Real and financial options
Jun 08, 16 min read by Olav Maassen Whether people realise it or not, "freedom to choose" is the underlying principle behind many of the agile practices. We call this principle Real Options. An understanding of Real Options allows us to develop and refine new agile practices and take agile into directions it hasn't gone before.
Real Options also help us understand why some people resist some of the practices. To use a familiar phrase, Real Options is about "deferring decisions to the last responsible moment," which is an explicit principle in the Lean Software approach.
CIMA F3 - 9 Real options
By avoiding early commitments, you gain flexibility in the choices you have later. A more formal definition will follow.
Types of real options[ edit ] Simple Examples Investment This simple example shows the relevance of the real option to delay investment and wait for further information, and is adapted from "Investment Example". Consider a firm that has the option to invest in a new factory. It can invest this year or next year.
To illustrate this let's look at some agile practices and point out where commitments are avoided as long as possible. These are just a few examples.

Once you become aware of Real Options you will discover a lot more.

Behaviour Driven Development and Test Driven Development provide many options, especially "the option to change the software, knowing when you have broken it.
In other words, test driven development removes the need for design commitments, the choice of design can be deferred until after the coding has started. More subtly, Test Driven Development allows the developer to know with certainty that they have finished, instead of determining beforehand when the programming is done.
Contact What is real options theory? Definition and meaning Real options theory is a modern theory on how to make decisions regarding investments when the future is uncertain. Real options theory draws parallels between the valuation of the financial options available and the real economy. The theory has become a popular theme in most business schools across the world, as well as the boardroom, especially within oil companies.
Test driven development requires no decision at all, simply stop coding when all the tests are green. Similarly mock objects allow the developer to defer the decision on how to implement a class until a later time when they have more information on what is real and financial options from the class.
They also create a nice recursive implementation pattern.
So What are Real Options?
XP and Scrum defer the decision about which story to develop until just before the coding starts. This allows the team to incorporate information that arrives at the last moment, such as a new client request. The Scrum Backlog provides a forum where any idea for functionality can be recorded without requiring an immediate commitment to build it.
At the project Chris is working on, the development is prioritised based on client requests. In effect, sales drive the prioritisation process by stating the relative importance of a client. The team doesn't start working on a feature until the clients have requested it.
- A real option is an economically valuable right to make or else abandon some choice that is available to the managers of a company, often concerning business projects or investment opportunities.

Now the team waits real and financial options see what the clients actually request. By delaying commitment on the features built, the team is able to reduce time-to-market for new features requested.
When the client requests a feature the team is free to act, because they are not tied up working on unwanted features.
This is only possible with short iterations and a fast turnaround on regression testing. Pairing provides options in that more than one developer will have an intimate knowledge of any part of the system.
This mitigates the "truck number" a. The truck number is the size of the smallest set of people in a project such that, if all of them get hit by a truck, the project would be in serious trouble . By spreading the knowledge of the system the project is not in danger when anyone on the team wins the lottery.
Viewing Agile through Real Options
So What are Real Options? Real Options is an approach that allows people to make optimal decisions within their current context. This may sound difficult, but in essence it is a different view on how we deal with making decisions.
There are two aspects to Real Options, the mathematics and the psychology. The mathematics of Real Options, which is based on Financial Option Theory, provide us an optimal decision process .
The psychology of uncertainty and decision making based on Neuro Linguistic Programming  and Cognitive Behavioural theory tells us why people do not follow this optimal decision process and make irrational decisions as a result. Financial options are options written and stock and shares.
A huge amount of mathematics has been developed to price and risk manage these options. Real Options are real world decisions. Much of the existing literature explains how we can use the Black Scholes formula to price real options.
