While process consultation is central to most OD strategies, it is also true that OD has become much more sophisticated in recent years and includes technological, structural, and human systems changes which have been integrated to transform the organizational system. Organizations are "whole systems", large systems made-up of "systems within systems". The supervisory system, for example, is affected by the work technology itself. Reward systems affect the individual and team motivational system. The managerial goal system will be directly tied to the performance management system. These systemic integrations are dynamically inter-related, but not always in predictable ways. The consultant will normally use a number of these interventions to resolve client issues which emerge from sophisticated diagnostics. (As the text notes, another way to break these interventions down analytically is to categorize them as individual, team, intergroup, and total organizational system interventions.) In large scales OD interventions, many consultants may be working with the organization at any one time. This will call for the use of interconnected intervention links and project planning strategies so that all of these various change efforts occur at the right time, with the right people, and in the right way. This is known as stream analysis. To the extent that OD consultants continue to utilize overly simplistic behavioral models, they are less likely to seriously impact major causes of outcomes such as low productivity, dissatisfaction with jobs, and the ability to deliver products and services, rapidly, to the customer.
