The MMIS Systems Dilemma
White Paper by Dr Roger Oren, PhD PMP
Some vendors within the Medicaid program have marketed solutions, updating their Medicaid products with newer technologies. However, the efforts have been plagued with failures. The system replacement projects are generally over-budget, late, and often function poorly. Cost and schedule overruns up to 200% of their estimates are common in the Medicaid sector. When a system update is required, the whole application, spanning all Medicaid business units, is replaced creating a situation where the entire organization undergoes the chaos of a new system.
Medicaid Directors find the Medicaid computer systems difficult to manage. The computer applications are so complex that no single person can fully understand what the application is doing. In an attempt to deal with this situation, the Medicaid computer application has been divided into a series of sub- systems, such as Enrollment and Eligibility, Claims, Encounters and so on, which teams of developers work on in their various silos. Working in silos isolates and may inhibit the collaborative efforts. Also, it doesn’t help since the underlying architecture of the Medicaid system is a monolithic construction which makes any work expensive and difficult.
The Solution: Medicaid as a Service (MaaS)
The Medicaid system is composed of various functional silos which are tightly woven into the overall Medicaid computer application. As such, the application is difficult to change, and when changed, often produces poor results due to unforeseen downstream affects within the system. If this were not enough, the application itself is usually written in a computer language and architected in a manner which causes the application to be brittle, making it liable for failure when business changes are necessary to be made within a sub-system for compliance or program needs.
Enabling Infrastructure allows you to have high- availability with high-flexibility due to its construction.
For this reason, Enabling Infrastructure is needed. Enabling Infrastructure allows you to have high- availability with high-flexibility due to its construction. You need to have a contemporary architecture which enables a plug-and-play type of activity, similar to how individual Lego blocks can be removed, replaced and interlocked with the existing structure. This construct allows an organization to update their applications piece-by-piece, which localizes the chaos of a system change effort to a single business unit versus seeing the entire organization in disarray.
The ideal product for this type of Enabling Infrastructure is the Enterprise Service-Oriented Architecture Bus (ESB) product. Fortunately, there are a host of organizations, from proprietary to open-source, which have developed ESB products, several which are running today’s Internet architecture as well as running today’s organizations daily business transactions.
Steps to the solution
The following outlined steps are suggested in order to plan for and implement a Medicaid application which will comply with the MITA architecture, be modular, flexible and ready for emerging technologies, such as mobile device use.
1. Obtain an Integrator
The organization must procure an Integrator who is a visionary while able to easily use the technology at hand, such as an ESB. The integrator should also be well versed in Program and Project Management (PM) tools, techniques and methods, including using PM Metrics, such as Earned Value and Earned Schedule. Finally, the integrator should be able to grasp and understand organizational behavior and culture in order to successfully implement the change efforts required with modularity.
2. Integrator aids Agency in Services
The Integrator must have the skills to develop a Service-Oriented Architecture Center of Excellence. This is an essential step in order to develop the ESB charter, methodology, and staff necessary for an Enabling Infrastructure to function in operational environments.
3. Iterative Development – Decide what functional area to implement as a first step
The Integrator, with consultation to the Medicaid Executive Team, decides upon the first functional area to implement Enabling Infrastructure. For example, the team may start with a Provider implementation, plugging the application in the Infrastructure and then hooking it into the back-end legacy Medicaid application.
4. Repeat Step no 3
The team selects another functional area for implementation, such as Claims, plugging this application into the Infrastructure which integrates it into the new applications and the legacy system.
