From a contracts standpoint, where vendors are bidding against blocks of Story Points, this has huge implications. There is no “wrong” Story Point estimate. And who’s to say that the estimates are inflated? Story Points are team-specific. Even if they must inflate their estimates to do so. Teams with Story Point quotas (goals) will almost always hit them. Story Points are easy to manipulate: Because Story Points are subjective and relative (no connection to hours), they’re quite easy to manipulate. So, on paper, a junior team that delivers less value may appear to be more productive because they complete more Story Points. But a points-based procurement incentivizes the delivery of Story Points, not value. People conflate Story Points with value: More experienced teams tend to estimate work items as fewer Story Points than their junior counterparts. There are a number of issues with the points-based procurement approach: The problem is - Story Points do not equate to value. The intent of this approach is to abstract away the specific solution requirements and team composition, and instead focus only on the value that can be delivered. So, Story Point estimates are relative and subjective, factoring in the unique blend of experience and skills on that specific team.įive years of the Agile Institute: Our top lessons learned read more Another team might look at that same work item and conclude that the effort is much greater. Keep in mind, the basis for comparison (the 1-pointer) is relevant just for the specific team that analyzed that work item. Another key distinction is that Story Point estimation happens continuously, throughout the execution of work, instead of just once, at the start of a project. Unlike the traditional estimating approach, where an architect might generate all the estimates, with Story Points, the team doing the work is the one estimating. All three of these factors drive the overall effort required to fully implement that work item. When analyzing work items, teams consider the volume of work, complexity, and risk/uncertainty. A work item sized as 2 Story Points should be twice the effort of the 1-pointer. Every other work item is then sized relative to that original work item. They call it 1 Story Point and use it as their basis for comparison moving forward. To define a Story Point, a team identifies a simple, straightforward work item that can be completed quickly, usually in less than a day. First, what’s a Story Point?Ī Story Point is a “ unit of measure for expressing an estimate of the overall effort required to fully implement a piece of work.” Yet, one popular approach is doing more harm than good – points-based procurement, or buying Story Points. Over the years, a number of contracting approaches have emerged to resolve this conflict. This idea contradicts how traditional contracts are often set up, with vendors handcuffed to the Iron Triangle of cost, scope and schedule. In the Agile Manifesto, it’s conveyed as Responding to change over following a plan. Since the dawn of Agile, contracting officers have sensed a disconnect between traditional government contracts and Agile delivery methods.Ī central tenet of Agile is – You can’t know all the requirements at the start of the project.
