INTRODUCTION

The use of organized methodologies for the development of systems and software have been around for 35 years ("PRIDE" was the first in 1971). Today, there are dozens, if not hundreds, of methodologies available for use. Many are simply a variation on the traditional theme of: feasibility study, external design, internal design, program, test, install, review. Others take an iterative approach to development. Regardless of what methodology you elect to use, whether "PRIDE" or Brand X, there are some serious implementation considerations to ponder and it would be foolish not to look before you leap into one.

First, recognize you will spend more time and money implementing a methodology than you will on its purchase. This is because methodologies radically affect the corporate culture, at least in the Information Technology (IT) department. It means breaking old work habits and introducing new ones. It also represents standardization which developers often resist. Methodologies represents uniformity in development practices and deliverables with the intent of turning a heterogeneous development environment into one that is homogeneous. By doing so, methodologies seek to produce consistent and predictable results. They also greatly facilitate teamwork as opposed to rugged individualism. As such, their impact on human behavior should not be underestimated.

SELECTION

Not all methodologies are created equally. Having been involved in this industry for over 30 years, we have had the opportunity to see many different interpretations of the methodology concept. Some are rather simple, others are overtly complex (which we like to refer to as "the dance of the fairies"). When studying any methodology, consideration should be given to the following areas:

* Conceptual Foundation - defining the intent of the product and the rationale for construction of the methodology. First, what is it intended to produce? Total systems or just the software portions? What about the data base? Is this a universally applicable approach or tailored for a specific type of application, e.g., SOA, real-time, etc. This will help define the scope of the methodology and who it is intended to use it. Next, study the underlying concepts and philosophies from which the methodology is based. For example, "PRIDE" establishes an analogy between engineering/manufacturing concepts to the development of systems. This may be fine for those people who understand such concepts, but difficult for others to assimilate. Regardless, the concepts and philosophies must be understood and agreed upon. Further, the terminology used in the methodology must also be well defined and consistently applied throughout it, thereby providing a uniform vocabulary for developers (and end-users) to communicate. Ideally, a glossary of terms is provided with the methodology.

* Methodology Structure and Navigation - defining the standard work breakdown structure (WBS) such as phases, activities, and tasks, along with their dependencies (comes from/goes to). In terms of the WBS, consider the level of detail provided and the rationale for the various work steps. For example, each should be designed to produce a tangible result in order to substantiate completeness. If it doesn't, it may very well be a waste of time. Also, consideration should be given to what work steps must be performed sequentially and which can be performed in parallel. This has Project Management implications.

This can take many forms, such as reports, program code, data base structures, test data, etc. For each deliverable, particularly reports, there should be defined acceptance criteria which provides the means to analyze it for completeness.

The methodology must clearly define Who is to perform What, When, Where, Why and How (5W+H) thereby delineating the responsibilities for executing the various parts of the methodology. Assuming this is understood and agreed upon, the next step is to consider how the methodology will impact your organization. Will it be a radical departure from the current way your company operates or will it be relatively easy to assimilate in your organization? The greater the change, the greater your implementation costs will be. Then again, maybe your organization needs a radical shakeup.

STRATEGIES

Because a methodology plays a dramatic role in the corporate culture, it is not installed in the same manner as computer hardware or software. We have seen many approaches to the implementation of methodologies over the years; some successful, some disastrous. The disastrous implementations are those where a "Dictator" approach is taken and the methodology is jammed down everyone's throat. This will only work as long as the dictator remains in power and is typically abandoned shortly thereafter. The more successful implementations have been those where the responsibility for the methodology is shouldered by several key people in the organization, thereby giving the appearance that the methodology is the will of the company and not just one individual.

STEP 1 - ESTABLISH A PROJECT

The first step in installing a methodology is to establish a project for this purpose. This can be done using a Project Management system (either manually implemented or computer assisted) which materially assists in keeping the project on schedule and within costs.

Key to the startup of the project is the appointment of a Methodology Coordinator who will act as the Project Manager for the implementation of the product. Considerable thought should go into the selection of this person. The Coordinator should be respected by the development staff as well as management; should work well with people, but more importantly, must be results oriented.

STEP 2 - ESTABLISH SUPPORT TEAM

A Support Team is assembled who will be assigned tasks in the project. One of the principal reasons for forming a Support Team is to share the responsibility for implementing the methodology throughout the company. Again, this conveys the image that the methodology is the will of the company, not just a single person.

Selecting members for the Support Team is critical. During the implementation process, they will have high visibility and will become the in-house experts in the use of the methodology. As such, the people selected must be able to speak with authority and command respect. Those typically involved in the implementation of a methodology include:
