Tarea: Define Vision
Define the vision for the future system. Describe the problem and features based on Stakeholder requests.
Disciplinas: Requirements
Objetivo
The solution is proposed for a problem that everybody agrees on. Stakeholders collaborate with the development team to express and document their problems, needs, and potential features for the system to be, so the project team can better understand what has to be done.

Identify Stakeholders

Identify the decision-makers, customers, potential users, partners, domain experts, industry analysts and other interested parties (see Rol: Stakeholder). Develop profiles of potential (or actual) users of the system that map to the roles of human actors of the system that you are developing. Document the initial information on key users and their environment in the Artefacto: Vision.

Gain agreement on the problem to be solved
Avoid rushing into defining the solution. First, gain agreement on the definition of the problem by asking the stakeholders what they see as the problem. Then search for root causes, or the “problem behind the problem.” Use techniques like the ones described in Directriz: Requirements Gathering Techniques. Formulate the problem statement, and then fill in the corresponding section from Plantilla: Vision. The purpose of this is to help you distinguish solutions and answers from problems and questions.

Capture a common vocabulary
Every project has its own specialized terminology that everyone on the team must understand well to communicate effectively with stakeholders. Work with stakeholders to create a glossary that defines acronyms, abbreviations, and relevant business and technical terms. Work with stakeholder to continually expand and refine the glossary throughout the project life cycle.
Gather stakeholder requests

Use the most appropriate method to gather information, such as the ones in Directriz: Requirements Gathering Techniques. Each one is applicable in a particular situation or to a certain type of stakeholder.

If you can meet stakeholders in person, then you can conduct an interview or a brainstorming session. This face to face collaboration is extremely valuable and reduces the chances of the project team misunderstanding the needs of the stakeholders.

Some requirements may already be documented in an existing Work Item List. This can often be used as a solid starting position from which a full set of requirements can be created.

Any requirements gathered during this step should be captured in the Work Item List.

For more information, see Tarea: Find and Outline Requirements.

Define the system boundaries

Find and define the line that divides the solution and the real world that surrounds the solution. Identify interfaces, as well as input and output information exchanged with users, machines, or systems.

A Use Case Model is one technique that can prove useful in defining the system boundaries.

For more information, see Tarea: Find and Outline Requirements.

Identify constraints on the system

Consider the various sources of constraints that can impact the design or the project itself:

  • Political
  • Economic (budget, licensing)
  • Environmental (regulatory constraints, legal, standards)
  • Technical (platforms, technology)
  • Feasibility (schedule, resources allocation, outsourcing)
  • System (solutions compatibility, support of operating systems and environments).
Define features of the system

Work with stakeholders to capture a list of features that stakeholders want in the system, briefly describing them and giving attributes to help define their general status and priority in the project.

Update the Artefacto: Work Items List to capture the features identified and their attributes.

Achieve concurrence
Conduct a review of the project vision with relevant Stakeholders and the development team to ensure agreement, assess quality, and identify required changes. See Directriz: Effective Requirement Reviews for more information.
