The idea, meaning, and use of rapid prototyping differ across disciplines. This article discusses rapid prototyping in the field of instructional design.
Rapid Prototyping
Usually, instructional designing relies on following the linear ADDIE (analysis, design, development, implementation, and evaluation) model to develop an instruction or content. Rapid prototyping (RP) is an alternate, iterative design methodology to such a traditional, linear instructional design model. As the name suggests, it involves creating a prototype (working model of the final product); and just like any other prototype, it has the key features that get duplicated in the final (instructional) product.
RP is a way of designing content that involves creating a prototype, evaluating the prototype by seeking feedback from the stakeholders (learner, client, and the SME), implementing the feedback into the prototype, repeating this process of user evaluation and feedback implementation till the prototype evolves into an approved content by the stakeholders. This iterative design-evaluation cycle continues through the life of the project. Because of the repetitive, iterative process that RP follows, it is also called a spiral cycle or layered approach of instructional designing.
RP ensures developing effective instruction, especially in large projects, because of the stakeholder (student, client, and SME) involvement early at the design phase. Mistakes in the design are easier to fix at this stage than when the project is completely developed—it saves time, effort, and money to catch and fix the issues early.
Comparison
Traditional Instructional Design Model:
Step 1: Define concept (objectives, expectations, and audience) for the learning; Step 2: Define requirements of the learning; Step 3: Create a preliminary design; Step 4: Create the detailed design; Step 5: Develop the complete learning; Step 6: Implement or program the learning; Step 7: Test the learning for acceptance; Step 8: Correct the loopholes that got left out from Step 2.
In other words, the classic ADDIE model looks like:
Analysis -> Design -> Development -> Implementation -> Evaluation
[ADDIE follows a structured, linear, step-by-step, progressive approach through each of these five stages to come up with a particular content delivery or edition.]
RP Model:
Step 1: Define concept (objectives, expectations, and audience) for the learning; Step 2: Create a prototype; Step 3: Perform user evaluation and concept refinement; Step 4: Implement refined requirements; Step 5: Repeat Steps 3 and 4 in a continuous cycle.
In other words, the RP model looks like:
Information gathering -> Design Phase (iterative process: Design -> Prototype -> Review) -> Development Phase (iterative process: Develop -> Implement -> Evaluate)
[In a way, the design and development phases happen concurrently than sequentially in RP as compared to the traditional instructional design models. This makes the project cycle of RP shorter.]
Usage
You, as an instructional designer, can opt to use RP when you are struggling with time and budget for a learning project. Because of the stakeholder (learner, client, and SME) intervention at an earlier stage, mistakes are identified early; and therefore, the chances of rework at a later stage greatly reduce. The opposite often happens while following the linear, traditional models—the finished product often presents errors that need to be fixed—because these errors were not identified at an early stage, they replicate themselves all through the project subsections; and therefore, fixing them consumes a lot of time. In addition, in RP, the design and the development happen concurrently rather than sequentially. This translates to lesser time spent on the project, which also means you can complete the project on a tighter budget.
You can also use RP when you have two competing approaches of designing an instruction and you would like to get an idea about which approach would appeal and befit more to the learner.
Advantages
Getting feedback from the learners at an early stage: RP involves the learners early at the design phase. It is better to involve the learners to get their feedback than to believe that you can put yourself in learners’ shoes as much (and as well) as the learners themselves can. I believe that the self-critique of your work or instruction can never match to the feedback that you get from the learners. When you get the content evaluated by the learners and then implement their feedback, it improves your chances of delivering a more fit content for the learner. It makes you realize, at an earlier stage (design stage rather than the development stage), the mistakes or inefficiencies that might seep into the project. All this, saves time and increases effectiveness of an instruction.
Fine tuning yourself with changing client needs: Your client might have the most specific requirements and expectations when it first approaches you for developing content for a given audience. However, most often than not, client requirements and expectations change or evolve during the content development process. RP gives you an opportunity to assess whether the approach that you are following to design your content is in tandem with client’s requirements—fixed as well as changing requirements. (Every now and then, some client requirements or expectations are implicit. Because they are implicit, this information is only held by the client. When the client sees how the prototype is evolving, chances are that those requirements or expectations become explicit—for you as well as for the client.) A prototype that satisfies the client requirements is likely to result in a satisfactory finished (instructional) product. Get the client’s buy in and save expectation failures and later disappointments.
Accelerating the development process: Because RP seeks and incorporates the suggestions by the stakeholders (learner, client, and SME) early at the design phase, the development process gets quicker than it would have been if there were uncertainties about the stakeholders’ reactions to the design of the content. If content is developed with such uncertainties, the rework on the design and the developed content can be quite time and effort consuming. Introduce the stakeholders, catch the problems while they are relatively easy to fix, and reduce the time on content development.
Disadvantages
Approaching RP as trial and error: To some, following RP might appear as a trial and error method for getting a prototype approved by the client. While following RP, one needs to understand and constantly remind oneself that nothing can replace sound instructional strategy for a given learning situation and also that RP does not eliminate the need of an extensive analysis phase before heading for the design phase. So, RP is not a short cut to the instructional design and development process if you compromise on the sound instructional principles. Although using RP might give you a feeling that you can be less disciplined and repair the faulty designs by feedback, treating RP with this approach demeans the purpose and advantages of using RP—to create an effective instruction in lesser time.
Leading to frustration in developers: Because there are multiple iterations that happen in the design and developed content concurrently, some developers (content developers, graphic designers, and content technologists) might feel frustrated doing multiple revisions of the same content piece. Some might feel why leave a room for improvement and why not do everything in a perfect shape at the first go. However, that is neither the intent nor the approach that is followed for RP. Trying to achieve perfection the first time defeats the advantages of RP as well—to make design perfect, you will spend more time and effort; and also, you might try to fix the parameters in the prototype that need to be discussed with the stakeholders. So, to work on a RP project, it works well to have experience in RP or work with someone experienced in RP to understand where to draw the line of achieving perfection while developing the prototypes.

LIFTS Principle
It was only when I thought of writing about a simple set of principles called LIFTS, which I learned during the early days of my instructional design career, that I realized its nonexistence on the Internet. Just to confirm one of the aspects related to LIFTS, I thought of cross checking about it on the Web, and I was in for a surprise—there was not a single write-up about LIFTS on the Web. LIFTS is a simple set of rules that can be used for writing effectively for a given audience. It is an acronym that stands for Learner centric, Integrity, Flow, Transition, and Simplicity. This is what my grey cells recall. I would like to share whatever I can remember and I hope someone could correct me if I go wrong somewhere.
Let’s look at each of the elements of this principle or rule (I am not sure which categorization it fits into better) that can guide anyone to develop effective educational instructions for a specific audience or, in other words, learner.
L: Learner Centric
For any instruction to be effective (no matter at which level you are developing it: big, as in design phase of a learning project; or small, as in development phase of a learning project), it has to be learner centric. This principle affects multiple aspects of writing an instruction: what strategy you choose for designing the learning material (you would want to use different learning strategies for a drawing student vis-à-vis a busy, on-the-move technocrat); which examples or scenarios you select to teach the learner (they should be learner centric: the learner should be able to relate to them, they should be able to put themselves in the shoes of a person in the scenarios or examples that you develop for the learning); what kind of language you use to address the learner (I feel that addressing the learner as second person is effective while developing an educative instruction). Always consider the ultimate client for whom you develop the learning, the learner—everything else should revolve around this consideration.
I: Integrity
You cannot look London and talk Tokyo to the learner. All instructions that you include in learning should be integral to the overall goals of the learning. The objectives or goals should guide the assessments for the learning, and the assessments should guide the learning material. At all times, be relevant. You can teach a fashion student the impact of ineffective time management by taking an example based on an automobile company scenario; however, just think how relevant or related such content would it be vis-à-vis using a fashion company scenario to teach the same skill. Ensure that all learning instructions that you develop are directed to the learning goals and assisted by relevant examples.
F: Flow
The content of a learning should build logically as it progresses—from simple to complex, or from generic to specific, and not vice versa. This ensures that the learner is exposed to fundamentals before getting into the nuances of a subject—this is in sync with the natural and logical way of learning and developing schemas. While designing a learning, make sure that its topical outline reflects a seamless, progressive flow of subject knowhow. While developing a topic of a learning, make certain that all its subtopics follow a logical flow. Always arrange or organize your content to guarantee flow—it facilitates a smooth reading.
T: Transition
If Flow is macromanagement, Transition is micromanagement. Transition is how you move the learner from one topic or subtopic to the next one; how you relate the succeeding content to the preceding one; how you choose to tell the learner why a given content piece is important to be learned after a particular topic or subtopic. As a good practice, always include transitions for content chunks of all magnitudes such as paragraphs, subtopics, topics. Include a line or two sharing how a piece of content leads itself to the next piece of content, what is the importance of studying the forthcoming content, and so on. The idea is to interest the learner about what’s next, keep him or her aware of what to expect next, and let him or her know the reasons for the same.
S: Simplicity
Develop your instructions using simple language so that the learners can derive only one meaning out of it. The language should not be open to interpretations. Flowery language works well for fiction, not necessarily for imparting education and training. Use short, straightforward sentences; avoid convoluted structures in language.

Writing Effective Assignments
Although assignments appear at the end of each learning module, interestingly they are created before their preceding module content (text and media included).
After freezing the goals of a learning content, assignments are created, which is followed by the development of the reading content. Doing so ensures that (a) the assignments map to the goals or objectives of the learning content and (b) the reading content is streamlined and includes all the necessary information that the students need to be able to do the assignments.
For a content developer or an instructional designer, developing effective assignments ensures that the course goals are met and students develop competencies that the course promises. From my experience as an instructional designer, I feel the following guidelines can help you write effective assignments.
Work backward from the goals. While designing the assignment, remind yourself of the goals of the learning content. Think of the answers or solutions you would expect the students to produce in the assignment. Now think how to write the assignment so that the students are able to reach that answer or solution. Think what prerequisite(s) the students will need to perform the assignment in a manner that they get full grades for it---any information or job aid or sample, reasons of doing the assignment, where the assignment fits in the whole curriculum, what format to produce the assignment in, any word limits or length restrictions to the assignment, due date, grading criteria, and so forth. Include all these prerequisites as a part of the assignment. Working backwards from the goals ensures that (a) the assignment maps to the goals and (b) students are judged on the competencies that the course offers to develop.
Consider the skill level. When the course competencies and goals, say of an engineering-based course, are about enabling the students to apply (Bloom 3) the concepts of engineering in the field of robotics, you cannot put an assignment that asks students to create a robotic arm (Bloom 5) or write equations that govern the movement of a robotic arm (Bloom 1). Design the assignment so that it matches the desired skill level that a student is expected to achieve after going through the learning content.
Be specific: Writing vague, broad-ended (mind you not open-ended) questions would produce similar results. The students will respond likewise---with vague, broad, and varied answers. This not only makes the assessment of the assignment difficult, but also hampers the assignment mapping to the lesson goals or objectives.
Your assignment needs a precise direction---provide it yourself. Specify the students exactly what they need to do. For example,
Ineffective assignment: Comment on any one aspect of your choice in the Roman Empire.
Effective assignment: Identify four reasons for the fall of the Roman Empire. Explain each of the reasons. Document your response in a word document of not more than 1000 words. The assignment is due on Day X.
Give in details. Your students should be able to understand the assignment completely without asking for much help around. Do not leave room for assumptions, interpretations, and intuition-work by the students. They should be told what to do (steps, format, and naming convention of the assignment), why to do (purpose of the assignment), when to do (deliverable date of the assignment), for whom to do (expected audiences for the assignment; e.g., they should know whether they need to create a memo for their manager or an editorial for their local newspaper), and the associated brownies (grades and their split-up). In addition, the context building, if needed, should be elaborate and guide the student towards a specific answer. Remember that a detailed assignment guides students to specific answers, which in turn enable them to earn appropriate grades for the assignment.
Build relevant context or scenario. Place the assignment in the context of a typical job setting that a student will encounter after taking the course. For a student of fashion retail management, an assignment revolving around Sears or Macy’s or Ann Taylor (for devising an ‘effective sales strategy for the next season merchandise’) will help the him or her get the real feel of on-the-job experience and therefore make the student more prepared for the life after school. If, for this student, you build the assignment in the scenario of an automobile company (for devising an ‘effective sales strategy for their next model’), it would be irrelevant. Although the skill that the student would exhibit under the two scenarios would be the same (devising an effective sales strategy for products), using the relevant scenario (a) places the student in the shoes of the person he or she will likely become after taking the course, (b) checks the relevance of competency developed after taking the course, and (c) addresses the goals of the course in a better way.
Spread a long assignment across weeks. If you plan to include a lengthy assignment, it is wiser to split it up across different weeks and ask the students to execute its subparts each week. Such an assignment works well if it is a build-on type of an assignment; for example, if the course is on ‘Business Plans’ and the course objective states that the students will be able to build their own Business Plan after taking the course, a good assignment will be to ask them create a Sample Business Plan for a specific business and need. The business plan has many parts to it and creating all of it in one assignment or week might be stressful for the students; therefore, such an assignment can be spread over the weeks. Each week the student can be asked to create different parts of the business plan and in the last week, the student can be asked to compile the work of all weeks and improve or finalize it to submit a completed Sample Business Plan. This way, a lengthy assignment can be retained and the student load can also be balanced.
Weigh and word the assignment grading carefully. For each task, sub-task, and sub-sub-task that a student is asked to perform in the assignment, there should be a corresponding grading criteria. In addition, the grading points associated with each grading criteria should consider the effort and understanding that the particular task demands. The sum of grading points of all grading criteria is the total grade point of an assignment. In addition, word the grading criteria so that it maps to the task listed in the assignment. The verbs used in the grading criteria should map to the verbs used to perform the tasks. For example, if a task in an assignment is to “Provide at least two reasons for agreeing or disagreeing with the statement ‘XYZ’.”, then the corresponding grading criteria can be worded as “The student should have provided at least two reasons for agreeing or disagreeing with the given statement.” All tasks in the assignments should have a respective grading criterion and vice versa---students should not be assessed on anything not mentioned in the assignment. Doing it ensures that the students know what to do to achieve what.
Write inclusive instructor or facilitator notes. Often, instructors or facilitators of a learning course are not subject matter experts. They might just be responsible for holding or conducting a class or learning session with a set of notes provided by the educational facility. Therefore, your instructor or facilitator notes should contain detailed answers to the assignments and reasons for every trivial question and subparts of the assignment. Do not presume that the facilitator will know most of the stuff for a simple subject---just write as if the facilitator is going to need a lot of your help and so provide it at once in abundance.
