We propose a new requirements elicitation method in the domains of ERP, CRM, and SCM by using specifications of several existing package software. We have analyzed the requirements elicitation processes of experienced analysts in a specific domain, and found that they clarify requirements by referring the specifications of existing packages that seem to be satisfied with customer's needs. This process can be formulated into two subprocesses: 1) package selection, where an analyst compares the customer's needs with functions/nonfunctions of packages and selects the suitable candidates of packages; and 2) requirements evolution, where he examines the selected packages with his customer and an approved part of specifications of packages are added into their requirements. The proposed method, called PAORE (package oriented requirements elicitation method) is designed based on the analysis. We applied this method to a simple but realistic example of Web-based sales supporting system and assessed it.

This paper presents an extended version of the goal-oriented requirements analysis method called AGORA, where attribute values, e.g. contribution values and preference matrices, are added to goal graphs. An analyst attaches contribution values and preference values to edges and nodes of a goal graph respectively during the process for refining and decomposing the goals. The contribution value of an edge stands for the degree of the contribution of the sub-goal to the achievement of its parent goal, while the preference matrix of a goal represents the preference of the goal for each stakeholder. These values can help an analyst to choose and adopt a goal from the alternatives of the goals, to recognize the conflicts among the goals, and to analyze the impact of requirements changes. Furthermore the values on a goal graph and its structural characteristics allow the analyst to estimate the quality of the resulting requirements specification, such as correctness, unambiguity, completeness etc. The estimated quality values can suggest which goals should be improved and/or refined. In addition, we have applied AGORA to a user account system and assessed it.

Experts in requirements elicitation interview stakeholders using various levels of knowledge to grasp and elicit users' requirements. This paper analyzes expert interview processes and explores a computation model for simulating them. This model can be used to navigate a novice analyst's interview processes. It consists of a blackboard model and a state transition model in order to narrow the candidates for questions that an expert analyst will ask stakeholders next in the interview process. The candidates are selected based on information that has been elicited from stakeholders, and the blackboard model is for holding this information in the form of IEEE 830, a standard form of requirements specification documents. We have analyzed experts' interview processes and constructed a computation model in the sales management domain. We also recorded novice processes and showed that we could improve them by means of the model.

We describe a fundamental and important activity named "Specification Generation" in the specification process which generates a specification from requirements, the output of the prior requirement process. We propose a new mechanism of specification languages which moderate requirements adding, deleting and changing. It follows our consideration concerning characteristics of requirements and requirements process. More concretely speaking, we provide a module operation mechanism of specification languages. The mechanism modifies modules and resolves conflicts which occur in case of the module operation if needed. Although we realise the mechanism by enhancing a multi sort functional language, we claim that the mechanism can be generally applicable to any specification languages which have modularity because the key issue of the mechanism is not "functional language" but "operation on modules".
