Best of Breed refers to being, selecting, or using the best solution or software available for each specific function or business process, as opposed to using a single integrated system for multiple tasks. For example, an eCommerce business might choose:

• Shopify for its online store platform
• Mailchimp for email marketing
• Zendesk for customer support
• QuickBooks for accounting. 

The company integrates them to create an optimized workflow because each tool is considered the best in its respective category. 

Best-of-breeds is characterized by its flexibility as businesses can select the most efficient tool for each task based on their specific requirements, providing greater control over the technology they use. Best-of-breed solutions are also often innovative, as they offer new features and update more frequently than all-in-one solutions. And they optimize business processes more effectively which gives them a competitive edge in the market.

Managing multiple systems from different vendors can be a challenge. However, this can be counteracted with additional effort and resources to ensure effortless data flow and compatibility.
