The bimodal IT model encompasses two simultaneous modes for application development and IT management processes: one traditional and one innovative. One focuses on core IT functions, developing stable and reliable applications, while the other is more experimental and focuses on agility. This encourages risk-taking and experimentation across the organization to generate new revenue streams.
There are scenarios where you have large, slower, complex systems and, on the other hand, smaller, more agile applications, which is called BiModal IT. Decoupling makes system development easier, since you not only have to think about improvements, but also about maintenance. BiModal IT provides you with an intermediate layer that gives large applications a scale of agility, type 1 focused on stability and efficiency, and type 2 agile and focused on release times, rapid application czech republic mobile numbers list evolution, and close alignment with business units.
Decoupling bimodal IT
BiModal IT type 1
In BiModal IT architectures, the first approach is where back-end systems are maintained by large development teams who develop and release in large versions (taking several months, if not years) once they are properly tested and proven. This architecture leverages the waterfall methodology, although it involves large development efforts. And therein lies the high risk and disruption exposure for your organization in case of system failures in these systems.
BiModal IT type 2
The second mode focuses on smaller teams, each with its own control of functionalities and components that can be released to production quickly in a matter of days. It is focused on differentiating how your organization interacts with your customers to deliver services that differentiate you from your competitors. And to do that, you need to have extremely high agility that can translate business ideas into real working systems. It is based on Agile methodology , with smaller frequent releases, small efforts, less exposure to risk, and little disruption to your organization in case of failure.
Conclusion
To ensure that both worlds can interconnect, you need to decouple the required functionalities between both worlds from your original systems. This is an interaction layer that ensures that the agile world can change (decouple) functionalities quickly without relying on older versions of the larger core system in your organization.
