Which of the following describes two common approaches to implementing ERP systems?

• A. Local vs global deployment
• B. Best of breed and single integrator solution
• C. Open-source and proprietary
• D. Cloud-only and on-premises-only

Answer: (B)

Two common ways to implement ERP systems are best-of-breed and a single integrator solution. Best-of-breed means picking the strongest module for each business area (like finance, procurement, HR, etc.) from different vendors and tying them together. This approach gives you the ability to choose best-in-class functionality for each function and tailor the mix to fit specific needs, but it also requires more effort to integrate data and processes across multiple suppliers and to manage ongoing cross-vendor updates.

A single integrator solution, often an integrated suite from one vendor or a tightly aligned package delivered by a single system integrator, provides a unified data model and built-in cross-module workflows. The advantage is simpler, faster deployment and easier maintenance, with less risk of data compatibility issues. However, it can limit customization and may require compromises to fit every niche requirement.

The other options describe where you deploy or how you license and host ERP, not the fundamental strategy for selecting and coordinating modules across the system.
