Drawing upon thousands of documented use cases from the eLearning Brothers Customer Success team and Lectora’s product team, a new authoring methodology, called rapid Modular Development (ModDev), evolved and it provides the foundation for Lectora 21.


These Modular Development tools, which dramatically reduce time, save money, and extend resources with repeatable, scalable processes include:

  • Ready-made instructional design frameworks
  • Mobile-ready themes & style packs
  • Interactive wireframe templates
