Change in organizations is one of the issues that have been studied from different perspectives, and by different disciplines, as an important aspect in management. Previously we have paid attention and reviewed the physiological aspects of changes, now we will focus on the managerial aspects of changes within organizations.

Where does maintenance generate value for the company? How can we measure and compare different maintenance departments’ performance? How can we measure the consequences of a poor maintenance management?

In this process we deal with necessary actions to preserve the network operating conditions. A network is like an operating machine, which inherently degrades progressively (due to the passage of time, to manipulations, to different external actors, etc.) and that requires certain efforts to avoid such degradation.

The “manage strategy” process coordinates and integrates maintenance management activities in order to achieve the department objectives [20, 32]. This process also analyzes that these objectives are aligned with company’s goals (see Fig. 6.1).

In maintenance management, we must take many times decisions under high levels of uncertainty and that is not normally an easy task [19]. In this section we first introduce some basic and important concepts related to decision-making in management science and then we somehow discuss about the application of those concepts to the management of maint...

The process “To Analyse Maintenance” provides technical support to maintenance and requires the necessary expertise for the resolution of network and services problems. The process allows maintenance management continuous improvement process by using prognosis, predictive and perfective maintenance.

The expression “public utility” or “utility”, first used in 1903, is defined by Merriam-Webster’s Collegiate® Dictionary, Eleventh Edition (http://www.merriam-webster.com), as “a business organization performing a public service and subject to special governmental regulation”. In the same manner, the Encyclopædia Britannica (http://www.britannica.c...
