Trying to integrate different enterprise software packages can cause some people to start detecting conspiracies.

Todd Park is vice president of information technology at W&W/AFCO Steel, a steel manufacturer based in Oklahoma City. His company has three main enterprise software packages, and enterprise resource planning (ERP) system integration is no fun. Park explained that his company has often tried to set standards for importing data from one application to another, but then it will all just break.

Why? According to Park: bug fixes, software upgrades, and small data changes among other things.

"Suddenly there's an extra space after a comma and all your fields are out of alignment," he said. "It's just a continuous pain in the rear."

So how is Park a conspiracist? Well, conspiracist might be a strong word, but he has suspicions. He thinks software companies update their products often without really caring about quality or backward compatibility. Then when their customers have issues with ERP system integration, the vendor can justify the large maintenance costs they charge to fix it all.

"They're all the same," he said. "They have to continue to justify maintenance costs and keep that number up."

ERP system integration can be a major headache for companies like Park's, and it's a major improvement goal for them moving forward. According to Panorama Consulting Solutions' 2013 ERP Report, one of the top reasons for implementing ERP was to "better integrate systems across multiple locations." That reason was third highest behind improving business performance and replacing a legacy ERP system, both of which may be rooted in integration issues as well. Furthermore, the top benefit realized by implementing ERP, according to the survey of 172 respondents, was "availability of information." That speaks to Park's issues of data validation.

Have an ERP system integration philosophy

Patricia Dues doesn't think of ERP as an application. For Dues, the deputy chief information officer for the City of Las Vegas, ERP is a philosophy.

According to her, vendors have an ERP philosophy, and so end users should as well. Some vendors focus on excelling in one small niche of the ERP market. For example, one of the vendors that W&W/AFCO Steel uses is Sage Construction and Real Estate, a financial software package previously called Timberline that services the construction and real estate industries. That is a very specific niche.

On the other hand, huge ERP vendors such as Oracle and SAP want to be everything ERP for everyone. SAP has ERP software packages for financials, human capital management and operations -- and those are just some of the broad categories that have sub-packages beneath them.

Each philosophy has its benefits and its drawbacks. Going with a product like Sage's means you're getting software that has been designed for a specific task in your specific vertical industry. The big ERP players have worked their way into vertical industries through development and acquisitions, but may not be at the same level as a best-of-breed product that has focused on its niche for years. The drawback is that if you have several different niche applications, your IT staff may spend more time on ERP system integration, developing workarounds to get the software products to share data with one another.

Going with a big ERP product means you'll have one ERP vendor to deal with when there are problems, and hopefully ERP system integration will be easier because it is theoretically all one big application. However, that is not always the case. Oracle, for example, has built its large application portfolio through several acquisitions over the years, then placing them under the Oracle umbrella. But the name on the front doesn't necessarily mean the technology in the back will work well together. That is why Oracle has spent a lot of time and money developing its Fusion Middleware platform, which ties all the disparate Oracle applications together.

Dues said that working for a government agency such as the City of Las Vegas means that "you can't have just one vendor. It's just not possible."

"But we try to buy from one vendor as much as possible, because integration is easier," she added. "That is how our ERP philosophy has been established."

Dealing with disparate applications is almost inevitable, and Dues gave an example. When a criminal is arrested in Las Vegas, he gets booked into the court system using software from Motorola called OffenderTrak. Dues said it would be nice to have an ERP vendor that could handle all aspects of public safety, "but there isn't one we've found that met all our needs."

OffenderTrak creates an initial record on a criminal, which is processed into a customized written application that the court uses. That record tracks the criminal through the court system. Meanwhile, the City of Las Vegas has a neighborhood services division that has information on how safe certain neighborhoods are. It needs to access those criminal records -- built on a customized application, which imported data from Motorola OffenderTrak -- to see where certain crimes happen and where certain criminals live.

"All these things have to come together, mostly for reporting," Dues said.

Get ready for cloud ERP integration

Coming up on the radar, if it isn't there already, are cloud applications that must integrate into an ERP system. According to Floyd Teter, executive vice president of strategy and products and EiS Technologies Inc. and a well-known Oracle applications expert, it's a problem.

Teter said that Oracle has GoldenGate for replication and Oracle Data Integrator for big data migrations, but both of those are hard to do when a cloud vendor -- not just Oracle but any cloud vendor -- won't allow you to have access to your database on the cloud. The cloud vendor may offer you a Software-as-a-Service model, providing you with applications and a browser but no back-end control. Then they say they'll push data out to you on a periodic basis.

"Well, once a quarter, once a month, that's not going to cut it," Teter said. "[We're] talking about multiple times a day."

Teter added that Web services such as representational state transfer and Simple Object Access Protocol are not designed to move a lot of data or to provide heavy volume with small chunks of data.

"So performance slows down," Teter said. "That's the biggest issue. I think as we see the cloud mature, we'll see some resolution to that, but right now I think that is one of the big hurdles."
