The development of the industrial revolution 4.0 in manufacturing has changed conventional business processes to become automated, especially in the furniture sector. The constraints faced by the furniture manufacturing industry are that producers do not have a reporting tool that estimates how many products to sell, goods produced do not match their needs and stock errors. Therefore, the process of extracting needs is an important phase in the development of information systems because it determines the final outcome of the program. The research aims to define system requirements, so that it can help the decision-making process based on real-time data. This study describes the use of system planning techniques in the form of collaborative techniques, observational techniques and contextual techniques, which are combined with the Wellsandt evaluation criteria and measured using the low, medium and high scales. The results of this study are the acquisition of any business process areas that have a high level of difficulty to be prioritized and described in the form of a spider diagram. Implication of this research is that requirements can be used by developers to prioritize areas of business processes that must be improved in making decision support systems.
