What is the purpose of a contract?

"Procurement and Sourcing teams need to develop commercial models enabling Agile delivery. Putting a price or paying for something when it is not known what will be delivered requires a leap of faith for executives and CFOs to approve. Contracts should be negotiated in an agile way."
-- Martin Stark, IT Strategic Sourcing Manager

What does a Client Service Manager or Purchasing Manager need to know about contracts? What does a Client Service Manager need to know about software development, Scrum and "Agile"? What does a Scrum Master or Scrum Product Owner  need to know about contracting? 

As a customer or supplier of software services at the beginning of a software development project, you know that there is too much at stake to work with just a verbal agreement. Although the Agile Manifesto values customer collaboration above contracts, contracts are often necessary when working with external suppliers, if for no other reason than to ensure a common understanding of what will be accomplished and who will get paid how much by when.

A contract is really just a set of written playing rules. The right rules increase the chance of success for both parties. The wrong rules make cooperation difficult and hinder progress. Which contract forms are best for agile development projects?

Contracts set the basic playing rules for the project. In theory, they are freely entered by both parties to create optimal conditions for successfully completing the project. In practice, contracts are often seen as competitive games in which the objective is to place the other party at a disadvantage, especially if things go badly.

Large companies and governments often have standard conditions which have to be accepted en bloc as a pre-requisite to doing business with them. These conditions are seldom fair, so a reasonable project outcome depends heavily on a good relationship with the actual customer and avoiding recourse to the contract or the law. (The Agile Manifesto is right in this point: customer relationships are more important than written contracts!)

Even negotiated contracts do not always strive for a win-win situation, so you may need the help of experts. However, from the customer’s perspective, contracts produce no added value. They are an artifact of the development process, not something valuable for the customer, so the effort spent negotiating and producing them should be minimized.

A contract defines control, apportions risk and reflects trust between the parties. What happens if something goes wrong? Who pays how much if the project is more difficult than expected? Who benefits if the project is finished earlier than planned?

A contract can have unintended consequences. A contract that is based on invoicing time and materials can create overhead to record, authenticate and, if necessary, defend the amounts claimed. A contract that defines exact roles, especially when more than one supplier is involved, can make it impossible to reorganize to be more effective. A contract that is based on delivering a defined scope can make it difficult and expensive to react to new information during the course of the project.

The wrong playing rules can be detrimental to the success of the project. Bad rules can lead to higher prices, longer time-frames or unrealistic functional expectations. Win-lose games are usually detrimental to project success. Quality most often suffers. Do you want the ‘A-Team’ or the ‘B-Team’ working on your project? Think carefully about how much pressure you put on the supplier.

Sample Definition of Done

Why does Scrum have a Definition of Done? Simple, everyone involved in the project needs to know and understand what Done means. Furthermore, Done should be really done, as in, 'there is nothing stopping us from earning value with this function, except maybe the go-ahead from the Product Owner. Consider the alternative:
Project Manager: Is this function done?
Developer: Yes
Project Manager: So we can ship it?
Developer: Well, No. It needs to be tested, and I need to write some documentation, but the code works, really. I tested it... (pause) ...on my machine. What's wrong with this exchange? To the developer and to the project manager, "done" means something rather different. To the developer in this case, done means: "I don't have to work on this piece of code any more (unless the tester tells me something is wrong)." The project leader is looking for a statement that the code is ready to ship.

At its most basic level, a definition of Done creates a sh…

Explaining Story Points to Management

During the February Scrum Breakfast in Zurich, the question arised, "How do I explain Story Points to Management?" A good question, and in all honesty, developers can be an even more critical audience than managers.

Traditional estimates attempt to answer the question, "how long will it take to develop X?" I could ask you a similar question, "How long does it take to get the nearest train station?

The answer, measured in time, depends on two things, the distance and the speed. Depending on whether I plan to go by car, by foot, by bicycle or (my personal favorite for short distances) trottinette, the answer can vary dramatically. So it is with software development. The productivity of a developer can vary dramatically, both as a function of innate ability and whether the task at hand plays to his strong points, so the time to produce a piece of software can vary dramatically. But the complexity of the problem doesn't depend on the person solving it, just …

Scaling Scrum: SAFe, DAD, or LeSS?

Participants in last week's Scrum MasterClass wanted to evaluate approaches to scaling Scrum and Agile for their large enterprise. So I set out to review the available frameworks. Which one is best for your situation?

Recently a number of approaches have started gaining attention, including the Scaled Agile Framework ("SAFe") by Dean Leffingwell, Disciplined Agile Development (DAD), by Scott Ambler, and Large Scale Scrum (LeSS), by Craig Larman and Bas Vodde. (Follow the links for white papers or overviews of each approach).

How to compare these approaches? My starting point is Scrum in the team. Scrum has proven very effective at helping teams perform, even though it does not directly address the issues surrounding larger organizations and teams. An approach to scaling Scrum should not be inconsistent with Scrum itself.

Scrum implements a small number of principles and constraints: Inspect and Adapt. An interdisciplinary Team solves the problem. Deliver something of va…
