Deliverable-based billing and thinking can be problematic for operations roles, as there is often no specific deliverable to provide once the initial stabilization work is completed. This can lead to confusion for clients who may feel that nothing is ever truly finished, which is partially true due to the ongoing nature of the work.

Usually, the software starts with a single developer or a small team, who may have mid to senior-level experience and worked alone on smaller projects due to budget constraints. While this developer can quickly deliver the initial needs of the client, experienced software architects and project managers are rarely involved due to budget, time, and availability constraints.
