    • Why an implementation memento ? To integrate Open ERP, two radically differentOur experience has shown us that the approaches can be applied. The package approachimplementation speed varies from simple to is an integration mode that is low cost, generic, withdouble depending on the methodology used for few developments to be done. This approach goesimplementation. The methodology is therefore from Open ERP generic to customers needs. Ancrucial to reap the full benefits of an implementation. important point here is that your finality is not to describe the clients current processes but an OpenKeys benefits of an efficient methodology ERP solution. At the opposite a custom approach isare: used when the clients business is weakly cover by Open ERP generic. This approach goes from1. Faster company growth. customers needs analysis to Open ERP solution. it isFrequently the implementation process is decelerate usually reserved for very large projects.because of a bottleneck issue related to HR. As anexample, a key projects manager is usually in In the following, we describe a methodology for thecharge for every steps of the implementation.

This situation forces some profitability of your Open ERP projects by applying acompanies to refuse projects. package approach.To grow faster, you must reduce dependence onhigh-level managers by the distribution ofmanagement between multiple profiles. Implementation phases:2. Quicker delivery.ERP integrations are complex. An efficientmethodology allows you to specialized roles and gettrained employees that are quickly ready to deliver.3. Risk mitigation.By working through a systematic approach, you cancontinuously improve yourself. Copyright © 2010 Open Object Press - All rights reserved
