Precursor experiments[ edit ] Before the introduction of this theory by Wilson and Kelling, Philip Zimbardoa Stanford psychologist, arranged an experiment testing the broken-window theory in Zimbardo arranged for an automobile with no license plates and the hood up to be parked idle in a Bronx neighbourhood and a second automobile in the same condition to be set up in Palo Alto, California. The car in the Bronx was attacked within minutes of its abandonment.
Stakeholders Actively Participate When you are requirements modeling the critical practice is Active Stakeholder Participation.
There are Essays on goal setting theory issues that need to be addressed to enable this practice - availability of project stakeholders to provide requirements and their and your willingness to actively model together.
That must have come from some form of project stakeholder, so they clearly exist. Yes, it may be difficult to find these people. Yes, it may be difficult to get them to participate. In Overcoming Common Requirements Challenges I discuss several common problems that development teams often face, including not having full access to project stakeholders.
My philosophy is that if your project stakeholders are unable or unwilling to participate then that is a clear indication that your project does not have the internal support that it needs to succeed, therefore you should either address the problem or cancel your project to minimize your losses.
What does it mean for a project stakeholder to actively participate? Figure 1 presents a high-level view of the requirements process, using the notation for UML activity diagramsindicating the tasks that developers and project stakeholders are involved with.
The dashed line is used to separate the effort into swim lanes that indicate what role is responsible for each process. In this case you see that both project stakeholders and developers are involved with identifying ideas or suggestions, discussing a potential requirement, and then modeling and potentially documenting it.
Project stakeholders are solely responsible for prioritizing requirementsthe system is being built for them therefore they are the ones that should set the priorities. Although prioritization and estimation of requirements is outside the scope of AM, it is however within the scope of the underlying process such as XP or UP that you are applying AM within, it is important to understand that these tasks are critical aspects of your overall requirements engineering effort.
For further reading, see the Agile Requirements Change Management article. A UML activity diagram overviewing the requirements engineering process.
My philosophy is that project stakeholders should be involved with modeling and documenting their requirementsnot only do they provide information but they actively do the work as well.
Yes, this requires some training, mentoring, and coaching by developers but it is possible. I have seen project stakeholders model and document their requirements quite effectively in small start-up firms, large corporations, and government agencies.
Why is this important? Because your project stakeholders are the requirements experts. They are the ones that know what they want and they can be taught how to model and document requirements if you choose to do so. This makes sense from an agile point of view because it distributes the modeling effort to more people.
Adopt Inclusive Models To make it easier for project stakeholders to be actively involved with requirements modeling and documentation, to reduce the barriers to entry in business parlance, you want to follow the practice Use the Simplest Tools.
Many of the requirements artifacts listed in Table 1 below can be modeled using either simple or complex tools - a column is included to list a simple tool for each artifact.
By keeping it simply you encourage participation and thus increase the chances of effective collaboration. An essential user interface prototype.

Of course, the challenge with such models is their impermanence. When your agile team is geographically distributedfinds itself addressing a complex domainor finds itself in a regulatory compliance situation which requires more permanent artifacts, then you will need to consider capturing key information in software-based modeling tools SBMTs as well.
Take a Breadth-First Approach My experience is that it is better to paint a wide swath at firstto try to get a feel for the bigger picture, than it is to narrowly focus on one small aspect of your system.
By taking a breadth-first approach you quickly gain an overall understanding of your system and can still dive into the details when appropriate. Many organizations prefer a " big modeling up front BMUF " approach to modeling where you invest significant time gathering and documenting requirements early in the project, review the requirements, accept and then baseline them before implementation commences.
This sounds like a great idea, in theory, but the reality is that this approach is spectacularly ineffective.
A study performed by M. Thomas in the U.
Why does this happen? Things change between the time the requirements are defined and when the software is actually delivered. The point is that you can do a little bit of initial, high-level requirements envisioning up front early in the project to understand the overall scope of your system without having to invest in mounds of documentation.Figure r-bridal.comd class type architecture.
I originally used the term "class type" because I first started with this approach using object-oriented (OO) technology, although since then have used it for component-based architectures, service oriented architectures (SOAs), and combinations thereof.
