Real options limit
Thinking in terms of real options
Jun 08, 16 min read by Chris Matts 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. By avoiding early how to earn adena faster, you gain flexibility in the choices you have later. A more formal definition will follow.

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.
Dynamically control the availability of application features to your users. Start Free Trial. Behaviour Driven Development and Test Driven Development provide many options, especially "the real options limit 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 real options limit finished, instead real options limit 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.
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. Real options limit 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 . 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 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. 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.
Она бросилась к лестнице и начала подниматься к кабинету Стратмора. За ее спиной «ТРАНСТЕКСТ» издал предсмертный оглушающий стон. Когда распался последний силиконовый чип, громадная раскаленная лава вырвалась наружу, пробив верхнюю крышку и выбросив на двадцать метров вверх тучу керамических осколков, и в то же мгновение насыщенный кислородом воздух шифровалки втянуло в образовавшийся вакуум. Сьюзан едва успела взбежать на верхнюю площадку лестницы и вцепиться в перила, когда ее ударил мощный порыв горячего ветра. Повернувшись, она увидела заместителя оперативного директора АНБ; он стоял возле «ТРАНСТЕКСТА», не сводя с нее глаз.
Whereas a PhD or Masters in financial mathematics is required to derive Black Scholes or prove the statement we just made, no 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.
Options expire. Never commit early unless you know why.
So What are Real Options?
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?
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.
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" .
However, whereas Preston's statement was an opinion based 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.
Viewing Agile through Real Options
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 Investment platform 5 feels unnatural to begin with.
Like leaning down the hill when skiing, or leaning back when you jump from a height on horseback.
A few people adopt real options limit 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 How to make money fast and a lot 2020. Rather than decisions, Real Options is really about commitments.
Why real options are important
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?
