Operations and Maintenance

Before you begin to receive requests for changes, it should be determined how each will be managed. This is accomplished by defining the Configurable Items (CIs) for each application. These are any item that can be modified within the system. They can be as detailed as listing each field that can be configured, each piece of a report, or each part of a server. They could also be broader, such as a new clinical document or an update to a current clinical document, without listing each possible item. The level of detail should be enough to identify how each should be managed. The CIs should be documented in a way that allows for searching and modifying as needed. This could be done in a spreadsheet, a simple database, or in a CM-specific application. A baseline should also be documented once the system is live. The baseline is a snapshot of a system’s components (such as hardware, operating system, code or configuration, and associated data) to which changes can be applied. The baseline can only be changed through the formal CM process, and a new baseline should be created once a change is made. While this is best practices, most organizations create a new baseline after each release or at some regular interval.
Evaluating Reliability Programs for Nuclear Power Plants

In addition to auditing and evaluating the reliability aspects of the program, the effectiveness of the configuration management function must also be assessed. Configuration management is a discipline in which technical and administrative direction and surveillance are applied to identify and document the functional and physical characteristics of a hardware or software item that satisfies an end use function, to control changes to those characteristics and to record and report implementation status on approved changes. It is used to establish and maintain a formal set of procedures by which a uniform system of change identification, coordination, approval and status accounting is accomplished. The procedures are planned early during development and implemented later during acquisition when the system is first placed under configuration management control. Controls are defined for formal documentation (specification, plans, drawings, manuals, etc.) related to facilities, systems and equipment items and computer programs. The implementation of a well-planned properly executed configuration management function is essential to the performance of many of the elements of a reliability program (e.g. assessment, failure analysis and data recording) as well as to the effectiveness of the overall program.
Systems Engineering as a Project Enabler
Published in Lory Mitchell Wingate, Systems Engineering for Projects, 2018
Configuration management is a technique that a systems engineer will use to control and manage change within the technical areas of responsibility. It is a critical methodology that is implemented so that the form and function of the system and all of the products, subsystems, component, or parts are known at any given time. It is an important governance activity. As important as this is to the systems engineer, it is equally as important for the project manager to understand throughout the project life cycle the as-allocated, as-designed, as-built, and as-maintained configurations to assure that the anticipated project outcomes are on track.

The ULWC is more customizable than other categories of MWCs. Customization provides for individualized configuration and adjustability. Both characteristics are essential for people who are first beginning to propel a MWC, those who have a lifetime of experience to know exactly what works for them, and those who have a condition that changes over time. While studies suggest that durability is comparable across models, client feedback and opinions are important factors in determining overall functional outcomes and client satisfaction. The ULWC provides the best options for maximizing functional potential, preventing secondary complications related to MWC use, and maintaining function over time. The most frequent considerations are overall weight, configurability, and compatibility with seating and postural supports.
