If an app developer fails to release an app on the promised date, what negative action are they demonstrating?

When an app developer fails to release an app on the promised date, they are primarily demonstrating not keeping promises. This reflects a breakdown in their commitment to stakeholders, such as users and investors, who may have been relying on the developer's timeline. In business, keeping promises is essential for building trust and maintaining a strong reputation; when promises are broken, it can lead to dissatisfaction and a loss of credibility.

While other factors like planning, communication, and testing could potentially contribute to delays, the essence of the failure lies in the inability to adhere to the commitment made regarding the release schedule. Not keeping promises indicates a disregard for the expectations set forth, which is critical in maintaining relationships with customers who may feel let down by the postponed delivery.
