University: Logistics and Operations Management Report: TAT Reduction

This report delves into the critical aspects of Logistics and Operations Management, specifically focusing on strategies to reduce Turnaround Time (TAT). The analysis centers on the application of the cause and effect diagram, also known as the fishbone diagram, as a key Six Sigma tool to address the issue of high TAT. The report outlines a four-step approach using this technique, including identifying the root causes of delays, analyzing contributing factors, and evaluating performance. It emphasizes the importance of understanding the reasons for defective parts, optimizing information flow, and resolving warranty issues. The report further discusses the significance of inventory management and inter-departmental linkages, proposing the R&O model for improvement. By applying cause and effect analysis, the report aims to minimize TAT and enhance overall operational efficiency, referencing several key academic sources to support its findings.

Critical Discussion and Application of the Technique
The given case study has identified the significant ways to reduce the overall TAT which
is taken into consideration with increasing working hours for the existing staff. However, a more
comprehensive approach to ensure the reduction in the overall turnover time with the appropriate
six sigma tool will be observed with the implementation of cause and effect analysis. A cause
and effect diagram, also known as the fishbone diagram will be able to solve the problem in four
steps (Sin et al. 2015).
Firstly, this technique will be able to identify the problem responsible for the high TAT.
Secondly, it will work out with the important factors associated to the problem, identify the
possible reasons and getting a clear view for the cause of problem. This will be also able to
identify the exact reasons for the slow response of shop orders from Singapore. The evaluation of
the cause and effect diagram will consider the rotable support and ensure more quality in the
R&O shops. The identification of the performance and service level of the TAT will be further
able to observe the competitors strategy in a more effective way. Some of the other significant
consideration with reduction in the turnaround time from 47 days to 30 day needs to be taken
into account with understanding of the reasons for producing more number of defective parts. It
is important to understand the reasons for delay in receiving the defective parts. The organization
will be able to decide on the appropriate distribution policy by confirming the reason for the
issues in the production process (Pyzdek and Keller 2014).
The cause and effect diagram will be also able to consider the various types of the
problems in the R &O information flow. This will be considered with knowing about the
engineering scope of work, getting the customer approval and estimating the overall cost. The
resolution of the warranty issues will be also able to significantly contribute to reduce the overall
TAT. The application of cause and effect diagram will be able to identify the time taken for
information exchange in the different types of the department for the customers and
administrative TAT. The application of the cause and effect diagram will be also able to identify
the motive of higher waiting time for the assembly technicians in the receiving the parts
(Goetsch and Davis 2014). The delay in the time spent needs to be also analysed as per the lack
of spares like rivets and blades. In addition to this, maintaining the stock of inventory will help in

the assessment and know about the different types of the concerns related to essential parts
requirement for the inventory. The TAT is also observed to be dependent on the inter-
departmental linkages which will be duly addressed with the application of the R&O model.
Several types of the other manufacturing facilities will be also able to know about the clear
targets with the TATS. Henceforth application of cause and effect analysis in the said ways will
help to minimize the TAT (Conger 2015).
