Dear Thangavel Raj,
Though you have raised the query on the company assessment, you have not provided information about the company's nature, finished product, who will conduct it, or the purpose of the assessment.
Since you mentioned that the assessment will be "with or without the finance department," I do not believe it is related to a merger or takeover.
Potential Departments for Assessment
The assessment could cover various departments such as Operations, Quality, Sales, HR, etc.
Strategic Tools for Assessment
Alternatively, strategic tools like Porter's Five Forces, SWOT analysis, McKinsey's 7S, and others can be utilized. These tools help evaluate the strategic capability of the organization.
Thanks,
Dinesh Divekar
