How to Evaluate Design Ideas
This techniques for evaluating a product is different. 1. Draw a mind map similar to the one below but ensure it applies directly to your project. 2. Add evaluation statements to each of the key areas. 3. Add pictures to enhance the overall presentation: 1 . Mar 30, · No product design is perfect; expect to get some customer feedback and need to make spur-of-the-moment changes. Look out for: Cramming too many functions into one screen. Using technology in key places that is not well supported by the majority of browsers.
As new consumer products are developed, product analysis helps you and others understand how -- and how well -- a product works given the price, competition and context.
Designers, industrial engineers, industry specialists and consumer advocates, such as journalists and bloggers, conduct product analysis. Writing product analysis entails assessing the product's function, conducting background research on the product and industry, and making an informed assessment and recommendation about the product's value and future in a well-organized report format. Choose a product to analyze. Either purchase a new product you already know will interest you or request a product from a distributor or the company for assessment; some companies give samples.
Gather the messages delivered with the product, such as the marketing and promotional materials as well as any information that a salesperson or website offers. What is the heat pump theory to grasp what the product claims to do through these messages and write them down. Use the product as it is intended for use. Decide whether or not it does the what it claims to do. Use it in multiple settings and ways.
Test further by giving the product to someone else and asking them to interact with it. Pay particular attention to the materials used, how they are shaped, formed and finished on the product. Record impressions and judgments about materials, durability, function and form on a notepad. Take notes on the product's aesthetic, anthropometric and ergonomic functions of the product. Analyze the way the product looks, how it fits with people's bodies and how it integrates pes 2013 how to install existing objects in a given situation.
For instance, a desk chair design may not be useful despite being comfortable or made from high quality materials if it fails to meet the average desk height. Summarize your experience using the product and your judgment on how well the product fulfills its intended design in a sentence.
Conduct background research on the industry segment. Go to a library or conduct an online search to gather details about the product including, but not limited to, the total number of households or companies using a product like this, competing products, industries producing this product, cost change or material change over time, ways that the product has been modified or migrated into other categories since its introduction to the market.
Research further competing products. Read reviews and product analyses written about these products and their benefits and deficiencies. Compare this to the noted benefits and deficiencies you assessed in the product you are reviewing.
Consider documenting this information using a spreadsheet or chart. Decide how the product fits in how to register for abn the existing market, and grapple with whether or not the variation or newness factors make it a worthy or valuable addition.
Summarize your main recommendation about the product in a sentence. Open a new document in a word processor. Write out the four major sections that will make up the paper: introduction, background, analysis and conclusion. Save the document. Begin the introduction by writing what the product is and summarizing your main argument and assessment, and why it is relevant to the intended audience.
Write the background section. List specific, objective features of the product you reviewed, such as price, materials and aesthetic qualities. Go on to include information about the industry and history of products such as this product. This section should give readers a broad understanding of this industry segment and how well the product you are reviewing fits into it. Write the analysis section, include two to three vivid examples from the testing period to illustrate your argument about your recommendation on the product.
Summarize your recommendation on the product with the conclusion. Reiterate your main argument about the product by echoing the introduction. Add additional recommendations, such as what you would like to see this product do further or what price the product should be for you to want to buy it. Proofread the product analysis and make any necessary grammatical changes.
Distribute the final draft as an email submission to a publication or consumer trade magazine or post on a blog or website for others to review. Assess the cost-value of a product even if you received it for free. Write product analyses about products or industries you are already familiar with or use. Read your product analysis out loud to a friend or family member to ensure it makes sense.
Always fully disclose to your audience if you received a product for free to maintain your credibility.

Approval and Implementation
The final page of a design folder is the 'evaluation'. The evaluation should describe all the good aspects of the product, those aspects that you feel have been successful. Your evaluation should also explain how the your product could be improved. The improvements outlined by the evaluation should describe ways in which the product can be improved for the next time it is manufactured. Jan 08, · Designers, design managers and educators also need an evaluation process when selecting creative ideas or different design layouts for creative projects. In order to achieve the best output of the selection process, an evaluation methodology should be considered to make sure that the selected creative or design . Evaluation research is both detailed and continuous. It pays attention to performative processes rather than descriptions. Research Process: This research design utilizes qualitative and quantitative research methods to gather relevant data about a product or action-based strategy. These methods include observation, tests, and surveys.
Learn to conduct a heuristic evaluation on any given user interface design. This article will teach you how to generate and conduct your own heuristic evaluations so you can improve the usability , utility, and desirability of your designs. Jakob Nielsen, a renowned web usability consultant and partner in the Nielsen Norman Group, and Rolf Molich, another prominent usability expert, established a list of ten user interface design guidelines in the s.
These heuristics have been reflected in many of the products designed by some of the most successful companies in the world such as Apple, Google, and Adobe. Nowadays, designers are encouraged to establish their own design-specific heuristics to evaluate their products, systems, websites, etc.
Since Nielsen and Molich developed these heuristics in the s, technology has advanced and they are less attuned to many of the products available in the market today.
For instance, Nielsen and Molich's heuristics would be too general to evaluate the usability of designs intended for online communities or mobile devices where the working environment is constantly changing.
However, the original heuristics are still largely applicable in spite of the specific capabilities and constraints of modern designs. Copyright terms and licence: Free to Use. In combination with market research, other design guidelines and requirements, using your company or product-specific heuristics will better suit the design under scrutiny.
Choosing and developing new heuristics is a task in itself; there are no fixed recommendations, as each design presents its own set of different tasks, constraints, functions, styles and other variables. However, most heuristic evaluations involve between five and ten items, which are chosen on the basis of their applicability to the overall usability of the system, website, application etc.
Less than five heuristics might lead to a lack of stringency when identifying potential problems and issues, but on the other hand, more than ten may overburden the evaluator as they must analyze the design with all of these heuristics in mind while the heuristics may also conflict with each other.
In a heuristic evaluation conducted by Jakob Nielsen in , results showed different evaluators identified different numbers and types of usability problems. Therefore, it is highly recommended that multiple evaluators are employed in a heuristic evaluation to ensure the highest possible detection rate so these usability problems can be solved before the final design is produced. Nielsen suggests that between three and five evaluators is sufficient because when the number of evaluators used increases, the number of problems identified increases in turn.
The general consensus is that more is better, especially when the evaluators have different skillsets i. In consolation, one or two evaluators are often sufficient in the early stages of development to identify the majority of usability problems. Copyright terms and licence: All rights reserved. The curve shows the proportion of usability problems identified increases as the number of evaluators used increases.
Like any suggested method in research and design, there are both pros and cons in the usability inspection method of heuristic evaluation. Generating your own heuristics is an important skill to have.
Heuristic evaluation can be a useful inspection method; however, some experts have identified issues with evaluators reporting false alarms, rather than genuine problem elements within designs. To limit the effect misreporting has on the applicability of findings from heuristic evaluation, it helps to use a number of different evaluators, collate their problems and carry out a debriefing session to root out false alarms at various stages in the design process.

Nielsen and Molich's 10 User Interface Design Heuristics Jakob Nielsen, a renowned web usability consultant and partner in the Nielsen Norman Group, and Rolf Molich, another prominent usability expert, established a list of ten user interface design guidelines in the s. Visibility of system status. Users should always be informed of system operations with easy to understand and highly visible status displayed on the screen within a reasonable amount of time.
Match between system and the real world. Designers should endeavor to mirror the language and concepts users would find in the real world based on who their target users are. User control and freedom. Offer users a digital space where backward steps are possible, including undoing and redoing previous actions.
Consistency and standards. Interface designers should ensure that both the graphic elements and terminology are maintained across similar platforms. For example, an icon that represents one category or concept should not represent a different concept when used on a different screen.
Error prevention. Whenever possible, design systems so that potential errors are kept to a minimum. Users do not like being called upon to detect and remedy problems, which may on occasion be beyond their level of expertise.
Eliminating or flagging actions that may result in errors are two possible means of achieving error prevention.
Recognition rather than recall. Minimize cognitive load by maintaining task-relevant information within the display while users explore the interface. Human attention is limited and we are only capable of maintaining around five items in our short-term memory at one time. Due to the limitations of short-term memory, designers should ensure users can simply employ recognition instead of recalling information across parts of the dialogue.
Recognizing something is always easier than recall because recognition involves perceiving cues that help us reach into our vast memory and allowing relevant information to surface. For example, we often find the format of multiple choice questions easier than short answer questions on a test because it only requires us to recognize the answer rather than recall it from our memory. Flexibility and efficiency of use. With increased use comes the demand for less interactions that allow faster navigation.
This can be achieved by using abbreviations, function keys, hidden commands and macro facilities. Users should be able to customize or tailor the interface to suit their needs so that frequent actions can be achieved through more convenient means.
Aesthetic and minimalist design. Keep clutter to a minimum. Therefore, the display must be reduced to only the necessary components for the current tasks, whilst providing clearly visible and unambiguous means of navigating to other content. Help users recognize, diagnose and recover from errors. Designers should assume users are unable to understand technical terminology, therefore, error messages should almost always be expressed in plain language to ensure nothing gets lost in translation.
Help and documentation. Ideally, we want users to navigate the system without having to resort to documentation. However, depending on the type of solution, documentation may be necessary.
When users require help, ensure it is easily located, specific to the task at hand and worded in a way that will guide them through the necessary steps towards a solution to the issue they are facing. Why You Should Evaluate Against Your Own Heuristics Nowadays, designers are encouraged to establish their own design-specific heuristics to evaluate their products, systems, websites, etc.
How to Generate and Conduct Your Own Heuristic Evaluation Choosing and developing new heuristics is a task in itself; there are no fixed recommendations, as each design presents its own set of different tasks, constraints, functions, styles and other variables.
Make sure to combine them with other relevant design guidelines and market research. Select your evaluators. Make sure to carefully choose your evaluators.
Your evaluators should not be your end users. They should typically be usability experts and preferably with domain expertise in the industry type that your product is in. For example, an evaluator investigating a Point-of-Sale system for the restaurant industry should have at least a general understanding of restaurant operations.
Brief your evaluators so they know exactly what they are meant to do and cover during their evaluation. The briefing session should be standardized to ensure the evaluators receive the same instructions; otherwise you may bias their evaluation. Within this brief, you may wish to ask the evaluators to focus on a selection of tasks, but sometimes they may state which tasks they will cover on the basis of their experience and expertise.
First evaluation phase. The first evaluation generally takes around two hours, depending on the nature and complexity of your product.
The evaluators will use the product freely to gain a feel for the methods of interaction and the scope. They will then identify specific elements that they want to evaluate. Second evaluation phase. In the second evaluation phase, the evaluators will carry out another run-through, whilst applying the chosen heuristics to the elements identified during the first phase. The evaluators would focus on individual elements and look at how well they fit in the overall design.
Record problems. The evaluators must either record problems themselves or you should record them as they carry out their various tasks to track any problems they encounter. Be sure to ask the evaluators to be as detailed and specific as possible when recording problems. Debriefing session. The debriefing session involves collaboration between the different evaluators to collate their findings and establish a complete list of problems. They should then be encouraged to suggest potential solutions for these problems on the basis of the heuristics.
Img The curve shows the proportion of usability problems identified increases as the number of evaluators used increases. Pros and Cons of Heuristic Evaluation Like any suggested method in research and design, there are both pros and cons in the usability inspection method of heuristic evaluation. Evaluating designs using a set of heuristics can help identify usability problems with individual elements and how they impact the overall user experience.
Cons of Heuristic Evaluation Choosing appropriate heuristics is extremely important; if the wrong set of heuristics is employed, certain usability problems may be overlooked. Heuristic evaluation might be relatively time-consuming when compared to other 'quick and dirty' inspection methods, such as simple walkthroughs with a small sample of users.
Training evaluators takes about a week on average, not including the time it takes to conduct the evaluations and debriefing sessions. Unlike cognitive walkthroughs, heuristic evaluation is based on preconceived notions of what makes 'good' usability. However, this need not be seen as a negative point, as heuristics are often based on the experiences of real users with hundreds of designs. Problems identified by evaluators can often be false alarms. The Take Away Generating your own heuristics is an important skill to have.
