Instructional Design and Rapid Prototyping: Rising from the Ashes of ADDIE
Tom Gram, one of my favorite bloggers, a few years ago responded to the hue and cry about ADDIE’s demise in the field of instructional design. In ADDIE is DEAD! Long Live ADDIE!, he talked about the love/hate relationship that many instructional designers and eLearning developers have had with ADDIE as they tried to keep up with business demands for speed and quality and as they observe process innovations such as rapid application development and iterative prototyping.
For many years the five ADDIE phases were the foundation for the design of most systems. Software engineering, product development, interactive/multimedia development are all based on some variation of the model. Most of these systems have evolved from the linear “waterfall” approach of early models; that is, a phase has to be completed and approved before you can start the next phase.
The waterfall approach has generally been replaced by iterative design cycles based on rapid prototyping, customer participation in the process, and loads of feedback loops built into the process.
And instructional design/e-learning has gone through the same process. It has evolved and continues to evolve to meet the needs of the marketplace. Much of the current hostile reaction to ADDIE is based on the old waterfall-linear approach and the assumed “instructivist” nature of the model.
ADDIE vs. Rapid Prototyping
ADDIE’s linear perspective provides a structured step-by step instructional design process. It is characterized by a progression through Analysis, Design, Development, Implementation, and Evaluation.
The process includes a cycle of revision for each phase of the training deliverables, offering clear guidance to the Instructional Designer and emphasizing the intrinsic logic of the design. It relies on two main assumptions:
- Quality information: The instructional designer can work on complete information from the Analysis phase, relying on the fact that the instructional context is stable and that there are no unforeseen events.
- Expertise: The instructional designer can master the process without errors, and all the team members (including subject matter experts) and stakeholders can give their contributions as required, at the right moment, and in a clear and unambiguous manner.
As we know, these are merely assumptions that are rarely, if ever, in place for an actual learning project.
Rapid Prototyping is currently the most popular alternate approach to ADDIE and traditional instructional design. With Rapid Prototyping, the steps are crunched together to reduce the amount of time needed to develop training or a product (Jones & Richey, 2000). The design and development phases are done simultaneously and evaluation is done throughout the process.
What exactly does Rapid Prototyping offer? Its non-linear approach allows for more instructional flexibility. It can catch problems early in the development stages as users are able to offer immediate feedback. It reduces development time and costs by:
- Using working models early in a project to eliminate time-consuming revisions later on.
- Completing design tasks at the same time, rather than sequentially, throughout the project.
With Rapid Prototyping, learners and/or subject matter experts interact with prototypes and instructional designers in a continuous review and revision process. The development of a prototype is the first step and analysis is continuous throughout the process. As one cycle proves effective and usable, the next cycle begins, based upon the best-practices of the previous cycle, and so on.
Analyzing needs and developing content depends in part upon the knowledge gained by actually building and using the prototype instructional system. Rapid Prototyping thus overcomes the limitations of the traditional ADDIE approach:
- It involves all team members earlier in the project cycle
- It allows the stakeholders, subject matter experts, and end users to provide early feedback.
The rapid prototype creates an early iteration loop that provides valuable feedback on technical issues, creative treatment, and effectiveness of instruction. The design document itself is changed to reflect this feedback, and in some cases, a new prototype module is developed for subsequent testing of the refinements.
Here is what it looks like:
Gram himself doesn’t use ADDIE in its purist form any more. For e-learning and performance applications, he prefers processes with iterative design and development cycles that are usually a variation of Rapid Prototyping such as the Dynamic Systems Development Method (DSDM) or, specifically for eLearning, either an iterative approach or Michael Allen’s Rapid Development approach.
He thinks of ADDIE not as an instructional design methodology but rather as a framework for coaching instructional designers and a project management process for managing learning and e-learning projects.
According to Gram, many e-learning designers these days are not formally trained in Instructional Design. Neither customers nor subject matter experts understand its systemic nature. Instructional Design is thought of as instructional “writing” more than the holistic approach at the heart of ADDIE. Instructional designers, customer, and subject matter experts are much easier to work with once they understand the broad project process that ADDIE represents.
Gram says that the ADDIE phases are the major processes that need to be managed and measured by most learning functions. He sees the integration of ADDIE with Rapid Prototyping as a starting point to design a customized process that can be communicated, executed, measured and repeated with some level of consistency. This integration demonstrates Instructional Designers’ continually improving processes, breaking through to better ways of working.
