If you’re looking to implement agile development in your software business, I encourage you to start small and learn from your experience. There are many resources available to help you get started, including books, articles, and online courses.
One helpful resource is the Agile Manifesto, which outlines the key principles of agile development. You can find the Agile Manifesto at https://agilemanifesto.org/.
I would also encourage you to connect with other agile practitioners in your community or online. There are many agile user groups and conferences where you can learn from others and share your own experiences.
