The case study conducted by the author in Dindigul District has provided valuable insights for the food/agro processing industries. This paper delineates salient features of Trilogy of constraints faced by Food/Agro Processing start-ups/MSMEs and has also provide SWOT(C) Analysis. Lucid visual presentation with conceptual illustration provides more insights in to the constraints faced by food & agro-processing units along with strategic interventions framework. Key words: Food/Agro Processing Units, Trilogy of Constraints, SWOT(C) Analysis, Taxonomy of Financial, Technology, and Marketing Barriers/Problems.
