Service Management

Answer:

A major city of Country SE, SA has a population of 150,000 approx. It has a student population of 12,000 approx. SH maintains a monthly record of her law department and finds recent increase with the readings of this year.
Run charts are used to record changes in a process variable with respective to time. They are used to determine trends, cycles or performance of any process either to interpret trends or to compare present and future trends of a solution.
Using run charts, determine the trends of law department as shown below:
Construct run chart on each incident categories as follows:
From the above constructed run chart, it can be found that there exists a significant increase in the incident of burglaries from the month of August to December. This drastic increase might would illustrate that burglaries are attempted by gangs. In order to interpret the trend of illegal activities, SH has considered the increase in burglaries.
Scatter diagram visually represents the relationship between two variables. Plotting possible-cause variables against the present problem variables will help to identify the correlation that exists between the variables. In the present case, possible variables that can be plotted against burglaries would be the previous or next year's data of other gang activities of the respective months.

Answer:

The PDCA cycle is a process of continuous improvement of processes and products. The PDCA cycle consists of four wheels Plan, Do, Check, and Act. As a competitive strategy, the low cost leadership helps to reduce cost of manufacturing goods and gain market share. The main objective of low cost leadership is to produce a qualitative product at a minimum cost.
Through step by step analysis, the PDCA cycle helps to set a competitive strategy of low cost leadership as discussed below:
PLAN : Planning refers to the recognition of problem, analyzing the possible causes, and develop an action plan. For low cost leadership strategy, the main objective is to manufacture at a minimum cost. The various alternatives to minimize the cost need to be analyzed to find the best alternative. An action plan need to be developed to implement the chosen alternative. Thus, planning helps to define an optimal strategy for low cost leadership.
DO : The solution need to be implemented at this step. The strategy chosen at the first step need to be implemented and monitored. Monitoring the progress helps to find whether the strategy has been implemented as planned.
CHECK : At this step, the results of new plan are reviewed and evaluated. The progress of the new strategy need to be evaluated to find whether it has bought any positive change. This helps to note the unpredicted consequences that arise and minimize them.
ACT : At this step, the progressive changes are standardized if they are profitable and beneficial. The low cost leadership strategy that is progressive should be communicated to all workers with enough training if needed. This helps to keep all the workers aware of the new strategy implemented and work according to the new strategy to achieve objectives.
Thus, by the application of the structural PDCA cycle, a low cost leadership strategy helps to give a tough competition among rivals in an industry.

Answer:

Data Envelopment Analysis measures the efficiency and productivity rate of an organization with respect to multiple output and inputs used in the production process.
Some of the weaknesses of DEA are as follows:
• Measurement of error can be problematic.
• DEA does not measure the exact or absolute efficiency.
• DEA method fails to solve complex problem.
• DEA method is complex and difficult to understand especially when the problem consists of number of variables.
