Dear Richa,
Fixed Assets and Inventory both are completely different subjects. Secondly, in both the cases there is no "evaluation" as such. Rather there can be audit, either of fixed assets or inventory.
Please clarify on the task that you are going to handle.
Audit of the fixed asset becomes easy provided company has maintained "Fixed Asset Register" properly. First check whether this register is maintained or not. If not then first develop this register. This will be a big task for you.
As far as inventory is concerned, account reconciliation is one thing and physical stock verification is another. Please clarify what you will do.
Thanks,
Dinesh V Divekar
