VBM - Vision Based Methodology

VBM is a waterfall approach which is still used by developers who focus on mainframe and mid-range projects - yes there are still many of those developers working - we have continued to keep this on our website as a reference resource. Take a walk through the sub maps if you simply want to refresh your memory about the the basic principles of software development.

Activity 1. Selling the Idea

A project idea doesn't go anywhere unless it actually becomes a project. This VBM activity examines various approaches to building a base of support for a proposed effort, and then actually winning the necessary approval and financing.

Activity 2. Creating the Plan

Before the project effort gets underway, the plan should be completely thought through. As a part of this, staffing requirements should be determined, high level goals and calendar milestones should be charted, and development activities should be outlined. This VBM activity focuses on the planning process and its use throughout the life of the project.

Activity 3. Building the Team

Determining who will be on the team is one thing, but keeping the team together and performing at its maximum potential is another. This VBM activity explores a multitude of team building and project management approaches, and their effective use throughout the systems development effort.

Activity 4. Uncovering the Requirements

A critical step in the system development/enhancement process is the definition of the project requirements in business client terminology. This VBM activity examines an assortment of requirements gathering techniques, with a strong emphasis on the utilization of a facilitated session approach for collection and confirmation of the bulk of the major system functional definition.

Activity 5. Modeling the Business

As the business requirements are being collected, a "picture" of the important business information and the related processes begins to emerge. Capturing this evolving image in a manner which serves as a communication tool for both the technical as well as the business project participants, is the centerpiece of this VBM activity. An overview is provided of many of today's current major modeling techniques.

Activity 6. Conceptualizing the System

Turning business requirements into business solutions is the act of defining how the requirements will be satisfied, which technological platforms will be utilized, and what the system will look like. This VBM activity reviews the transformation of logical requirements into physical components. In addition, the discussion highlights current software development standards and technological trends.

Activity 7. Creating the Vision

Designing the business components of the system, and then putting this vision into a form which can be reviewed by the business clients, is the focus of this VBM activity. Strong emphasis is placed on the use of an iterative prototyping approach for the design of the various screen, form, window, and report layouts.

Activity 8. Specifying the Vision

Each individual system component should be carefully defined, and its internal workings should be clearly documented, in the form of a program specification. This VBM activity outlines various specification approaches which can be employed to capture the functional details based on the contemplated construction methodology. Special attention is paid to traditional procedural programming, automated code generation, and object-oriented programming.

Activity 9. Constructing the System

No matter which methodological route is taken, at some point someone will have to either generate the program logic or bear down and write the actual program code. This VBM activity takes an extensive look at all of the considerations and techniques which surround this activity. A sharp focus is aimed at the key process of turning specifications into fully integrated and tested programs.

Activity 10. Reselling the Idea

Once the system has been completed, it must be introduced into the business environment. This VBM activity examines the issues and approaches involved with managing the organizational change process, guiding the system through acceptance testing, and equipping the business clients with the training and documentation they will require to gain their independence from the system builders!
