What makes a good IB Design Technology IA topic?

A good topic concerns an existing product that creates an observable problem for a specific, accessible user. The problem should be narrow enough to investigate through task analysis, product comparison, modelling, and repeated testing. You must be able to produce a physical fidelity model using the time, materials, tools, and skills available to you. Strong topics also lead naturally to measurable specifications involving factors such as dimensions, force, capacity, stability, time, or error rate. Most importantly, the topic must leave room for several feasible redesign concepts rather than assuming a final solution from the beginning.

Does the new IB Design Technology IA have to be a redesign?

For the course with first assessment in 2027, the design project begins with the redesign of an existing product. You identify and evaluate weaknesses in that product before developing a revised solution for an intended user. This does not mean changing only its appearance, because the redesign should respond to documented functional, ergonomic, accessibility, manufacturing, or sustainability needs. Students completing an assessment under an earlier syllabus may have different requirements, so they should check the course guide specified by their teacher. Do not rely on an online example until you have confirmed which assessment version it follows.

Can I redesign an app for my Design Technology IA?

A purely digital app is generally unsuitable for the current design project because students must create a physical fidelity model for testing and evaluation. A digital interface could form part of a wider physical product, such as the controls for an accessible dispenser or storage system. In that case, the physical product should remain central to the user's problem and your redesign evidence. You would need to test both the physical interaction and any relevant interface features instead of presenting screen designs alone. Confirm the proposed balance between physical and digital elements with your teacher before committing to the topic.

How complex should my DT IA product be?

Your product should be complex enough to support meaningful design decisions, but simple enough to model, test, and improve within the available time. Complexity does not earn marks by itself, and an advanced electronic system can weaken a project if it prevents reliable testing. A well-developed buckle, holder, container, or organiser can produce strong evidence about ergonomics, materials, mechanisms, and manufacturing. The best scope normally allows you to construct early models, discover weaknesses, and complete at least one evidence-based improvement. Choose technical features because the user needs them, not because they make the product appear impressive.

How many users do I need for an IB Design Technology IA?

The current criteria emphasize a primary persona, so you should have one clearly defined main user whose needs and task can be examined in depth. Additional users can provide useful comparative feedback, but they should not replace detailed access to the primary user. Select someone you can observe, interview, and consult during modelling and evaluation rather than someone available only once. If the product is intended for a wider group, your primary user can represent a carefully defined segment, but you should acknowledge the limits of that representation. Follow your school's consent, privacy, safeguarding, and image-use procedures whenever collecting user evidence.

Can sustainability be the main focus of a DT IA topic?

Sustainability can be a major redesign objective when it is tied to a specific product, user, and measurable problem. For example, you might redesign packaging for a local food seller to reduce material mass while maintaining grease resistance, stacking performance, and ease of assembly. A broad aim such as “make packaging eco-friendly” is too vague because it does not define what will improve or how success will be judged. Consider material quantity, durability, repair, reuse, disassembly, cleaning, and likely disposal rather than relying on an unsupported claim that one material is green. Your evaluation should also recognize trade-offs, since reducing material may weaken protection or increase manufacturing complexity.

Finding strong IB Design Technology IA topics is not mainly about inventing an impressive product. An effective topic starts with an existing product, a specific user experiencing an observable problem, and a redesign that can be physically modelled and tested using the time and facilities available.

For the course with first assessment in 2027, the IB design project requires students to identify, analyse, evaluate, and redesign an existing product for an intended user. This article explains the official requirements, presents feasible product redesign ideas, and shows how to turn an initial topic into a testable project.

What the current IB Design Technology IA requires

The revised Design Technology course began first teaching in 2025, with first assessment in 2027. Its IA is an individual design project allocated approximately 50 hours. It contributes 40% at SL and 30% at HL, although SL and HL students complete the same project requirements and are assessed using the same criteria.

The project follows five criteria:

Criterion A: Empathize
Criterion B: Defining the project
Criterion C: Ideation and modelling
Criterion D: Designing a solution
Criterion E: Presenting a solution

According to the official IB Design Technology curriculum update, students begin by evaluating and redesigning an existing product. They must develop a physical fidelity model that can produce evidence for testing and evaluation. The report has a maximum of 3,500 words, and the criteria carry 33 marks in total.

These details apply to first assessment in 2027. Students assessed under an earlier syllabus must follow the guide provided by their teacher because its project structure differs. The IB Design Technology course page identifies the applicable course versions.

What makes an IA topic workable?

A workable topic creates a clear evidence chain:

user problem → research → specifications → concepts → physical modelling → testing → justified redesign

Before committing, confirm that:

You can observe and consult a real primary user more than once.
The problem occurs during a specific task, not only as a general complaint.
You can analyse an existing product and identify meaningful weaknesses.
The investigation could produce at least three feasible redesign concepts.
You can construct physical models with available tools, materials, and skills.
Success can be measured through variables such as time, dimensions, force, capacity, stability, errors, or comfort ratings.
The scope allows iteration without specialist industrial equipment.

For example, “redesign a backpack” is too broad. “Redesign the strap-adjustment mechanism of an existing backpack for a student with limited hand mobility” identifies the user, product, task, and improvement opportunity. It also creates possible tests involving adjustment time, operating force, strap slippage, and comfort.

Use the RevisionDojo guide to choosing a strong DT IA topic as a feasibility check before beginning extensive research.

Feasible IB Design Technology IA topics

The best topics are usually modest in scale. Their sophistication comes from careful research, justified specifications, modelling, and iteration rather than unnecessary technical complexity.

Existing product	Specific user problem	Possible redesign	Realistic testing evidence
Desk organiser	A student has a narrow desk and cannot reach frequently used items	Vertical modular organiser with removable trays	Footprint, capacity, retrieval time, stability
Locker shelf	Items stacked at the back are difficult to see and retrieve	Sliding or rotating shelf insert	Access time, usable volume, supported load
Bottle holder	A wheelchair user cannot replace a bottle securely with one hand	Self-guiding holder with flexible retention	Insertion time, operating force, retention over uneven surfaces
Backpack buckle	Reduced finger dexterity makes conventional clips difficult	Enlarged magnetic or lever-assisted fastening	Opening force, closing time, accidental release, cycle durability
Tablet stand	A fixed stand causes poor viewing posture and occupies writing space	Foldable height and angle-adjustable support	Viewing angle, stability, adjustment time, packed size
Cutting board	A user with one functional hand cannot stabilize food safely	Removable food grips with a non-slip base	Movement, setup time, cleaning time, user confidence
Medication organiser	Small controls and similar compartments cause mistakes	High-contrast organiser with larger controls	Identification errors, opening force, completion time, spills
Food container	A tightly sealed lunch container cannot be opened independently	Levered lid or accessible pressure-release feature	Opening force, leak resistance, cleaning time, repeated cycles

These are starting points rather than ready-made IA titles. Each must be adapted to evidence from your own user, context, and product analysis. Your research should determine the final direction rather than being used to justify a solution chosen in advance. The RevisionDojo collection of DT IA examples shows how narrow constraints can support substantial development.

Turn an idea into a focused project statement

A useful project statement identifies the user, existing product, task, context, and failure. It should define the investigation without assuming the final solution.

A weak statement is:

I will design an ergonomic tablet stand for students.

A stronger statement is:

My primary user studies from a tablet on a 500 mm-deep desk. The existing stand places the screen below the user's preferred viewing height, occupies writing space, and becomes unstable during touchscreen use. I will investigate how it can be redesigned to improve adjustability, stability, and compact storage.

The stronger version leaves room for multiple concepts and identifies claims that can later be tested.

Plan testing before choosing the topic

Students often select an attractive product and only later consider evaluation. Reverse that process by writing at least five possible tests for every proposed topic.

Requirement	Appropriate test
Fits the available space	Measure the model and installation space in millimetres
Remains stable	Apply a controlled lateral load and record displacement or tipping
Can be operated independently	Conduct repeated timed trials with the primary user
Supports the required objects	Load specified items and measure total supported mass
Feels comfortable	Use a consistent rating scale with follow-up questions
Survives repeated use	Complete a fixed number of cycles and document wear or failure

A user rating alone is rarely sufficient. Combine subjective evidence with observations, dimensions, task duration, or another measurable variable. Repeated trials are also stronger than one successful attempt because they reveal reliability and variation. The RevisionDojo step-by-step DT IA guide explains how specifications, modelling, and evaluation should connect.

Topics and mistakes that create problems

Some topics are not automatically prohibited, but they introduce avoidable risks:

Buildings or entire rooms often exceed the product-redesign scope.
Complex medical devices introduce safety, ethical, and specialist-testing concerns.
Powered vehicles or large furniture may exceed available time, cost, and workshop capacity.
Apps without a physical product do not satisfy the physical fidelity model requirement.
Products for everyone prevent focused user analysis and meaningful testing.
Solutions selected in advance encourage students to fit evidence around a preferred idea.

Another common mistake is using vague specifications such as “lightweight,” “sustainable,” or “easy to use.” Replace them with justified thresholds and defined tests. Electronics should be included only when they solve a documented need, since a simple mechanism tested thoroughly is stronger than an unreliable sensor system. Review the common IB Design Technology IA mistakes before finalising your proposal.

Final topic approval checklist

Before committing, ask:

Can I document my primary user encountering the problem?
Can I analyse several comparable existing products?
Can I develop three genuinely different redesign concepts?
Can I make a physical model using school resources?
Can I test most specifications through repeatable methods?
Can I collect user feedback at multiple stages?
Is the product safe and ethical to prototype?
Is the scope small enough to permit meaningful iteration?

If several answers are no, narrow or replace the topic. A smaller project supported by strong evidence is more manageable than a complex product whose main claims cannot be tested.

Conclusion

The strongest IB Design Technology IA topics redesign an existing product for a real, accessible user. Select a narrow problem, confirm that physical modelling is feasible, and plan measurable tests before committing to a solution.

Fasteners, storage systems, kitchen aids, stands, holders, and containers work well because they support observation, ergonomic analysis, repeated testing, and visible iteration. RevisionDojo's coursework exemplars, IA guides, and Jojo AI can help you examine whether your proposed specifications and tests form a coherent evidence chain.
