MapleMBSE is an Excel-based tool that makes it easy for every stakeholder to engage with the Systems Engineering (SE) project without requiring them to be an expert in your primary SE tools. MapleMBSE makes broad engagement possible with Excel-based, task-specific interfaces for each activity in your SE project. By giving all stakeholders access to the process through a live, two-way connection to your systems model, you can ensure that all stakeholders can collaborate through the systems model, allowing them to work faster, avoid errors, and reduce unbudgeted costs.
