Which review technique is likely to involve the least rigid process?

The walkthrough review technique is characterized by its relatively informal and flexible nature compared to other review methods. During a walkthrough, the author of the work typically leads a session where stakeholders or team members step through the material, discussing and clarifying aspects as they go. This participatory approach encourages open dialogue and can adapt fluidly based on the participants' questions and contributions, making it less rigid than more structured methods.

In contrast, techniques such as inspections and audits have defined procedures, often involving checklists and formal outputs. These methods prioritize thoroughness and adherence to specific standards, which can create a more constrained environment for discussion and modification. Technical reviews, while also structured, may focus on assessing the technical merits of a project or deliverable, often resulting in a more formalized evaluation process.

By fostering an environment of collaboration where feedback can be offered spontaneously, walkthroughs allow for a more organic exploration of the material, making them the least rigid review technique among the options presented.
