Decision Analysis and Resolution

QMS Training

2


Objective

To ensure systematic decision making in all the scenarios where several alternatives exist

and an appropriate decision is sought for.

Mahindra Satyam Confidential

3


Process

Identify scenarios where Structure Decision is required

Identify the Decision Making Technique

Make the Decision

Define Criteria for Selecting Alternatives

Identify Alternatives


4


Identify Scenarios

Identify scenarios where structure decision is required Possible scenarios provided in PP template

– Technology Selection for the Project– Design Architecture Evaluation – Selection of tools to be deployed in the project– Make/Re-use/Buy

Other scenarios where structured decision analysis process can be applied are: – When the decision is related to topics assessed as being of

high or medium risk– When the decision could cause significant scheduling delays– When the costs of the decision process are reasonable

compared to the decision’s impact.


5


Identify Decision Making Technique

Select decision making technique to be used. The possible techniques are Pugh Matrix Brainstorming QFD Delphi

The recommended technique is Pugh Matrix


6


PUGH Matrix

Following are the steps to construct a Pugh Matrix Determine a weight for each criteria. One of the weighting methods is to use

weight levels that sum to 10 or 100 giving higher numbers to more important criteria and lower numbers to less important criteria. Another method is to assign relative weights ignoring the sum that results.

Multiply the rating of an alternative by the weight assigned and sum across all criteria. Divide this sum by the sum of the weights. The result is the composite rating for the alternative.

Alternate solutions are evaluated using the identified decision making technique and appropriate solution is selected

The selected solution is then implemented


7


Identify Alternatives

For every instance of DAR, list of all the possible choices is made

– including the choice of doing nothing, if required recorded in the technique template identified [e.g.: PUGH matrix or QFD

template] for decision-making


8


Define Criteria for Selecting Alternatives

Determine evaluation criteria - for the identified scenarios, decide the evaluation criteria for making a decisionSome generic evaluation criteria are Impact on cost Schedule Performance Efficiency Risk strategies


9


Evaluation Criteria

Decision Scenario Evaluation Criteria

Technology Selection for a project

Availability Interoperability Modularity Adaptability Scalability Portability Extensibility Reliability Maintainability Conformance Security Long Life


10


Evaluation Criteria


Design Architecture Evaluation

Data Design Architectural and

component level design User interface design Technical issues Security Restrictions or Limitations Portability Scalability


11


Evaluation Criteria


Selection of tools to be deployed in the project

Completeness Usability Platforms / Installations Reliability and Robustness Consistency Recovery mechanisms Functional Specifications Product reputation & industry acceptance Support availability Licensing options Customization Documentation quality


12


Evaluation Criteria


Make/Re-use/Buy related decision scenarios

Productivity Quality Performance Risk Factors Strategic advantages Payback Infrastructure Training


13


Evaluation Criteria

For Organizational decisions some of the evaluation criteria could be Potential Impact on company performance Ease to Implement Cost / Benefit relationship Speed of implementation Acceptance by stakeholders Negative impact on environment


14


Make the Decision

Based on the evaluation of the alternatives, most appropriate solution is identified Customer is approached in situations where the decision/solution impacts the

customer PM approves the decision based on the analysis Record the decision taken and all required details in the DAR Record template


15


Objective Met

All scenarios where Structured Decision Making is required are identified DAR Techniques are used to achieve the desired result
