Slow builds and tests, combined with broken builds, leads to wasted time and effort.
Build infrastructure is often underutilized, and worse, not available during peak demand.
Complex, error-prone manual processes introduce risk and unpredictability, and divert attention away from coding.
Every team has their own non-standard non-compliant and standalone build processes.
Teams run their own build infrastructure means there is low utilization and no sharing of expensive hardware resources.
Every team needs a resident expert on each particular tool used in the Agile toolchain.
