Breaking the Cycle of Budget Overruns: Root Causes o...

I. Inadequate Technical Requirements: Requirements Engineering—The Bedrock of Product Development Requirements Engineering (RE) is the starting point of product development. Its output establishes the project's objectives and serves as the foundation for all subsequent work. Every design iteration must revolve around these requirements, and the final design must validate against them. Ultimately, the success of a product is measured by its degree of requirement fulfillment. The core task of RE is to translate the Voice of the Customer (VOC)—encompassing users, regulations, and internal manufacturing—into objective, quantified engineering language. This process is divided into three critical stages: 1.1 Requirements Elicitation: Finding the "Full Set" The first step is elicitation. The central challenge is: Can we identify all requirements without omission? Goal: Identify the complete set of requirements, not just explicit ones. Methodologies & Tools: Iceberg Model: Visually deriving latent requirements below the surface. Kano Model: Scientifically categorizing requirements into Basic, Performance, and Excitement factors to define priorities. Personas & User Journey Maps: Simulating real-world scenarios to uncover needs that customers themselves may not have realized. Output: Rationalized requirement specifications covering not just functionality, but also environmental factors like temperature, humidity, vibration, and misuse scenarios. 1.2 Requirements Development: Quantified Description and the...
