Why Agile Still Needs Planning: Insights from a Large‑Scale Scrum Project

In a large‑scale, multinational Scrum project the team’s mantra “because we are agile, we don’t need a plan” led to unclear requirements, resource gaps, and avoidable risks, prompting the question of whether agile truly eliminates planning.

The author cites a previous article that clarifies the biggest misunderstanding: waterfall focuses on executing a fixed plan, while agile does not discard planning but adapts it.

Regardless of delivery method, the four project fundamentals—scope, resources (cost), time, and quality—must be defined. Business stakeholders need to know the budget and timeline up front.

Through two years of practice the author concludes that for projects with complex dependencies, an upfront plan is mandatory, but it should be continuously reviewed and adjusted rather than rigidly executed. The plan provides the budget and resources that enable agile’s adaptive execution.

Under agile principles the key factors are reframed as:

Scope – focus on defining the Minimum Viable Product (MVP).

Resources (cost) – estimate the required money and personnel.

Time – map dependencies, identify the critical path, and know what needs to be done when.

Quality – break down requirements, instantiate them, and prepare acceptance test cases to close the delivery loop.

The author emphasizes that a vague but correct plan is better than a precise but wrong one; flexibility around business goals is more important than exactness, echoing the analogy that a compass is more valuable than a map.

These conclusions also apply to product development: without money, people, or a realistic timeline, nothing can be delivered, and stakeholders must understand the investment needed.

In summary, planning is indispensable for any project or product; it need not be exhaustive or perfectly accurate, but it must answer the questions of cost, resources, and duration, while agile methods provide the mechanisms for iterative, goal‑driven delivery.
