This case study describes the development of an Enterprise Information System (EIS) for an ISO 9001 manufacturing firm. The system is built using rapid application development tools with the method known as extreme programming. An overview of the EIS development process, the system design goals, and a chronological narrative of EIS development are presented. Included are additional requirements and recommendations for those considering agile methods.

Agile programming techniques have revolutionized software development, providing a flexible and efficient approach that prioritizes user collaboration and rapid delivery. In this case study, we explore how these methods were applied to develop an Enterprise Information System (EIS) for a manufacturing firm, showcasing the benefits and challenges encountered during the process.

An anonymous manufacturing firm recognized for its precision and rapid delivery developed a new EIS. With annual sales between $5-$9 million and a workforce of 60-90 employees, the firm needed a system that could handle complex job estimations, real-time resource monitoring, and compliance with ISO 9001 standards. The existing system, a patchwork of outdated technologies, was inadequate for the firm’s evolving needs. The development team implemented agile techniques, specifically extreme programming (XP), to create a robust and adaptable EIS.

The existing information system was inefficient and fragmented, consisting of a Unix-based mainframe, Excel spreadsheets, and Access applications. This setup led to delays, errors, and a lack of real-time data visibility. Job estimation inaccuracies often resulted in financial losses, and the absence of a streamlined resource monitoring system made it challenging to manage labor and key processes effectively. Furthermore, maintaining ISO 9001 certification required extensive documentation and reporting, which the current system could not support efficiently.

The firm's competitive edge was at risk due to the limitations of its existing system. Misquoting projects led to significant financial losses, while the inability to monitor resources in real time resulted in operational inefficiencies. The lack of integration between systems caused redundant data entry and errors, frustrating employees and increasing the administrative burden. The pressure to maintain ISO 9001 certification added to the strain, as the current system could not adequately support the required documentation and reporting processes.

To address these challenges, the development team employed XP principles, focusing on small releases, continuous integration, and user collaboration. They began by prioritizing job estimation, creating a collaborative method for quoting new work that incorporated lessons from past projects. Next, they developed a real-time resource monitoring system to track labor and key processes, ensuring timely adjustments based on current conditions. The EIS was designed to be user-friendly, with extensive employee input to ensure cultural compatibility and minimize training time. ISO 9001 compliance was built into the system, with automated monitoring and reporting features. Throughout the process, the team used agile techniques such as pair programming, refactoring, and coding standards to maintain high-quality code and facilitate rapid development.

The implementation of agile programming techniques transformed the firm's operations. The new EIS provided accurate job estimations, reducing financial losses and improving project profitability. Real-time resource monitoring allowed managers to make informed decisions quickly, enhancing operational efficiency. The system's compatibility with ISO 9001 standards ensured seamless compliance, reducing the administrative burden. Using agile methods resulted in a robust and adaptable EIS that met the firm's needs and supported its strategic goals. The success of this project underscores the value of agile programming techniques in developing complex enterprise systems, demonstrating their potential to drive efficiency, quality, and innovation.
