Software product companies need to envisage the future and adapt to the changing needs of customers to sustain and be successful in an over-crowded market place. When the long-term road map of a product is analyzed closely, product companies often find the need to re-build the existing architecture of a product to facilitate new changes required, and performance tune the product.

Product Re engineering focuses on transforming an existing product in order to reconstitute it in a new form and with new features, taking advantage of emerging technologies, but without major changes to the inherent functionality. The objective of re-engineering a product is to optimize its performance and value to the end-user.

iWork follows a structured method for product re-engineering:
- Understanding the business model
- Listing out the existing features
- Figuring out which features need to be modified or added afresh
- Studying the existing architecture
- Analyzing whether the existing architecture can accommodate the required changes and/or new features
- Re-architecting the product, as needed, towards accommodating additional features or changes
- Testing the re-engineered product and delivering it
- Providing maintenance services.

iWork's software architects have re-architected and re-engineered several ISV products successfully and rapidly, while ensuring that the ISV's existing business model remained secure.
