Integration
Concerns
Many of the benefits from enterprise asset management (EAM)
software result from the ability to exchange data from other systems
and subsystems. These interfaces are not trivial in design or
construction. For example, one of the simpler interfaces involves
inventory. Namely, EAM software needs access to inventory to
determine the availability of repair parts, whereas your
manufacturing system needs access to inventory to dispense
ingredients or bills of material (BOM). Typically, EAM
software will have its repository of inventory consisting of repair
parts. On the other hand, a manufacturing ERP system will have its
repository of inventory, which can accommodate ingredients, BOM, and
repair parts. Designers of manufacturing systems are not that
short-sighted to think that every company has computerized
maintenance management systems (CMMS) or EAM software.
Some basic questions include
-
Where is the official inventory maintained?
-
How
do you keep the inventories in sync?
-
What flares will go off when they go out of sync?
-
How do you put them
back in sync?
However, in the software development world, these are difficult
questions to answer and design for; moreover these are just the tip
of the interface iceberg. The table below lists some of the
potential EAM interfaces.

Granted some of these may be overkill, but, even if only half are
needed or desired, the interface issues and construction represent a
major commitment of time and resources, now and in the future. The
good news is that if you can satisfy all of your software needs from
a single source, which can be done through IFS and Intentia, your
interfaces are most likely already resolved for you*. Again, this is
a strong selling point for IFS and Intentia.
However, while most companies recognize the value of EAM software,
many have not even taken the first step. These companies, of
necessity, already have existing systems to control their inventory,
payables, manufacturing, payroll, and other functions and, due to
time and monetary considerations, are not likely to give to them up
for new, fully integrated software. The bottom line? Companies
selecting a new ERP system should include a review of the EAM
functions in each product, particularly in process and asset
intensive industries where good EAM is frequently seen as being
critical to the business. However in most cases, companies will
acquire EAM software but the interfaces to external systems will
have to be constructed.
When providing a stand-alone solution, vendors may oversimplify the
interface issues by suggesting the availability API’s (application
programming interfaces) or software-based integration services.
They may also pressure you into buying more modules than you need.
These statements may have validity. However, in the case of
interfaces, it may be wise to be the “Doubting Thomas as you move to
Missouri, the ‘show me’” state: this is clearly a case where you
must do your homework beforehand and not solely rely on the claims
of the provider. Request references from clients who have actually
created interfaces; determine the time and effort required; check
the cost of any customization to meet your specific needs as a
so-called "standard" interface rarely meets these; and verify that
there are no degradation of performance on either side of the
interface—existing and EAM software.
*In this note offerings from software vendors IFS AB
(XSSE: IFS) and Intentia (XSSE: INT B), two fellow
Swedish providers of enterprise business applications for mid-size
and large enterprises, are used to help illustrate some of the
advanced features of EAM.
What Would
ERP Vendors Do?
Prior to, during, and shortly after the Y2K phenomenon,
enterprise resource planning (ERP) software vendors had plenty
of sales and implementation work. ERP systems are suites that
typically support most business functions inherent within an
enterprise, and because ERP providers may tailor their solutions to
meet the needs of various industries, ERP packages may also vary in
their functional scope and supported modules. Namely, certain
vendors focus on service-based (i.e. people-centric rather than
physical products-centric) industries, others’ solutions are geared
towards retail distributors, while the manufacturing-oriented
vendors support material management, production planning,
scheduling, and execution. Many vendors tackle multiple areas
though, both above-mentioned and beyond.
Still, given plant maintenance is a core business component of many
manufacturing enterprises, one would expect ERP products to at least
feature native CMMS functionality. Thus, it might not be too
dazzling a fact that IFS and Intentia (as well as SAP,
Oracle, Ramco Systems, and former
J.D. Edwards now PeopleSoft) have
been offering maintenance modules for years. Well, not quite, given
most ERP vendors have deliberately stayed away from addressing the
needs of the maintenance departments, which had created the
opportunity for CMMS/EAM specialists.
Nonetheless, ERP vendors have lately been scrambling to provide
maintenance and asset management for various reasons, such as the
bolstered competitiveness through an enlarged functional footprint
and existing customers’ or prospects’ inquiries and demands.
Furthermore, now that they are chumming for additional sales, these
entrant vendors are facing the same interface issues when attempting
to incorporate an EAM solution with existing software functionality.
Consequently, it is not surprising that typical ERP software has not
traditionally excelled in the EAM or CMMS arena. Of late, the
landscape is starting to change with more ERP vendors, either
reluctantly or not, beginning to challenge the standalone EAM
solutions. At least, major vendors of EAM/CMMS software face strong
head-to-head competition from several suppliers of ERP software that
natively offer maintenance modules, bundled into the larger ERP or
supply chain management (SCM) context.
The contest here is classic, and déjà vu, in
SCM and CRM arenas —the user will have to chose between standalone
best-of-breed (BOB) software and a fully integrated module
that often lacks some of the “bells and whistles” featured in a BOB
offering (see
Best of Breed Versus Fully Integrated
Software: The Pro’s and Con’s)
. Also, since pure play EAM vendors do not rely on existing ERP
modules to support certain maintenance operations, their more
complete functionality may provide a better fit with how certain
maintenance departments operate than with internally developed EAM
solutions by ERP vendors. Also, as the EAM software has been
evolving into a mature, slower-growth market, many incumbent vendors
are responding to this by offering high-margin, value-added
services, such as helping to install, integrate, maintain, and even
host the software, which has already been purchased by many of the
major customers in asset-intensive industrial sectors.
Given slower projected growth and competition from ERP vendors,
major vendors of stand-alone EAM or CMMS packages such as
Datastream Systems, Indus, Avexus,
Mincom, MRO Software, and
PSDI have been reengineering their product suites around
the Web and enhancing their global capabilities. Additionally, they
have been adding capabilities such as e-commerce, fleet management,
facility and property management (stretching beyond production
facilities to offshore drilling platforms, fleet, IT equipment like
local- and wide-area networks, computers, mobile devices, and even
point-of-sale terminals), often by partnering with specialized
players to be more competitive in various niches. They are targeting
large existing customers in process industries (petrochemical and
oil refiners as well as mining and metals processing) and hybrid
sectors as prime candidates for their value-added services. However,
the major challenge of these vendors is to win increased acceptance
among discrete manufacturers that have not readily purchased this
increasingly proven productivity tool in the past, and which has
been ERP vendors’ more fertile area.
Reliability-Centered Maintenance
Going back to the EAM/CMMS comparison, reliability-centered
maintenance (RCM) is the critical differentiator between a CMMS
and EAM software. RCM is a process for defining a cost-effective
schedule for each asset necessary to maintain reliable performance.
In order to establish this schedule, reasonable expectations of
performance, limitations, and priorities must be established for the
physical asset. Instead of focusing on preventing an asset from
failing, RCM concentrates on ensuring on its continued reliability.
It shifts the maintenance paradigm from one of prevention to one of
prediction so that appropriate action can be taken early on.
Furthermore, creating a RCM environment is not a one-time process.
Rather, it is a continuous, evolving, and ever-improving process of
analysis.
Both IFS and Intentia’s EAM offering provide the bio-feedback
process. Through its cost and statistical data, Intentia’s EAM
analyzes failure patterns, determines the consequences of these
failures, suggests alternative maintenance programs, analyzes the
cost of maintenance programs versus the cost of failure, and
activates the selected program upon approval. This multi-step
analysis can be repeated at the discretion of the user or when
conditions, namely repeated failures, warrant it.
Similarly through its equipment metering, monitoring and performance
modules, IFS’ RCM functionality is enabled through data collection
from automated systems and criticality analyses. IFS’ approach is
that, through continuous investigation and examination, the right
jobs are done at the right time, ensuring proactive asset
management, minimal waste of time, and ongoing asset reliability.
