2. Technology analysis According to Spacey, John 2017 According to Spacey John is the process of researching technology solutions, problems and risks. It is a component of business analysis that is used to develop requirements, specifications and validate technical designs.business analysis is also an IT operations capability used to identify fixes, improvements and optimizations.

3. The following are common technology analysis techniques and considerations. BenchmarkingBottlenecks Capacity ManagementData Analysis Incident ManagementInformation Technology Risk Non-Functional RequirementsProblem Management Problem SolvingPrototypes Root Cause AnalysisService Management Systems ThinkingTechnical Feasibility Troubleshooting

4.  Based on utilization.  Fast moving.  Slow moving.  Non-moving.  Non-moving items must be periodically reviewed to prevent expiry& obsolescence FSN ANALYSIS items are classified according to their rate of consumption

5. ABC ANALYSIS (ABC = Always Better Control) Selective Inventory Control This is based on cost criteria. It helps to exercise selective control when confronted with large number of items it rationalizes the number of orders, number of items & reduce the inventory.

6. ‘A’ ITEMS Small in number, but consume large amount of resources Must have: Tight control Accurate record Rigid estimate of requirements Strict & closer watch Low safety stocks Managed by top management

7. ‘B’ ITEM Intermediate Must have: Moderate control Purchase based on rigid requirements Reasonably strict watch & control Moderate safety stocks Managed by middle level management

8. ‘ C’ ITEMS Larger in number, but consume lesser amount of resources Must have: Ordinary control measures Purchase based on usage estimates High safety stocks ABC analysis does not stress on items those are less costly but may be vital

9. ABC ANALYSIS (ABC = Always Better Control) Selective Inventory Control PARETO PRINCIPLE About 10 % of materials consume 70 % of resources About 20 % of materials consume 20 % of resources About 70 % of materials consume 10 % of resources

12. Distribution of ABC class ABC class Number of items Total amount required A 10 ％ 70 ％ B 20 ％ C 70 ％ 10 ％ Total100 ％ Using this distribution of ABC class and change total number of the parts.

15. The ABC concept is based on Pareto's law. If too much inventory is kept, the ABC analysis can be performed on a sample. Steps are carried out for the ABC analysis : : Arrange the items in descending order of the usage value calculated above. : Compute the annual usage value for every item in the sample by multiplying the annual requirements by the cost per unit.

16. : Make a cumulative total of the number of items and the usage value. : Draw a graph connecting cumulative % items and cumulative % usage value. The graph is divided approximately into three segments, where the curve sharply changes its shape. This indicates the three segments A, B and C. : Convert the cumulative total of the number of items and usage values into a percentage of their grand totals.

17. VED ANALYSIS Based on critical value & shortage cost of an item – It is a subjective analysis. Items are classified into: Vital: Shortage cannot be tolerated. Essential: Shortage can be tolerated for a short period. Desirable:  Shortage will not adversely affect, but may be using more resources. These must be strictly Scrutinized

20. HML ANALYSIS Based on cost per unit Highest Medium Low This is used to keep control over consumption at departmental level for deciding the frequency of physical verification.
