Abstract
In software development projects, problems are often caused by ambiguous project scope. Especially, the description of the contractual documents tends to become inadequate in the contract with the customer whose experience in software development is insufficient. In these cases the requirements of the customer would not be clearly described in scope statement, and the misunderstanding of the description will cause troubles afterward. To reduce such troubles, it is effective to promote the project by scope definition through the negotiations with the customer. The negotiations include comprehension of the customer's organization and technological level, identification of the key player, description and explanation concerning specification according to the customer's level, and strategy to remove customer's uneasiness.
