Refactoring

Over a period of time, there will be a need to realign context boundaries, domain events, APIs, and so on. There tends to be a stigma associated with things not working perfectly the first time and justifying the need for refactoring at the inter-component scale. However, this may be required for multiple reasons outside our control, ranging from competitor ecosystem changes, evolving/misunderstood requirements, inability to meet non-functional requirements, organizational and team responsibility changes, and so on. Hence, refactoring is a core discipline that software teams will need to embrace as a first-class practice.

Note

We are covering only the strategic (inter-component) aspects of refactoring in this chapter. There are several great works on the tactical (intra-component) aspects of refactoring, such as Martin Fowler’s Refactoring (https://refactoring.com/) book and Michael Feathers’ Working Effectively with Legacy Code, among others.
