For its handful of major annual decisions, Eli Lilly's leadership team has a rule to never make a final call in the initial meeting. This process intentionally builds in time for reflection, debate, and persuasion.

A Complete Response Letter (CRL) from the FDA due to manufacturing issues can destroy a biotech. CEO Ron Cooper warns leaders to invest heavily in Chemistry, Manufacturing, and Controls (CMC) early, even when the cost exceeds the clinical trial spend. This early investment in professionalizing CMC is critical to de-risk the company's future.

To predict a project's success, move beyond lagging indicators like schedule and budget. Instead, monitor leading indicators like the rate and "stickiness" of decisions, the stability of interfaces between subsystems, and how proactively risks are surfaced and addressed. These day-to-day factors determine the ultimate outcome.

Contrary to typical agile discovery, projects in high-stakes environments benefit from starting with extremely strict processes and documentation. This establishes a compliant foundation. Flexibility can be introduced later, once core requirements and constraints are fully mastered, rather than starting loose and adding rigor.

Agency leaders often delay decisions for fear of being wrong, creating significant opportunity costs and mental distraction. This paralysis is more damaging than the risk of an incorrect choice. Any decision is better than indecision because it provides momentum and learning, a lesson especially critical for small or solo-led agencies.

To ensure a smooth transition from development to production, an operations or manufacturing SME must be part of the design process from the start. Otherwise, products are developed without manufacturability in mind, leading to expensive, reactive fixes and subjective quality control during scale-up.

Instead of arguing for more time, product leaders should get stakeholder buy-in on a standardized decision-making process. The depth and rigor of each step can then be adjusted based on available time, from a two-day workshop to an eight-month study, without skipping agreed-upon stages.

Categorize decisions by reversibility. 'Hats' are easily reversible (move fast). 'Haircuts' are semi-permanent (live with them for a bit). 'Tattoos' are irreversible (think carefully). Most business decisions are hats or haircuts, but we treat them like tattoos, wasting time.

To build a product with confidence, ensure every technical decision—down to the smallest resistor—has a clear lineage back to a user or business need. This creates a highly defensible architecture where the 'why' behind each part is understood, eliminating risky assumptions and aligning the entire team.
