Ask Slashdot: When Is It Better To Modify the ERP vs. Interfacing It?

New submitter yeshuawatso writes I work for one of the largest HVAC manufacturers in the world. We've currently spent millions of dollars investing in an ERP system from Oracle (via a third-party implementor and distributor) that handles most of our global operations, but it's been a great ordeal getting the thing to work for us across SBUs and even departments without having to constantly go back to the third-party, whom have their hands out asking for more money. What we've also discovered is that the ERP system is being used for inputting and retrieving data but not for managing the data. Managing the data is being handled by systems of spreadsheets and access databases wrought with macros to turn them into functional applications. I'm asking you wise and experienced readers on your take if it's a better idea to continue to hire our third-party to convert these applications into the ERP system or hire internal developers to convert these applications to more scalable and practical applications that interface with the ERP (via API of choice)? We have a ton of spare capacity in data centers that formerly housed mainframes and local servers that now mostly run local Exchange and domain servers. We've consolidated these data centers into our co-location in Atlanta but the old data centers are still running, just empty. We definitely have the space to run commodity servers for an OpenStack, Eucalyptus, or some other private/hybrid cloud solution, but would this be counter productive to the goal of standardizing processes. Our CIO wants to dump everything into the ERP (creating a single point of failure to me) but our accountants are having a tough time chewing the additional costs of re-doing every departmental application. What are your experiences with such implementations?

    I would hire devs to interface with the ERP. Because when you go to upgrade to the next version [of the ERP], you have a modular thing that you can change pieces of rather than having to pay someone to rewrite the entire thing. If you continue to customize the ERP you're using, you'll be locked in to that specific version and all of its security/stability/functionality problems.

      I agree. If you are spending millions of dollars on your ERP, you should probably have in house developers capable of customizing your system (unless you just mean a couple million over a decade or so). You will probably always need some help from consultants, but a good deal of the work could be done by your own staff. This would likely save quite a bit of money. I work as a consultant on various ERP and CRM systems, and all of our long term clients eventually start to bring the work in house because of costs. Our load goes down as they hire more people, but we usually stay available with support contracts for years.

      And the first thing your in house devs should control is the integrations between your ERP and home ground applications. Companies that rely on consultants to handle their integrations become very dependent on those consultants.

      There is nothing wrong with having a large number of integrations. If you have a large system, the belief that you can get all business processes into one ERP system is probably just a dream. But getting a firm handle on all of your integrations is an attainable goal. Then you can make more informed decisions on when and how to move functionality into your ERP software. And you can be more comfortable that you are re-implementing that functionality properly.

      Disclaimer: My day job is re-engineering the integrations for ERP/CRM systems, so take the importance I give to the integrations with a grain of salt.

      EXACTLY THIS!

      For the love of all that is sane, make external interfaces.

      This has the added benefit of providing an easy to find definition of your non ERP standardized business practices.

      If the data belongs in the ERP, it should be managed in the ERP. If it is not, that means your ERP configuration is missing important business workflows and practices. The more the ERP breaks, the less people trust it, and the more they try to do outside of it. Your ERP should not have several feeders of business rules data.

      It is one thing for the external interfaces to have good data, and send good data. It is another to bury all the source data in separate apps. I'm just imaging 100 little spreadsheets and Access databases propagating bad information across each other.

      This is good advice. In-house expertise is always preferable when possible.

      I would not call the ERP a single point of failure though. It means having one version of the truth. If you have one place where the data is kept (and only one place), then the data will be correct - or as correct as the people using it need it to be. If you have it in multiple places, then none of them will be correct. Especially if spreadsheets are among the places where the data is kept and manipulated.

      I would recommend using the ERP database as the master repository for every business application, even if you are using other custom apps to curate the data. That way you can maintain the business rules at the Oracle DB level and ensure data integrity.

      The macro-laden Access databases and spreadsheets are fine for laymen to prototype their business models - but you have to hand it over to real developers to build enterprise class applications using the Oracle DB when it is time to go to production.

      You can sell all of that to the accountants by including a push toward automation of the GL by using the ERP as a subledger. You can save tons of money on accountants and auditors by having every action in the company reliably captured in a database and automatically rolled into the accounting systems. Also, the board reports suddenly become reliable and easy to produce if you have a single version of reality. Bringing all of these little apps up to spec is a no-brainer. Sure, some of the managers who like having local control over their macros will complain about being hamstrung by IT, but it has to be done.

  4. Vendor vs In House by James-NSC · · Score: 5, Insightful
    One of the key problems I've run into, not only in regards to ERP, but in general, is that when you outsource all of your development your future is in the hands of someone who doesn't have your companies best interests as their primary concern. Their primary goal is to get paid and to keep their company in the green, the only way they can do that is to, as you noted, keep putting their hands out. It is not in their best interest to produce a system that is self sufficient, it is in their best interest to keep you on the line.

    That said, it's not always practical to in-house everything, so a balance needs to be struck - keep the design and some worker bees in-house and then leverage vendors/contractors to spin up extra bodies for build cycles.

    Regarding your single point of failure concern - while valid, a properly designed ERP system with redundancies and load balancing should alleviate the core of that problem. Again, balance needs to be struck, while you want a single place to do all of your ERP functions, it doesn't always make sense to have them in one application that has to be customized to within an inch of it's life in order to do everything it needs to do. This needs to be addressed in the design phase to create logical business units that can sit on separate applications that, ex, communicate with the proverbial mothership via an API

    We are still going through this where I work. Previously IT was run on a bunch of Lotus Notes / Domino databases. Those have since been replaced by PeopleSoft and ServiceNow.

    You have to see the opportunity for what it is. You can have real conversations with the departments about what their real needs are. It is going to take a while, but you will have to produce documents that detail the core application functionalities for all of the applications. Then you will have to map those functions into the ERP system. Once you have done that, you will have your gap analysis and be able to focus your developmental resources. You have to get buy in from across the organization and get people committed to and willing to do things differently. The ERP equivalents of the current applications will not be apples to apples. If you try to do that, you will never get through it and will end up failing. If you are just going to recreate the apps, you might as well not even bother. The key is to focus on the functionality. Focus on the business needs / business cases for the applications.

    For something that big, you are going to need at least 3+ full time employees. A project manager to keep everything organized and fight back against scope creep, a senior developer / architect to make the technical decisions and provide guidance to the team of developer(s) who will do the actual work. In all honesty, what you are proposing is a significant investment for the organization and a shift in culture. Each one of those employees is easily a six figure salary, so figure over half a million dollar in salary (plus benefits, etc.) Good developers are hard to find and building a successful development team is a challenge. You will obviously need an executive sponsor who can help you figure out where to position this new group / department in the overall organizational hierarchy.

    The long term benefit to your organization is that you free yourself from the vendor. The risk that you run is that you might end up with incompetent developers or management on the new team and find yourself worse off than before.

    Have you considered bringing in another vendor? At the very least, you can use that as leverage to negotiate more favorable conditions with the current vendor.

    You should have enough experience with the current vendor to determine how accurate their project quotes are. Use that knowledge when you ask them for quotes on replacing / reproducing the current application functionality. Then compare that to what it will cost your organization to do it in house. It should be clear very early on in the process if you are going to save enough money to justify such a drastic realignment of the management, operation and development of the systems.

If you have good people (consultants or internal) then good things are possible no matter what choice is made. If you have bad people, it doesn't matter either.. the outcome was based purely on whether you have the knowledgeable people in a decision making role and in positions to actually do the work.

    Change the things that you're able to change and position yourself for the change that you can't. So that way, even though things don't go your way, hopefully you have a backup plan that is still possible in the event of failure.

You can bet the odds of this go up if you outsource the dev work. It's nothing for them to blame a third party they don't have a business relationship with.

At this point, having spent millions of dollars investing in your ERP it's not feasible to swap it out but it seems that most of the pain lies in the applications that MANAGE the data, the Excel spreadsheets, Access db's, etc. I would suggest looking into a front-end PaaS cloud solution with good dev and integration API's upon which to quickly re-build these apps, streamlining and standardizing processes and workflows - the situation you've described is a common case for cloud migration. You may want to look at a platform which will vastly improve time to app (Gartner and IDC have studies ballparking how much quicker you may realize time to app with a good cloud platform), lower your TCO and the OPEX vs CAPEX model may be more palatable to your accountants when evaluating costs of rebuilding.

It's a good platform to build upon, literally hands-free upgrades, with numerous dev integration API's that guarantee backwards-compatibility, better up-time than Google and various integration middleware solutions as well so you don't need to rewrite connectivity interfaces for all your apps if you ever decided to swap out Oracle ERP for say, SAP. And the language is fairly simple to develop in, simpler than say, Java so you could get your third-party SI to lay the groundwork and then maintain/build upon it internally or, depending on your internal IT team's capabilities, take the bulk of the work on yourselves.

The second is to take the ERP system and use existing business processes with minimal modifications and instead modify the ERP and/or put in place interfaces/API's to make the ERP work with the business processes. The answer is not always easy. Many places can benefit from business process transformation because processes have been used for a long time and don't take into account the current environment, they haven't been changed because "this is the way we've always done it". Sometimes the business processes are optimized and your better off changing the ERP and/or putting in the interfaces.
