Dear Khushi,
I think at primary level, training needs can be finalized based on industry as well as business plans. For e:g in construction industry there is Sales Department, Construction as well as Liaison, Procurement (Purchase) dpt. Sales people required effective communication skills, functional skills for construction team like M.S.Project, 3 D Max, Nano Technology etc. for Service departments like Accounts & Finance you can go for yearly seminars etc.,
TNI can be related to revised business plans. If your organization has decided to implement ISO or ERP, so all employees may get trained for the same. In special competencies mentioned above, you can go for TNI. I may help you for further TNI form or process or Training Calendar format. Please feel free to contact at "swapnapawar99@gmail.com"
