Part One defines EAM and CMMS.
Part Two discusses integration concerns.
Part Three and Four began the
analysis of two major vendors.
Introduction
Enterprise asset management (EAM) software and
computerized maintenance management systems (CMMS) continue to
grab headlines as a realistic way to reduce expenses and increase
revenues. For one, maintaining an adequate level of repair and
service parts inventory based on forecasted equipment usage can
prevent already limited funds from being over-allocated just to
achieve a false sense of security. Also, an effective preventive
maintenance program can improve equipment utilization and
availability, enabling production schedules to be achieved
especially when an exorbitantly expensive equipment replacement is a
no-option during depressed economic times. Extending into the
customer base, this applies as much to standards of service as it
does to product quality.
What attracts companies to this class of software is that the
savings are tangible and real—you know, the kind that you can take
to the bank. Consequently, the advantage that EAM/CMMS has over
other types of enterprise applications is that its return on
investment (ROI) is often reasonably quickly achieved and
easily quantified. Namely, it is a relatively straightforward
exercise to demonstrate the bottom line value provided by optimized
utilization that results from optimally maintained production
equipment and the facility where it is housed.
This article looks at where CMMS ends and EAM
takes over, with particular emphasis on features and functionality
of EAM software. If you are unsure of the capabilities of CMMS and
need a quick refresher course, read the TEC article entitled,
CMMS: A Tutorial.
Offerings from software vendors, IFS AB (XSSE: IFS)
and Intentia (XSSE: INT B), two fellow Swedish
providers of enterprise business applications for midsize and large
enterprises, will be used to help illustrate some of the advanced
features of EAM.
The remainder of this article compares CMMS and EAM software and
explores, in more detail, two key differentiators: integration
concerns and reliability-centered maintenance (RCM). The
article ends with a background on Intentia and IFS, and with a
general discussion about enterprise resource planning (ERP) vendors’
foray into the EAM/CMMS arena.
Comparing
CMMS and EAM
Many regard EAM as CMMS on steroids, which is an oversimplification
and does not paint the true picture. Typically, CMMS deals strictly
within the confines of the work order and preventive maintenance
activity. Specific functions include
-
Scheduling preventive maintenance based on triggers (such as hours
of operation) or timed events (for example, every three months)
-
Ensuring probability-based availability repair and spare parts
-
Serial number tracking and tracing
-
Suggesting and originating the purchase of needed repair parts
-
Warranty tracking
-
Ensuring availability of manpower resources with required skills
and training
-
Maintaining an asset registry and repair parts database (i.e.
nomenclature, hierarchy structure, where used, support
descriptions, etc.)
-
Tracking costs of maintaining individual pieces of equipment
-
Differentiation and appropriate management of fixed, mobile, and
continuous assets
-
Recording unexpected events for further analysis
-
Statistical
analysis of equipment performance and reliability, and providing a
variety of reports from static and dynamic sources (i.e. equipment
utilization, equipment downtime, MTBF—equipment mean time between
failure, MTTR—equipment mean time to repair, etc.)
EAM software encompasses these functions and, in most cases, extends
their capabilities but EAM software offers many features that can
provide additional capabilities, value added functionality, and
savings to your company. As seen above, a CMMS solution usually
includes purchasing and procurement, inventory management, as well
as equipment, parts, and asset tracking. However, CMMS applications
typically do not have financial and accounting (other than mere cost
recording) or human resource (HR) management capabilities
(other than basic staffing needs recognition) and are typically
purchased to integrate with the applications that support financial
and HR management more deeply. These back-office applications are
also typically designed to run at and for a single plant.
The CMMS functionality is thus typically extended to EAM by the
addition of financial management modules, and more advanced HR
management to cater for roster creation and management, and for
recording and monitoring necessary skills. Technically, the EAM
applications are also designed to scale to larger numbers of users
and facilitate running at multiple sites from a single central
database, thereby catering better to entire enterprises, rather than
departmental or individual plant needs.
To
that end, both IFS and Intentia’s EAM offerings can schedule
preventive maintenance and manage these activities as well as
unplanned maintenance. However, these products seamlessly extract
and update data from Microsoft Project workplans, a
popular project management tool. Additionally, Intentia’s EAM is
integrated with Movex Advanced Production Planner (APP),
its production optimization tool. As a result, production orders and
maintenance work orders for the same production line can be planned
simultaneously, thus providing the possibility of scheduling
maintenance work into available production windows. Moreover, the
product is designed to plan production work around any maintenance
issues, so that production is optimized.
EAM Offers
More
EAM software offers a more robust methodology for documenting
equipment and their parts to include warranties, schematics, and
computer aided design (CAD) drawings. Through IFS’s
Plant Design set of modules, once data is entered into the
common database, it immediately becomes available to the other IFS
modules. As a result, information can be recycled, remain
consistent, and updated, and never has to be entered twice. Plant
Design also provides designers with a drawing tool for process and
instrumentation design. Predefined forms and convenient lookup
functionality are further examples of features that benefit all
design disciplines.
EAM software provides better and more conclusive analysis of the
maintenance, repair, and, overhaul (MRO) alternatives. The
Intentia Diagnostics module, which is used to provide RCM
functionality, calculates the cost of failure based on the downtime
costs multiplied by the downtime plus any additional repair. It also
provides an additional analysis, namely cost prevention, which is
based on the cost of the maintenance service, including labor and
parts, over the same period of time as the mean time between
failures (MTBF).
What does it mean to your company to have the resource available,
based on historical trends and a preventive maintenance schedule? Or
more simply stated: is it costing the user more to maintain the
resource than the value it is providing? On the other hand, through
an interface with its fixed assets module, IFS provides an
interesting wrinkle to the overhaul alternative. Its EAM offering
will consider undertaking a major overhaul, say of an engine
replacement, if this activity results in a significant extension of
the useful life of the asset to generate sufficient depreciation
expense to warrant the overhaul.
Both of IFS and Intentia’s EAM offerings provide excellent tools by
which to customize access to the software. This customization
includes screen views, database queries, and report layouts.
Personal portals cover the most common functions and features
required by maintenance technicians. The end result is an easier
assimilation and use of the software and can smooth the learning
curve. As will be discussed later in this article, a major
differentiator of EAM software is the reliability-centered
maintenance (RCM) concept, which is supported by both IFS and
Intentia.
