10 Good Excuses for Not Reusing Enterprise Code

In enterprise IT organizations with multiple development teams, code produced by one team is potentially useful to others. Such code could be, for example, a parser for common XML documents, a service for converting image files on the fly, or utility methods for validating key business data. (Note that I'm using the term "code" loosely to mean any sort of artifact produced by a development team, including libraries, executables, and live services.) In the interest of reducing development time and costs, enterprise architects may seek to establish a code reuse policy.

But simply declaring that "all teams should reuse code whenever possible" is not going to accomplish much. There are likely cultural barriers to remove and new incentive structures to establish to make code resuse both possible and advantageous to development teams.

To determine what specific changes are necessary in your enterprise, consider the following good excuses for not reusing enter

Liberating an API Codebase from Swagger Annotations

When creating an API with accompanying Swagger documentation, two general paths can be taken:

1. Build First: Implement the API --> add Swagger annotations --> generate the UI and clients from the annotations
2. Design First: Design the API spec in Swagger YAML or JSON --> generate the UI, clients, and server stubs from the spec --> implement the server stubs

On my recent project, we had embarked down the "Build First" path. After implementing the API using the mighty Spring Boot, we integrated Swagger using the slick SpringFox library, as widely demonstrated in numerous blog posts.

  "Flavius Josephus was a roman historian of Jewish origin. During the Jewish-Roman wars of the first century AD, he was in a cave with fellow soldiers, 
  40 men in all, surrounded by enemy Roman troops. They decided to commit suicide by standing in a ring and counting off each third man. Each man so 
  designated was to commit suicide...Josephus, not wanting to die, managed to place himself in the position of the last survivor.

  In the general version of the problem, there are n soldiers numbered from 1 to n and each k-th soldier will be eliminated. The count starts from the 
  first soldier. What is the number of the last survivor?"
