When comparing alternative solutions to see which one best meets the design criteria, you will often use a Weighted Objectives Chart (WOC) or a decision matrix of some kind. In order to evaluate the solution alternatives fairly and in an unbiased way, it is important to devise a way of evaluating the designs before they are created, or before you finalize those design alternatives. The criteria that go into a WOC should be based directly on the objectives you defined in your problem definition, and may include additional objectives that will help you measure the effectiveness and desirability of each solution alternative. Then, you build or chose the design alternatives to best fit these criteria. Creating a weighted objectives chart entails several detailed steps:
Here's what I have for a Weighted Objective Table:
|Criteria (Weighting) Informatica PowerCenter IBM Infosphere DataStage AWS Glue Speed (25%) 18 20 22 Scalability (25%) 22 21 23 Multi-region Support (20%) 16 15 20 Security Measures (30%) 27 26 25 Total (100%) 83 82 90
Rationale for the Weighting: Speed and scalability have the most significant weights, as these directly impact PDI's ability to perform real-time data analysis and handle a growing volume of data. Security Measures have been assigned the highest weight due to the crucial need to protect sensitive data. Multi-region support carries slightly less weight as PDI has already been operating internationally using its current ETL software.
Now give me this Weighted Objective Table in the format and description that I have provided above?
Certainly! Here's the Weighted Objectives Table for comparing alternative solutions to the problem of selecting a data integration software:
Criterion (Weighting) | Informatica PowerCenter | IBM Infosphere DataStage | AWS Glue |
---|---|---|---|
Speed (25%) | 18 | 20 | 22 |
Scalability (25%) | 22 | 21 | 23 |
Multi-region Support (20%) | 16 | 15 | 20 |
Security Measures (30%) | 27 | 26 | 25 |
Total (100%) | 83 | 82 | 90 |
Speed and Scalability (50%): Speed and scalability have been assigned the most significant weights (25% each), as these directly impact the system's ability to perform real-time data analysis handle a growing volume of data efficiently.
Multi-region Support (20%): This criterion represents the software's capability to operate across multiple regions. Although important, it has been assigned a slightly lesser weight due to PDI's existing international operations using its current ETL software.
Security Measures (30%): Security measures, such as data protection and access controls, have been assigned the highest weight (30%) due to the critical need to safeguard sensitive data.
This weighted objectives chart allows for a fair and comprehensive evaluation of the alternatives based on the defined criteria, ensuring that the chosen solution best meets the organization's objectives and requirements.
