When Bergman and Moore created their model, they were able to identify the model's potential problems and challenges, and overcome many of them. But not all of the model's potential shortcomings could be anticipated at the time of its creation, and not all of them were successfully overcome. An exploration of these challenges, both old and new, adds to an understanding of the model's overall modern-day viability, and provides valuable insight to instructional designers considering the model's effectiveness in realizing their own unique instructional goals.

Disadvantages of the Bergman and Moore ISD model include:

1. High cost of multimedia development. In regards to the high cost of interactive video disc and multimedia development in today’s society, we can see that there are still major costs involved. The costs may not be as great as when the model was first introduced, depending on the application, but with all its constraints and requirements, this model is not cost effective.

2. High degree of developmental experience required. The lack of developmental experience is still a great disadvantage in our work force. Employers do not want to spend extra money training personnel, when there is a giant pool of educated unemployed workers. The problem with this is that not everyone is going to have the same experience or knowledge to help a company maintain and enhance their employees work performance and efficiency.

3. Potentially unmanageable in terms of scope. This model is not just dependent upon multiple people, but multiple languages, systems and interfacing between each. The model's designers compare the varied staff involved as musicians, noting that each not only "plays a different instrument, but also speaks a different language."  From instructional designers to graphic artists to video producers to computer specialists, all with a unique vernacular, the sheer scope of such an endeavor can be unmanageable.

4. Design process and steps overly complex. The model's 28 steps represent a challenging web of relationships and sequences that at both first glance and at further analysis, both then and now, seem quite daunting.

5. Narrow focus on AV and Tech production. The model has a unique focus on AV and Tech production, and as such, is limited those applications. This lack of versatility creates a problem for instructional designers looking for a "one-size-fits-all" instructional design solution.

6. Easily bogged down. The model is built on documentation, and despite attempts at organizing the voluminous degree of detail the model requires, the process of documenting the documenting itself can mire the production process down.

7. Dependent on ever-changing variables (applications, standards, technology). For example, computers seem to change daily, and Bergman and Moore saw that with new software also came a need for new hardware. Within a year most computers are outdated and unable to install new programs or updates crucial for trainings. When a company is trying to conduct trainings, it is harder for them to be successful when other offices may not have the current technology that they are using. They also may find their computers obsolete with new software being required.
