The Agile principles looked great but they were mere guidelines. As the software development industry evolved with Agile, some issues were identified.

• Development, Operations & Security teams were working in independent silos.
• There was a dependency on the operations team to promote code through different environments.
• Implementation and Rollback plans were complex and there were high chances of failure.
• There was a dependency on the infrastructure team to provision repeatable and consistent environments (For ex: VMs, DBs, etc).
• Security reviews were done at the end of the software development life cycle. This introduced unnecessary delays and impacted time to market.
