There is usually a trade of information between both technologists. Such technologists are more willing to communicate under such circumstances. Such rates and limits are pre-approved by the client. Business information should not be communicated without a good reason, and if communicated, it should be limited to the specific information on a need to know basis. Technical information is almost always sensitive, and should be protected for two reasons.
Technical information can give competitors an advantage immediately.
Not identifying sensitive technical information that may lead to the development of intellectual property in the form of a patent may jeopardize the patent in the future. One of the ways a patent can be challenged is by showing that the concept was made public before the patent was filed. A nondisclosure agreement signed by the technologists that received the information that specifically identified the concept is the best protection. The statement of work may be a simple description of the task, milestones, deliverables, cost and completion date. The SoW may require a more complete definition of the task in the form of a set of PERT charts.
