When planning a business, having a fast and accurate estimation process is crucial.
Of course, if you take enough time and go into detail, you can ensure a certain level of accuracy.
But in reality, the time available for estimation is limited — ideally, we all wish engineers could quickly give us high-quality estimates in just three seconds!
Unfortunately, there’s no such magic.

If estimates are made based on vague requirements, oversights are bound to happen, which often leads to delays in the schedule.
Engineers who are rushed by schedules based on rough, arbitrary estimates will eventually burn out.
And development teams that can’t deliver on time will gradually lose trust.
So, what can we do?

How do we provide cost-effective and accurate estimates within limited time?

In this session, we’d like to share the initiatives and trial-and-error processes we’ve gone through in developing LINE Gift and LINE Shopping.
