ビジネスアナリスト(BA)は、鉄道チケットの起動システムの有効性を分析する責任があります。BAは、2日間(月曜日と水曜日)の予約担当者の観察に基づいてレポートを作成しました。
収集された情報によると、予約係は十分に活用されておらず、顧客を待つために多くの時間を費やしています。BAは次に何をすべきですか?
正解:B
Explanation
The BA should not rely on a single source of data or a limited observation period to draw conclusions about the effectiveness of a system. The BA should conduct further analysis to ensure that the data is reliable, valid, and representative of the actual situation. The BA should also consider other factors that may affect the demand for the ticket booking service, such as seasonality, promotions, customer preferences, etc. The BA should use a variety of techniques, such as interviews, surveys, data mining, etc., to gather more information and confirm or refute the initial findings.
