I am not very clear about your query as you didn't mention the preamble. However I would like to suggest something that may be relevant to you.
Do you have any Industrial exposure?
1. If yes , then you should concentrate on the existing problem/ process in your area wherein the application of TQM improve/enhance the existing process through your method. To know the various applications/ methods/ trends then you must go through the available literatures/ Research Papers. You need to review the available literatures and next identify the best solution that may be applicable to your process/ problems. Consolidate the results/ outcomes.
2. If not, then you must select your area of interest, identify the problem area through relevant literatures review/ Survey through specific sample. Narrow down the best solutions that may optimise the concerned process/ reduce problems in your selected sample. Carry out your analysis with available analysis tools/ simulation/ models and consolidate your results/ outcomes.
3. The various area wherein you can explore further through TQM are:
A. Improvement of current process (in your specific area)
B. Cost Optimisation.
C. Waste Management/ Improvement.
D. Reducing of errors/ improvement of margins.
E. Working Environment.
F. Resource Management.
G. SCM enhancement.
H. Lean Management
I. Application of Taguchi method
J. Human Resource
K. Enhancement of operations.
L. Industry 4.0
M. Simulation models
N. Mathemetical models
O. Check for data science/ AI/ e- based solution platforms.
