Delivery dates are often stigmatized as stressful and arbitrary, but they can actually help teams stay focused, aligned, and driven while keeping project scope in check. Crafting effective engineering deadlines requires setting a realistic date by agreeing on the project scope, estimating work involved, and breaking down milestones with achievable targets. Adjusting project scope and managing uncertainty are crucial, as estimates should have error margins to account for new information or changes, and teams should consider personal commitments when planning timelines. Clear engineering deadlines can transform how teams work, allowing them to ship quality product on time and make progress towards their goals.
