Free your superstar developer team, and leave the Auth to us. 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.

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 required from the class. They also create a nice recursive implementation pattern.

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.

Viewing Agile through Real Options

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. Now the team waits to 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 [1]. By spreading the knowledge of the system the project is not in danger when anyone on the team wins the lottery. So What are Real Options? Real Options is an approach that allows people to make optimal decisions within their current binary options what is. 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 [2]. The psychology of uncertainty and decision making based on Neuro Linguistic Programming [3][4] 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.

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. Real options differ thus from financial options contracts since they involve real i. Key Takeaways A real option gives a firm's management the right, but not the obligation to undertake certain business opportunities or investments. Real option refer to projects involving tangible assets versus financial instruments. Real options can include the decision to expand, defer or wait, or abandon a project entirely.

Real Options are real world decisions. Much of the existing literature explains how we can use the Black Scholes formula to price real options.

BOOKS BY DR. JOHNATHAN MUN

Fisher Black and Myron Scholes along with Robert Merton are Nobel Prize winning economists who invented an equation to value financial options. Unfortunately, most of that literature is wrong when applied to Real Options. We cannot price real options using Black Scholes' famous equation. Whereas a PhD or Masters in financial mathematics is required to derive Black Scholes or prove the statement we just made, method of real options is addition understanding of maths is required to use the results of these maths.

The "only" things that the Financial Option maths can tell us about options are: Options have value.

So What are Real Options?

Options expire. Never commit early unless you know why. Quite simply, the maths tells us not to make a commitment until the last minute unless we know with certainty why we want to make the decision early.

Sound familiar? The "Real Option" decision process is not new. Preston Smith was one of the first to coin the phrase "Make the commitment at the last responsible moment" [5]. However, whereas Preston's statement was an opinion method of real options is addition upon many observations, Real Options are based on financial mathematics. In the Summer ofwe ran a series of sessions on Real Options. Without understanding the psychology, most attempts to implement a new decision process will fail.

Choices Given any decision to be made, there are three possible decision categories, namely, a "right decision", a "wrong decision" and "no decision". Most people think there are only two; you're either right or you're wrong. As we normally do not know which is the right or wrong decision, the optimal decision is in fact "no decision" as this defers the commitment until we have more information to make a better informed decision.

However, if we observe the behaviour of most people, we notice that an aversion to uncertainty means people make decisions early. Real Options address this aversion to uncertainty by defining the exact date or conditions to be met before the decision should be made. Instead of saying "not yet", the Real Option approach says "Make the decision when This gives people certainty over when the decision is made and as a result they are more comfortable with delaying the decision.

Delaying commitments gives decision makers more flexibility as they continue to have options. Real Options feels unnatural to begin with. Like leaning down the hill when skiing, or leaning back when you jump from a height on horseback.

"Real Options" Underlie Agile Practices

A few people adopt them naturally. Others need a coach, time and practice to get it. Perhaps like Agile? Perhaps the "unnatural" feel of this uncertainty one of the reasons that some people are so opposed to Agile. Rather than decisions, Real Options is really about commitments.

Quite often people make a decision which becomes an emotional commitment to an idea. They do not realise that they can change their minds. Is agreeing to go to out with a friend an option or a commitment? Most will say a commitment because they have an agreement with their friend, while in reality it is an option. If something happens that provides you a higher value like your dream partner asks you to go backstage at a U2 concert with themyou'll call your friend to reschedule.

An agreement is an option. Financial options have a contractually defined expiry date date on which they end, or expire. The expiry date of Real Options is conditional rather than contractual. The most powerful aspect of Real Options is the method of real options is addition to push back the expiry date of an option, thus giving more time for an optimal solution to be discovered. There is value in paying to defer a commitment. Examples in business These practices are already in use.

As said before, this is nothing new.

Three well known companies are already using this successfully: Toyota, Microsoft and Google. Famously, Toyota waits until a customer buys a car before they start to build it. How's that for deferring commitment?

Microsoft's relationship with Real Options is well known, like the famous trade show where the Microsoft stand "looked like a bazaar". While other companies were betting their company on a single product or strategy, Microsoft was hedging its position so that it could still win the office automation battle even if it lost on the operating system front.

Microsoft is the ultimate master of the wait, and wait, and wait, and see strategy. Consider the Internet Explorer episode where Microsoft waited until the internet had emerged as a technology before moving in.

A question we would love to have answered is: "How many programming teams and solutions did Microsoft consider when faced with this crisis? We suspect the answer is fairly obvious. Google is one of the first Informationalist [7] companies. Rather than enter into conflict with its customers, it cooperates with them. No random banner ads, but rather adverts for products and services that you might actually be interested in.

The Future of Agile It is often too easy to destroy someone else's options. As a result, Real Options works most effectively if participants cooperate with each other.

This goes against common practice of hiding our intent. However, we can learn from Google's approach.

After all, how can I help you if I do not know what you want to achieve Perhaps this should be starting point of Agile management practices.

Method of real options is addition need to learn how to listen so that we can help other people achieve their goals. Leaders must provide and create options to for people they work with instead of making decisions for them.

Real Options is a set of principles that validates certain practices, as shown above, and can be used to generate new practices. Currently agile needs to develop Leadership and Management practices beyond project management that support the agile mindset, to move out of the IT department and into the rest of the corporation.

To give a few examples of how this would work, let's look at decision processes and resource management. Decision process The optimal decision process is as follows: For each decision, identify the options available. Identify the last point at which a decision can be made. This is calculated by working out the deadline for the implementation of an option, and then working back to the decision point i.

The first decision is made when the first option expires.
