Methods, systems, and techniques for configuring customizations to legacy tasks as part of modernizing such tasks are provided. Example embodiments of a Role-Based Modernization System (“RBMS”) provide tiered configuration so that end users can be provided with tools with which they can further modernize legacy tasks in ways that do not tamper with the integrity of the system. For example, in one embodiment at least two configuration levels are available: (1) an administrator level that can control and configure aspects of the RBMS such as the legacy and non-legacy tasks associated with a particular role and defining what tools will be provided to the end user level and (2) an end user level. Example embodiments provide an RBMS, which uses these enhanced modernization techniques to provide role-based modernization of menu-based legacy applications.
