However I needed valuable inputs on how to start estimating. Ask first, how much staff do you have and how much are you willing to pay or pulling in contractors. How many clients / users do you have for each of those listed systems? >Is there any industry standard or best practice available. Yes, there is only ONE standard, it is named 'No Standard'. You will have to figure out yourself what is the best for you. Perhaps there are IBM-MAIN members who can help you or supply you a product which can do those estimates... >I really appreciate all your inputs in this regard. Please let me know for any >further information required from my end. Ask your vendors. They know their products and can give you a ball-park figure of everything. Good luck.
