Así lo he visto traducido.
Ciertamente, de acuerdo al contexto no se refiere al papel en sí sino a la calidad (algo burda) del trabajo a mano alzada.

Description
A 'brown paper' exercise, is so called as it uses a large scale format to map an existing business process, with an emphasis on being 'rough and ready' rather than a precise, neat and tidy document. Applied to the product development process, it encourages a shared understanding of the implications of new product introduction on different parts of the business and helps to generate a shared ownership of the process. It is likely that the process map will illustrate the complexity of the NPI process and demonstrate critical flows of information, key check points and areas of over (or under) bureaucracy. The output is intentionally physically large, which can be daunting at first but aims to bring the process to life (see illustration).
