Unformatted text preview: approaches built on the notion that the goalposts are always moving. The software development community has developed Agile methodologies based on that premise. Agile projects use multiple, short-term iterations or release cycles, directed by relatively simple requirements or “user stories” that evolve with each development cycle. When implementing EHR systems, consider adopting Agile software development methodologies so your implementation can stay current with best practices. This is a case where healthcare providers can leapfrog their counterparts in other sectors. Using modern, SOA technologies and iterative development practices, healthcare providers might teach their counterparts in other sectors best practices in enterprise agility.
