Mechanics: We show this refactoring on a BPMN model. Example: An example of the above bad smell appeared back in Figure 1 at the top, which shows the process of requesting and verifying credit card data for reservations at. Motivation: The system activity that verifies all data in an input form after it has been submitted could be anticipated and triggered as the user fills each of the form fields, thus to improve efficiency and effectiveness, since the user will not wait to receive feedback when entering erroneous or incomplete data. Bad Smell: Users repeatedly filling a form because of subsequent failed validation. B1) B1.a) Anticipate a validation activity Intent: Effectiveness, Efficiency, Satisfaction and Context Coverage. Example: The option to save a post in a blog server (i.e., Blogger, Wordpress, etc.) allows the user to start an activity, suspend it and resume it later, providing the possibility to review the post as many times as necessary before publishing it.
This may result in an improved efficiency and a better user satisfaction, especially when a given activity is particularly complex and requires time to be completed. Making an activity suspendable enables the user to pause the process during the execution of that activity and restart it afterwards, from the same point, possibly using a different device.
