SE Radio 574: Chad Michel on Software as an Engineering Discipline

Requirements

Managing requirements complexity is a critical aspect of software engineering, as Chad Michel explains. He emphasizes the importance of understanding objective complexity, which involves identifying the true goals of a project beyond just fulfilling requirements 1. Jeff Doolittle adds that defects are often most cost-effective to address during the requirements phase, highlighting the need for early detection 2.

The cheapest place to find a defect is actually in the requirements.

Addressing these complexities early can prevent costly errors and ensure that the software meets the actual needs of the customer.

   

Solution Management

Solution complexity management is essential for maintaining agility in software systems. Chad Michel discusses how managing both requirements and solution complexity can lead to greater agility, allowing teams to adapt to changes without major disruptions 3. He stresses that new requirements should not necessitate massive system overhauls, but rather be manageable within existing structures 4.

We want our software to behave much the same way... we should be able to write a new one and put it in there.

--- Chad Michel

This approach ensures that software remains flexible and sustainable over time, accommodating evolving business needs.
