Question 3 (Mandatory) (1 point) 'Zero defects' states that there is no tolerance for errors within the system. Its stated goal is that all processes are to avoid defects in the product or service. Companies often try to refine their product production methods with the goal of achieving six sigma error-free (which is another way of saying no less than 3.4 defects per million units). As with production, quality concerns are also very important within project management; however, often considerably higher levels of defects and quality issues are encountered in a project's final product. Which of the following is not a valid reason for a reduction in quality within a project management environment? O Pre-production environment Zero defects works best in a production environment where the process can be studied and improved over time. As projects are unique, often only a single issue of the product is made, thereby negating any opportunity to refine the process. O Triple constraint: On projects, quality is not the only constraint that the project manager needs to deal with; on- time and on cost demands often trump the desire to optimize quality. 0 Unclear requirements: Often, project outcomes evolve during the course of the project, as the initial ements were unclear. This results in a final deliverable that is more of a prototype than a final product. o Risk and quality mix: Managing project risks is usually given a higher priority on projects than managing quality - therefore, quality is not considered necessary for project success al
