Instructional design: what it is, models and how to apply it in e-learning

Instructional design is the systematic process of planning, structuring and developing learning experiences based on pedagogical principles. Its goal is to ensure that training does not merely transmit information, but produces real changes in people’s performance.

What is instructional design?

Instructional design is the process of planning, structuring and developing learning experiences based on pedagogical principles. Its aim is to facilitate the acquisition of knowledge, skills and competencies in an effective, measurable, and results-oriented way.

In practice, instructional design adds a pedagogical layer to content: it is not just about what to teach, but how to structure that knowledge so that learners acquire, retain and apply it. According to a study by the Association for Talent Development (ATD, 2023), organisations that apply a formal instructional design process achieve learning transfer rates up to 40% higher than those that produce content without a defined pedagogical methodology.

In a corporate training context, instructional design is the discipline that connects business objectives with learning objectives, ensuring that training delivers a measurable return on investment. A corporate instructional designer does not ask “what do I need to teach?” but rather “what performance problem do I need to solve, and how can training help?”.

Key concepts in instructional design

To work with any instructional design model, it is essential to master the field’s core terminology. These are the concepts every L&D team needs to know:

• Learning objectives: statements that describe what learners must be able to do by the end of the training. They should be written using observable and measurable verbs (Bloom’s taxonomy): analyze, apply, evaluate, create. A vague objective — “understand the importance of X” — is not a real learning objective.
• Bloom’s taxonomy: a reference framework that classifies cognitive objectives into six levels of increasing complexity: remember, understand, apply, analyze, evaluate, and create. It is the most widely used tool for aligning learning objectives with the actual complexity level of the content.
• Training needs analysis: a process carried out before design that identifies the gap between current and expected performance. It is the starting point of any rigorous instructional project and the foundation of the ADDIE model.
• Cognitive load: the brain’s limited capacity to process new information at once. Effective instructional design manages cognitive load by breaking content into manageable chunks, removing irrelevant information, and using multiple sensory channels in a coherent way (Sweller, 1988).
• Learning transfer: the learner’s ability to apply what they have learned in real-world situations beyond the training environment. It is the most relevant indicator of training effectiveness and the ultimate goal of instructional design.
• Formative assessment: ongoing evaluation that takes place throughout the learning process—not just at the end—with the goal of identifying gaps and adjusting the design. It includes check questions, decision-making scenarios, and practice activities.
• Scaffolding: an instructional technique that provides temporary support to learners as they acquire a new skill, gradually removing it as they gain autonomy. It is especially useful in technical or high-complexity content.
• Content mapping: a visual representation of the structure and sequence of training content, including its relationships and dependencies. It is the central artifact of the design phase in ADDIE and ensures alignment between objectives, content, and assessment.

Instructional design as a bridge between knowledge and performance

Having expert content is not enough for training to work. Without adequate instructional design, knowledge gets trapped in the material: learners consume it during the course but neither integrate nor apply it in their work.

Instructional design acts as a bridge across three key dimensions:

• Motivation and context: people learn better when they understand why they need to learn something and how it will help them at work. Good design always starts from the learner’s real work context, not from a list of abstract content topics.
• Prior knowledge: effective learning builds on what the learner already knows. Instructional design maps prior knowledge and defines anchor points for new information.
• Cognitive load: cognitive load theory (Sweller, 1988) demonstrates that the human brain has limited processing capacity. Well-executed instructional design distributes content in a way that does not overload working memory: chunking, progression from simple to complex, and eliminating irrelevant information are central strategies in this process.

Main instructional design models

There are several methodological frameworks for approaching instructional design. Each responds to a different context, urgency and level of resources. These are the most widely used in corporate environments:

ADDIE model

It is the most widespread and recognised model in corporate training. Its five phases — Analysis, Design, Development, Implementation and Evaluation — offer a clear, structured process that ensures coherence between objectives, content and assessment. It is the ideal starting point for complex or long-term projects. You can explore its application in depth in our complete guide to the ADDIE model.

SAM model (Successive Approximation Model)

Developed by Michael Allen as an agile alternative to ADDIE, the SAM model of instructional design works with short iterative cycles: prototype quickly, test with real users, and refine continuously. It is especially suited when time-to-launch is critical or when the team needs to validate hypotheses before investing in full production.

ASSURE model

Designed specifically to integrate media and technology into training, ASSURE is ideal when the delivery channel is a determining factor. Its phases include learner analysis, selection of technological media, and assessment of learning. It is commonly used in e-learning and blended learning environments.

Dick and Carey model

The most systematic and comprehensive model. It begins with a detailed identification of terminal and enabling objectives and defines with surgical precision every component of the instructional process. It requires a greater investment of time in the analysis phase, but produces training that is extremely well aligned with objectives. Recommended for critical programmes (safety, compliance, certifications).

Merrill’s Principles of Instruction (MPI)

Proposed by David Merrill in 2002, this model is based on 5 core principles that give the instructional designer the keys to guarantee learning:

• Task-centred principle: training should focus on real-world problems, adapted to the learner’s actual needs and how to solve them.
• Activation principle: training should stimulate the existing knowledge base, helping learners connect what they already knew with what they are about to acquire.
• Demonstration principle: training should present knowledge in a way that engages different regions of the brain, so that it is retained for longer.
• Application principle: training should provide the necessary tools for learners to apply new information on their own, practising and learning from their mistakes.
• Integration principle: training should offer opportunities to integrate knowledge into real situations through reflection, discussion and creation.

Gagné’s 9 Events of Instruction

Robert Gagné proposed nine events of instruction that must occur in any effective learning experience: gaining attention, informing learners of the objective, stimulating recall of prior learning, presenting the content, providing learning guidance, eliciting performance, providing feedback, assessing performance, and enhancing retention and transfer.

The value of this model in corporate instructional design is its universal applicability: it does not depend on a specific format, and works equally well in e-learning courses, face-to-face sessions, or blended programmes. Each event corresponds to a specific cognitive process that facilitates the integration and consolidation of learning.

How to choose the right instructional design model for your organisation

There is no universally superior model: the right choice depends on four variables you should evaluate before starting any training project:

• Urgency and time available: if you need to launch within weeks, SAM is the best option. If you have months and the project is strategic, ADDIE or Dick and Carey offer greater robustness.
• Content complexity: the more technical, regulated or critical the content (compliance, safety, certified skills), the more rigorous the model needs to be. Dick and Carey is particularly well-suited here.
• Team size and resources: iterative models like SAM require prototyping capability and rapid feedback cycles. Small L&D teams may find ADDIE more manageable for long-term projects.
• Digital maturity of the organisation: if you already have an LMS in place and established training processes, ADDIE will fit well within your structure. If you are building from scratch or in exploratory mode, SAM or ASSURE offer greater flexibility.

ADDIE model phases applied to corporate training

Although multiple models exist, ADDIE remains the most widely used reference framework in corporate L&D teams. Here are its five phases applied to a real organisational context:

1. Analysis

Training needs, the target audience, prior knowledge, technical constraints and the business objectives that training must support are all identified. A thorough analysis prevents producing irrelevant content. Key question: what must employees be able to do that they currently cannot?

2. Design

Learning objectives are defined (using Bloom’s taxonomy verbs), along with content sequencing, practice activities, assessment criteria, and the most appropriate delivery formats. This is the most strategic phase: errors here are amplified in subsequent stages.

3. Development

Materials are produced: scripts, videos, interactive modules, activities, assessments. This is where instructional design becomes real content. The quality of this phase depends directly on the soundness of the preceding ones.

4. Implementation

Training is made available to learners: via the LMS, in person, or in a hybrid format. This includes technical configuration, communication with participants, and support throughout the process.

5. Evaluation

Results are measured across four levels (Kirkpatrick): satisfaction, learning, transfer and business impact. Evaluation is not the end of the process: it is the starting point for continuous programme improvement.

Learner-centred instructional design

The learner-centred approach rests on a simple but powerful premise: content is not the centre of training — the learner is. This means designing with the learner in mind, not around what is being taught.

In practice, this approach translates into three design decisions that make all the difference:

• Grounding in real work context: examples, case studies and practice scenarios must be anchored in situations the learner recognises from their everyday work. A salesperson learns better through a simulation of real objections than through theory about sales techniques.
• Activating prior knowledge: before introducing new information, instructional design must create connections with what the learner already knows. This reduces cognitive load and accelerates the integration of new knowledge.
• Designing for action, not information: the goal is not for learners to know more, but for them to do something differently. Every module should end with an application activity that requires the learner to mobilise what has been learned in a practical context.

Instructional design and current e-learning formats

Instructional design does not exist in isolation from the format in which training is delivered. New digital formats offer pedagogical possibilities that classic models could not leverage, but they also require instructional design to adapt to their particularities.

Microlearning and learning pathways

Breaking content into short capsules (5–10 minutes) enables flexibility, reduces cognitive load per session, and reinforces retention through spaced repetition. The instructional design of a microlearning pathway must define the sequence of capsules, reinforcement points, and progression criteria.

Social and collaborative learning

Fostering peer exchange spaces (forums, group challenges, collaborative projects) extends the impact of training beyond formal content. Instructional design must anticipate how to integrate these interactions into the learning flow.

Gamification applied to design

Incorporating game mechanics (points, badges, levels, leaderboards) into instructional design increases motivation and engagement — provided they are aligned with learning objectives and do not become an end in themselves.

Accessibility and mobile first

Updated instructional design must factor in accessibility (WCAG 2.1) and mobile experience from the outset. This is not a final adaptation step: it must be a design constraint from the very beginning of the project.

The importance of instructional design in creating effective courses

Instructional design plays a crucial role in the effectiveness of any training programme. It is not an optional phase or a luxury reserved for large organisations: it is the necessary condition for training to produce measurable results.

Here is why instructional design is so decisive:

• It aligns training with business objectives: without a formal analysis and design process, courses frequently address perceived needs rather than real ones. Instructional design forces you to define the expected impact first, then design the path to achieve it.
• It improves retention and transfer: Ebbinghaus’s forgetting curve shows that without active reinforcement, we forget up to 70% of what we learn within 24 hours. Instructional design incorporates spaced retrieval strategies, active practice and contextual application that counteract this process.
• It reduces production time and cost: well-defined design before production prevents costly revisions during development. The time invested in design is recovered many times over during production.
• It increases completion and engagement: courses designed with instructional design principles have significantly higher completion rates. Learner-centred design, with real context and application activities, creates perceived relevance — the primary driver of engagement.

Common mistakes in instructional design (and how to avoid them)

Even with the best models available, there are recurring mistakes that undermine training effectiveness. Identifying them is the first step to avoiding them:

• Skipping the analysis: the most frequent mistake. Going straight to content production without having identified real needs, the target audience and performance objectives produces irrelevant courses that nobody completes. Analysis is not a bureaucratic formality: it is the investment that makes all subsequent phases worthwhile.
• Vague learning objectives: “the learner will understand the importance of X” is not a learning objective — it is an intention. Objectives must use observable and measurable verbs from Bloom’s taxonomy (analyse, apply, evaluate, create) and specify the expected performance level.
• Content without practice activities: presenting information with no opportunities for active application is the digital equivalent of a four-hour lecture. Practice is what converts information into competence.
• Ignoring the learner’s context: designing without knowing the audience profile — prior experience, work context, motivation, time constraints — produces generic training that does not resonate with those who need to learn it.
• Not measuring results: training without impact evaluation is a black box. Defining how to measure success must be part of the design from the outset, not an afterthought.
