How to Choose the Right MBSE Tool

Find the Model-Based Systems Engineering Tool for Your Team

A model-based systems engineering tool can provide you with accuracy and efficiency. You need a tool that can help you do your job faster, better, and cheaper. Whether you are using legacy tools like Microsoft Office or are looking for a MBSE tool that better fits your team, here are some features and capabilities you should consider.

Collaboration and Version Control

It’s 2018. The MBSE tool you are looking at should definitely have built in collaboration and version control. You want to be able to communicate quickly and effectively with your team members and customers. Simple features such as a chat system and comment fields are a great start. Workflow and version control are more complex features but very effective. Workflow is a great feature for a program manager. It allows the PM to design a process workflow for the team that sends out reminders and approvals. Version control lets users work together simultaneously on the same document, diagram, etc. If you are working in a team of 2+ people, you need a tool with version control. Otherwise you will waste a lot of time waiting for a team member to finish the document or diagram before you can work on it.

Built in Modeling Languages Such as LML, SysML, BPML, Etc.

Most systems engineers need to be able to create uniformed models. LML encompasses the necessary aspects of both SysML and BPML. If you would like to try a simpler modeling language for complex systems, LML is a great way to do that. A built in modeling language allows you to make your models correct and understandable to all stakeholders.

Executable Models

A MBSE tool needs to be much more than just a drag and drop drawing tool; the models need to be executable. Executable models ensure accurate processes through simulation. Innoslate’s activity diagram and action diagram are both executable through the discrete event and Monte Carlo simulators. With the discrete event simulator, you will not only be able to see your process models execute, but you will able to see the total time, costs, resources used, and slack. The Monte Carlo simulator will show you the standard deviation of your model’s time, cost, and resources.

Easy to Learn

It can take a lot of time and money to learn a new MBSE tool. You want a relatively short learning curve. First, look for a tool that has an easy user interface. A free trial, sandbox, or account to get started with is a major plus. This let’s you get a good feel for how easy the tool is to learn. Look for tools that provide free online training. It’s important that the tool provider is dedicated to educating their users. They should have documentation, webinars, and free or included support.

Communicates Across Stakeholders

Communication in the system/product lifecycle is imperative. Most of us work on very diverse teams. Some of us have backgrounds in electrical engineering or physics or maybe even business. You need to be able to communicate across the entire lifecycle. This means the tool should have classes that meet the needs of many different backgrounds, such as risk, cost, decisions, assets, etc. A tool that systems engineers, program managers, and customers can all understand is ideal. The Lifecycle Modeling Language (LML) is a modeling language designed to meet all the stakeholder needs.

Full Lifecycle Capability

A tool with full lifecycle capability will save you money and time. If you don’t choose a tool with all the features needed for the project’s lifecycle, you will have to purchase several different tools. Each of those tools can cost the same amount as purchasing just one full lifecycle MBSE tool. You will also have to spend money on more training since you will not be able to do large group training. Most tools do not work together, so you will have spend resources on integrating the different tools. This causes the overall project to cost a lot more. This is why Innoslate is a full lifecycle MBSE solution.


It’s important to find the tool that is right for your project and your team. These are just helpful guidelines to help you find the right tool for you. You might need to adjust some of these guidelines for your specific project.
