or the vendor’s own consulting arm, if so qualified—will gener- ally spend less on implementation than will an organization that chooses an integrator with lesser skills or a poor track record in delivering services within budget.
Other factors come into play, such as the degree of stan- dardization of business processes among multiple facili- ties, and the organization’s track record in managing cross- functional business-change projects.
Complexity of the Software
Lastly, one other factor acts as a wild-card, in my opinion, in the ultimate cost of an ERP-software implementation project: the complexity of the software itself. This may or may not affect software license cost, but it often affects imple- mentation cost.
This may be easiest to define with an example. SAP and Ora- cle are two well-known, so-called Tier I ERP systems. It general- ly is understood that these systems can support the largest, most complex and most geographically dispersed organiza- tions. Also, they can support the widest number of industry sec- tors. They do this by incorporating a great deal of functionality for various industries, business processes and local regulatory requirements. These systems are highly configurable, with a big footprint.
This complexity comes with a price. It means that to make use of the system in a specific organization, many decisions must be made during implementation. These decisions cost time and money as experts configure the software and test it specifically for the organization’s needs.

This drives up the cost of the implementation.
SAP and Oracle are well-aware of this issue and have worked hard over the past decade to preconfigure their sys- tems for specific industries and uses. If a customer fits well into the vendor’s preconfigured templates, much of the complexity of the software can be hidden from view. Cus- tomers that fall neatly into these templates can sometimes
achieve very rapid and cost-effective implementations.
But don’t the higher-end software packages still cost more than software targeted for small and mid-size businesses? This is not always the case. I have seen situations where SAP and Oracle were actually the low-cost bidders. In cases where a software vendor wants the deal, it is not safe to assume that the higher-end pack- age will cost more. For this reason, I don’t believe software com- plexity in itself is a consistent factor in either software license cost
or implementation cost.
So, why do software vendors, customers or integrators continue
to use the implementation-to-license cost ratio? Because, as flawed as the ratio is, it does set expectations as to implementa- tion cost. To me, the ratio best works in hindsight—if a system implementation, on average, costs 1.5 times the cost of the soft- ware, a customer must not assume that it can do it for half the license cost. To really judge the prospective cost of an imple- mentation project, nothing beats performing a detailed esti- mate based on a realistic work-breakdown structure, with realistic estimates that account for the factors outlined here.
