Deciding whether to build a capability in-house or partner with another company is a critical decision for businesses aiming to provide enhanced services without straying from their core competencies. Partnering can be advantageous when a company lacks expertise in a specific area, cannot support customization at scale, or needs to move quickly without sacrificing quality. For instance, Shopify and Stripe successfully leveraged partnerships to focus on their core strengths while still meeting customer demands. However, if a capability is central to a company's value proposition, building it internally might offer more control. Ultimately, partnering allows companies to focus their resources effectively, ensuring they deliver value to customers without diluting their unique offerings.
