hardware system requirement and also help in defining overall system architecture.

   Implementation:- with input from system design the system is first developed in a small program called units which are are integrated into next.

   Integration and testing:- all the unit developed in the implementation and integrated into system after testing of each unit.

   Software designed need to go through consistent software testing to find out if there is any e error does not face any problem during the installation of the software.

   Deployment of system :- the product is deployed in the customer's environment once the functional and non functional testing is done.

   Maintenance:- after installation maintenance take place. It involves making modifications to the system for an individual component to attribute to improve performance.

   So this is a complete Waterfall model with diagram and different phrases.

8. 7. What are the application of financial mis?
