    How to Ask for a Project Extension: Basecamp's Six-Week Rule

    An unfinished project does not deserve another week by default. Here is how to write a project extension note your manager will say yes to, using Basecamp's rule.

    How to Ask for a Project Extension: Basecamp's Six-Week Rule (Updated October 2026)

    Before you ask for another week on an unfinished project, bring your manager a short note: what the extra days will deliver, what you will cut, and when you will stop and decide again. An unfinished project does not automatically earn more time. Basecamp's maker, 37signals, describes this in Shape Up. McKinsey found Indian managers spend 21 hours a week in meetings, so wasted extension weeks are expensive.

    TL;DR

    What is the Basecamp six-week rule?

    The software company behind Basecamp, 37signals, describes a different rule in Shape Up. Big-batch work gets six weeks. The time is decided first and the plan is built around it. The team is also protected from being pulled onto other work again and again. This is an office adaptation for us, not a universal six-week deadline.

    What happens when the project is not finished in time?

    If the work turns out bigger than expected, the team has the right to remove the less important parts. What is delivered must work properly, and other features can be dropped. So you do not have to lower quality to save the deadline. The list of work can get shorter instead.

    Extension note lineExample question to answer
    What it deliversWhat will exist in five days that does not exist today?
    What we cutWhich less important parts are we dropping?
    When we decide againOn which date do we stop and review?

    Why is "just one more week" a trap?

    If the project is not ready after six weeks, it is not guaranteed more time. First stop, rethink the approach, and make a fresh decision on whether to invest further. The company calls this a circuit breaker. The point is that extra time is a new decision, not an automatic right.

    What should a project extension note contain?

    Here is the office scene. The project is stuck, the boss says you have done so much, do a little more. Next week, the same line. Meanwhile the team's next good piece of work never begins. Stopping does not mean giving up. One manager asks, "How much effort have we put in so far?" A better one asks, "If we give five more days, what will we get?"

    How do managers and teams use this in a normal office?

    Give your boss a small note when you ask for the extension. Three lines: what will we get in the next five days, what will we reduce in the scope, and on which day will we stop and decide again. Agree on these first. It shows you respect the team's time and not only effort. Teams I train through our corporate trainings find this note easy to adopt.

    How do you avoid losing next month rescuing last month?

    Managers can make this a habit: set the time for the work first, protect the team from interruptions, and review at the end of the slot. If you are building a leadership habit for your managers, see my leadership training or contact me. I say it in Hindi in the video: "पिछला महीना बचाने के चक्कर में अगला महीना मत गवाइए" (do not lose next month trying to rescue last month).

    Frequently Asked Questions

    What is Basecamp's six-week rule?

    In Shape Up, 37signals gives big-batch work six weeks with protected time. The team can remove less important features to finish.

    Does an unfinished project get an extension?

    Not by default. The approach and further investment must be reconsidered first, which Basecamp's makers describe as a circuit breaker.

    What should I write when asking for more time?

    Three things: what the extra days will deliver, what you will remove from the work, and the date you will stop and decide again.

    Is six weeks right for every project?

    No. It is an office adaptation of one company's method, not a universal deadline. Use it as a way to set time first and decide again at the end.
