ProcessModel—A Competitive Advantage
A process engineering tool for improving business processes. It has been said that nothing is more powerful than an idea whose time has come. ProcessModel is a process engineering tool for visualizing, analyzing, and improving business processes. Designed specifically for managers and planners, ProcessModel combines simple flowcharting technology with powerful simulation capability to bring flowcharts to life through graphical animation.
A decision-making tool. With the increasing challenge confronting businesses to improve their processes and the advent of powerful computing technology, computer simulation is emerging as a powerful decision making tool for process engineering. Simulation uses a computer to mimic a process in order to visualize and analyze its performance in terms of cycle times, throughput capacity, and resource utilization. ProcessModel gives you the best simulation information as a basis for your decisions.
A tool for trying out new ideas. Imagine being in a highly competitive industry and managing a manufacturing or service operation that is burdened by outdated technologies and inefficient work practices. To stay competitive, you know that changes must be made, but you are not sure what changes would work best, or even if certain changes will work at all. You would like to try out new ideas for improving your business processes, but recognize that this would be very time consuming, expensive, and disruptive to the current operation. ProcessModel can provide a way to run these tests efficiently.
A powerful tool for performing “what-if” analyses. Suppose that there were some cost and risk free way to rearrange any activity, reallocate any resource, or change any operational procedure. What if you could even try out completely new technologies and methods of operation? Suppose that all of this experimentation could be done risk free—without committing any capital, wasting any time, or disrupting the actual process. This is precisely the kind of capability that ProcessModel provides. This powerful tool lets you perform “what-if” analyses with a computer model of your process in compressed time giving you insight into ways to improve your processes that would otherwise be unattainable.
Why Use ProcessModel?
ProcessModel is quick and easy to use. It takes only minutes to learn because it uses basic flowcharting techniques. The on-line, context sensitive help system provides all the information needed to define your model quickly and easily. And the User’s Guide is full of examples of common modeling situations, giving you a repository of knowledge before you even begin.
ProcessModel is useful for improving all types of business processes including transaction processing, customer servicing, production and assembly operations, and transportation services. ProcessModel takes the guesswork out of decision making enabling you to make informed and confident decisions. Typical ProcessModel applications include:
• Staff scheduling and shift planning
• Task prioritization and interruption
• Method selection
• Capacity planning
• Lot sizing
• Appointment scheduling
• Job sequencing
• Production scheduling
• Productivity improvement
• Cycle time reduction
• Cost reduction
• Quality management
• Bottleneck analysis
• Activity and resource-based costing
• Resource scheduling for breaks and downtime
Another reason to use ProcessModel is that it provides replication analysis, user definable variables and attributes, and standard and customized reports.
Additionally, ProcessModel allows you to create hierarchical models to better organize and manage large modeling projects. Teams can define different parts of a complex model and then put them together to simulate the entire process. The possibilities are endless with ProcessModel.
To realize your best possibilities, ProcessModel makes available the power of special features: LIVE Animation™, OneStep™ modeling approach, and Visual Staffing™, as well as Process Optimization.
To communicate changes or visually evaluate your current processes. LIVE Animation™ stands for Life-like Validating and Envisioning Animation. ProcessModel provides much more than just blinking boxes. With ProcessModel, you can actually see people, paperwork, and other objects flowing through the system, making it easy to recognize bottlenecks and see how extensive they are. LIVE Animation™ is a powerful tool for communicating changes or visually evaluating your current processes.
OneStep™ Modeling Approach
To describe processes easily in a minimum of steps. Processes that are difficult or even impossible to define using other tools are easily described using ProcessModel’s OneStep™ approach. This modeling approach is designed to make modeling common processes as easy as one step. Other tasks are also reduced in complexity, so a minimum number of steps are required to define process logic.
To include people and resources in your model, so you improve the success rate of your implementation. ProcessModel gives you the ability to put people back into the process. Extensive staffing functions allow you to model any situation including the use of multiple resources or personnel. It is easy to use, allowing more people to become involved in the modeling process. ProcessModel is a great communication tool. By animating changes, employees will be able to visualize the effects of proposed changes on their jobs, making implementation easier.
To evaluate your existing ProcessModel simulation models and perform “what-if” analyses to find better ways to achieve the results you desire. ProcessModel uses the sophisticated optimization algorithms of the SimRunner application to help you optimize multiple factors simultaneously. By controlling input settings, ProcessModel will find the course of action that will optimize your entire system’s performance.

Setup & Installation
In this section you will find the necessary instructions to get your copy of ProcessModel installed and running on your system. Please Note that while you can run ProcessModel on the minimum required hardware, you should use the fastest PC (fast processor) with the most RAM that is available to you in order to enjoy faster simulation and smoother animation.
How To Setup the ProcessManager
ProcessManager is a stand-alone web based document management system hosted by ProcessModel, Inc. It runs independently from the ProcessModel application, though there is a link to the ProcessManager on ProcessModel’s File menu. Because it is web based, no installation is necessary on individual computers. After purchasing this application from your ProcessModel account manager, you will be setup with a company account which will be authorized for the specific number of user accounts you have purchased. Your login username will be your email address.
If you would prefer to host the ProcessManager and all associated documents yourself, you can purchase a version that can be installed on your own local server and access the application through your company intranet.
For a description of the benefits and features of the ProcessManager, See “ProcessManager”.
