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

Steps
Identify Stakeholders

Identify the decision-makers, customers, potential users, partners, domain experts, industry analysts and other interested parties (see Role: 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 Artifact: Vision.

Gain agreement on the problem to solve
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 Guideline: Requirements Gathering Techniques. Formulate the problem statement, and then fill in the corresponding section from  Template: 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 Guideline: Requirements Gathering Techniques. Each one is applicable in a particular situation or type of stakeholders.

If you can meet stakeholders in person, then you can conduct an interview or a brainstorming session. If you don't have direct access to stakeholders, or if there are many individuals in many locations, then you can use a questionnaire. If constructed carefully and conducted online, questionnaires can also more easily provide statistical data that reflects what stakeholders really need.

For more information, see Task: 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.

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.
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 Guideline: Effective Requirement Reviews for more information.
