Trust is the foundation of any successful collaboration, especially between the business and development teams, who often have different perspectives, expectations, and incentives. Trust exists when everyone can confidently rely on one another to act with integrity, particularly in times of difficulty. Without trust, it is impossible to build high-performing teams and trains or build (or rebuild) the confidence needed to make and meet reasonable commitments1. One way to gain trust between the business and development is to deliver predictability, which means that the teams and the Agile Release Train (ART) can consistently deliver value in the shortest sustainable lead time, with the best quality and value, and meet the agreed-upon objectives and goals2. Predictability is achieved by applying the SAFe principles and practices, such as aligning to a common mission and vision, planning and executing in iterations and increments, applying systems thinking and feedback loops, and embracing change and innovation3. Predictability helps to establish and maintain trust between the business and development, as it demonstrates the reliability, transparency, and accountability of the teams and the ART, and it enables the business to make informed decisions and provide timely feedback4. The other options are not the best ways to gain trust between the business and development, as they either do not address the core issue of trust, or they may have negative consequences. Automating the delivery pipeline is a technical practice that supports DevOps and continuous delivery, and it can improve the speed, quality, and efficiency of the value delivery, but it does not necessarily build trust between the business and development, as it does not address the communication, collaboration, and alignment aspects of trust. Releasing new value to production every day is a desirable outcome of DevOps and continuous delivery, and it can provide fast feedback and validation of the value delivered, but it does not guarantee trust between the business and development, as it may also introduce risks, errors, and instability, and it may not reflect the actual needs and expectations of the customers and stakeholders. Maintaining iterations as a safe zone is a practice that protects the teams from external interference and distractions during the iteration execution, and it can help the teams focus on their work and deliver value, but it does not foster trust between the business and development, as it may also create silos, isolation, and resistance to change, and it may prevent the teams from collaborating and communicating with the business and other teams.
