Is it necessary to include the clause (have been excluded for the past 5-6 years) if our internal IT dept somehow decide to do software development? But usage/deployment is limited to internal customer. The applications developed are requested by other departments to simplify/automate processes. Will not sell the software. I foresee complications if we decided to include the 7.3 clause without actually selling the "product", i.e. determining and reviewing customer requirements, customer satisfaction, etc. Please advise on how to document 7.3 product design and development without actually selling the product.
