Over the last decade, the trend for customers is to buy code and not only the software resulting out of it. At the same time as code becomes the product its quality is being questioned and becomes subject to quality measurement. Requirements are being applied to the source code itself. To support flexibility, readability and independency for the customer, tools verify the code quality and have been directly impacted by the contract hence the payment. Checkstyles, coding conventions, class cycling and documentation are essentials to sell a good source code, creating a value for the customer.
