In software development, one of the biggest challenges is creating products that meet the real needs and expectations of users. Developers and designers are often faced with the question: Who are we actually building this software for? While traditional audience analyses provide broad demographic data, personas take it a step further.
Personas are fictitious but realistic user profiles based upon real data and user research. They represent different user groups with specific characteristics, needs, goals and behaviors. Instead of relying on mere averages, personas create detailed characters with individual stories, offering a deeper understanding of the user perspective. An example of a persona (greatly abbreviated) could look like this:
- Name: Lisa König
- Age: 32 years
- Occupation: Marketing manager
- Technical affinity: High, uses modern software solutions daily
- Goals: Efficient management of marketing campaigns, routine task automation
- Challenges: Overwhelmed by complex software, little time for extensive training
This initial draft of a persona can provide an important basis for decision-making for a software team developing a marketing tool.
Why are personas important?
Using personas has several key advantages:
- Better user-centricity: Personas help teams consistently align with the needs of real users. Instead of addressing an anonymous “target group”, developers and designers can concretely imagine who they are optimizing software for.
- Improved communication within teams: Different departments (development, design, product management, marketing) often speak different “languages”. Personas create a common ground and ensure a uniform understanding of user requirements.
- More targeted product decisions: Features, designs, and workflows can be better validated using personas. Instead of speculating on whether a feature is useful, the team can ask specifically, “Does this feature help Lisa do her job more efficiently?”
- More effective UX and UI design: By mapping typical user behaviors and expectations, personas can make user interfaces more intuitive and accessible.
- Reducing development errors: Undesirable developments often occur when software is developed without the actual users in mind. Personas help avoid these missteps by consistently incorporating users’ perspective into the development process.
- Better marketing strategies: In addition to product development, personas are also helpful in marketing. They make it possible to create more targeted campaigns and content that are precisely tailored to relevant user groups.
Personas are much more than just nice add-on documents – they are an indispensable tool for successful, user-centered software development. They help teams put themselves in the perspective of real users and ensure that products are not only technically sophisticated, but also intuitive, useful, and engaging. In the following sections, we will take a closer look at how personas are developed, which methods have proven themselves and how they can be integrated into Agile development processes.
Differences and differentiation from classic target group analysis
In software development and marketing, it is essential to understand the users’ exact needs. While classic target group analysis is a proven means of segmenting potential customers or users, the personas approach goes one step further. The difference between the two concepts lies not only in the depth of the analysis, but also in the way they are used.
Audience analyses are often based on demographic and statistical data. They divide people into groups that have similar characteristics, for example in terms of age, gender, income or occupation. A typical audience description for a fitness app might be: “Men and women between the ages of 25 and 45 who exercise regularly and have an above-average income.” While this information helps to make a rough market segmentation, it leaves open what individual needs and behaviors exist within this group.
Personas, on the other hand, go beyond this general description and try to make a specific person from the target group tangible. A persona for the same fitness app might look like this:
- Name: Lisa, 34 years old, working mother
- Motivation: Wants to stay fit, but has little time for long workouts
- Challenges: Must integrate training sessions into a busy everyday life
- Expectations of the app: Short, effective workouts with ease of use
The big advantage of personas is that they illustrate a detailed story, behavioral patterns, and specific needs of a user group. While a target group analysis only defines the external characteristics, a persona provides insights into the “why” behind the users’ decisions.
Another distinguishing feature is the method of application. Target group analyses are particularly helpful in marketing to evaluate market potential or to target advertising campaigns to a specific demographic group.
They offer a broader perspective and help understand who might potentially be interested in a product. Personas are used more in product development and UX optimization. They enable designers, developers and product managers to put themselves in the shoes of users and simulate concrete use cases.
A practical software development example illustrates the difference. A company developing a new banking app can use a target group analysis to determine that the main users are between 25 and 50 years old and prefer to use online banking. But it is only through a persona like “Thomas, 46, family man, uses online banking, but feels insecure with new technologies” that it becomes clear that the app must offer a particularly understandable user interface and an easily accessible security concept.
The Importance of Personas in Software Development
Software development faces the challenge of combining complex requirements with user-friendly experience. Technically mature applications can be a market failure if they aren’t tailored to the needs of the users. That’s where personas come in. They make it possible to design software specifically for real users instead of developing it past an abstract target group. Some arguments about why you should rely on personas, especially in software development, are summarized in Table 1.
| Advantage | Explanation | Example |
|---|---|---|
| Create a unified user perspective | Software is often developed by different teams with different focuses. Designers, developers, product managers, and testers each have their own priorities. Without a clear user orientation, it is possible that each team has its own idea of the “typical user”. Personas create a common, data-driven foundation so that all stakeholders work towards the same user needs. | A team is developing a health app. While designers prefer a modern, appealing interface, developers focus on performance and product managers focus on monetization. The persona ‘Max, 45, office worker, needs quick and clear functions’ helps all teams to focus on the actual user needs. |
| Help prioritize the right features | There are countless possible features in every software project. But which of those are really important? Personas enable fact-based prioritization: Instead of planning features only from an internal perspective, teams can question them in a targeted manner. Functions that don’t offer added value for the main user groups can be sorted out at an early stage. | A software company is considering if offline mode is necessary for a new note-taking app. The persona ‘Sophie, 28, often works on the go without a stable internet connection’ clearly shows that this feature offers great added value. |
| Improve User Experience | One of the biggest challenges of modern software is intuitive usability. When developers design software from their own perspective, a tool is often created for experts – not for end users. Personas help align design decisions with real-world usage scenarios. They provide information on how users interact with the software, what experience they have and what expectations they have. | An e-commerce platform develops a mobile version. The persona ‘Anna, 32, regularly shops with her smart phone’ shows that large buttons, easy navigation and a fast checkout process are essential. |
| Enable better test scenarios and User Acceptance Tests (UAT) | Software testing often focuses only on technical aspects: Does the application run flawlessly? But other questions are just as important: Is the software understandable for the user? Does it serve its purpose? Personas help define realistic test cases that simulate typical usage processes. This can significantly improve quality assurance by specifically checking for actual user needs. | A team of developers is testing accounting software. The persona ‘George, 50, experienced accountant, often uses export functions’ helps to make test cases realistic and to ensure that the software works in practice. |
| Promote Agile development and user-centered iteration | In Agile processes such as Scrum or Kanban, software is developed and optimized step-by-step. Personas help define user stories more realistically by using them as concrete user profiles for use cases | An Agile team develops a time tracking system. A user story with the persona ‘Tom, 35, project manager, wants to quickly track working hours in the app’ makes it clear that simple time tracking is more important than complex data analysis. |
| Prevent undesirable developments and save costs | Wrong decisions in software development are expensive. Many companies invest months in features that end up being barely used. By using personas, teams can see early on whether a function is relevant at all, before investing time and budget. Personas help interpret user feedback in a targeted manner and avoid unnecessary development cycles. | A company is developing a social media app. Based on the persona ‘Lisa, 21, uses social media every day, but switches apps quickly if they are too complicated’, the team recognizes early on that intuitive operation is crucial. |
| Improve communication between development and stakeholders | Customers, investors and executives often have different ideas about the target group of a software. Personas offer a concrete picture of the users that is understandable to everyone. They help justify decisions to stakeholders by showing which features are being developed for which user groups. | A software provider presents a business solution to an investor. Instead of showing abstract user numbers, he describes the persona ‘David, 40, CFO of a medium-sized company’ to illustrate the software’s importance for financial decision-making processes. |

Psychological Basics: How User Behaviour and Decision-Making Processes Influence Personas
People may use software rationally, but their decisions and behaviour are also shaped by emotions, habits, and unconscious thought patterns. Personas serve to make precisely these psychological mechanisms tangible in order to design a product in such a way that it can be used intuitively, efficiently and pleasantly.
A central aspect is the way people make decisions. Psychologist Daniel Kahneman distinguishes between two systems of thought: a fast, intuitive system and a slow, analytical system. In software development, it is crucial to consider both ways of thinking.
Users expect an application to support their habitual thought patterns so they don’t have to think twice. An example of this is the arrangement of buttons in a mobile banking app. If the “Transfer” function is intuitively placed, it will be used without much thought. However, if it’s hidden in an unfamiliar place, it can cause confusion and frustration. In such cases, personas help simulate typical behaviours and expectations, optimizing user guidance.
Another psychological influencing factor is cognitive load, i.e. the amount of information that a person can process at the same time. Users don’t want to be overwhelmed with unnecessary options and want to find a solution to their problem quickly. A good example of this is a travel provider’s booking platform. A persona like “Anna, 34, plans vacation during her lunch break and has little time” makes it apparent that clear navigation and a quick booking option are essential. If they are overwhelmed with too many choices, they are more likely to abandon the process in frustration.
Emotions also play a central role in interacting with software. An application can convey trust and security or trigger uncertainty and anger. Especially with security-critical applications, like an online banking app, it is important that the user feels in control at all times.
A persona like “Stefan, 55, rarely uses online banking and has concerns about security” helps design functions such as two-factor authentication in such a way that they are understandable and easy to use without overwhelming the user.
In addition, people are not only shaped by their individual experiences, but also by social influences. The need for social validation is evident in apps with community functions. An example of this is a fitness app where users can share their training successes with friends. The persona “Tom, 29, sports enthusiast, is motivated by competition” can help integrate gamification elements into the application in a meaningful way. If this is ignored, the app may lose engagement because users don’t feel sufficiently engaged.
Personas therefore help to incorporate psychological aspects into software development. They make visible how people think, what fears or expectations they have, and how they interact with an application.
Developing Personas: Methods and Data Sources
Personas are only useful when they’re based on sound data. A well-designed persona is more than a fictional character with a name and a stock photo – it represents real user needs, behaviours, and challenges. In order to develop realistic and meaningful personas, a combination of qualitative and quantitative methods and reliable data sources is required.
From data collection to persona creation
The first step to develop personas (Figure 1) is data collection. Companies can draw on various information sources to understand user behaviour and needs. One of the most valuable methods is the direct user survey. Interviews and surveys make it possible to gain deeper insights into the mindset and challenges of users. For example, a software company for a project management app can find out through interviews with team leaders which features really help them in their day-to-day work and which they find annoying.
Figure 1: Process for creating and using personas
In addition, analytics data provides valuable insights into user behaviour. Which functions are frequently used? Where do users abort processes? Heat maps and click analyses can help identify weaknesses in user guidance. For example, users of an e-commerce platform may abandon the purchase process because the checkout is complicated. A persona like “Lisa, 32, frequent online shopper, expects a fast and smooth checkout” can help address these problem areas.
Combining qualitative and quantitative data correctly
Effective persona development requires the combination of quantitative data (such as user statistics and survey results) and qualitative data (such as interviews and observations). While quantitative methods provide insight into what users are doing, qualitative approaches provide insights into why they are doing it.
We can see an example of both methods un the development of an educational platform. A platform analysis shows that many users drop out after a few minutes – a clear signal that there are problems with user guidance.
By interviewing teachers and students, the company learns that most users are overwhelmed because too much information is presented at once. Based on these findings, a persona such as “Max, 17, student, uses the platform irregularly and needs intuitive navigation” can be developed to improve user guidance in a targeted manner.
From raw data to persona
Once enough data has been collected, it’s a matter of transferring it into a tangible persona. A persona should contain concrete, but not too detailed, information to serve as a helpful tool in the development process. In addition to demographic data such as age, occupation, and technical affinity, motivations, frustrations, and typical usage scenarios should be included.
For example, a good persona might look like this:
- Name: Sarah Meier
- Age: 38 years
- Occupation: Marketing manager
- Technical affinity: Experienced in using digital tools, but prefers simple solutions
- Challenges: Too many complex functions in software complicate everyday work
- Motivation: Increased efficiency through intuitive and time-saving tools
This persona can be used as a reference at all development stages to validate design decisions. The goal is not to create as many personas as possible, but to create a few, precisely elaborated profiles that cover the most important user groups.
With a solid methodology and the right data sources, an abstract target group becomes a living persona that helps teams tailor products to the needs of users. This results in technically sophisticated, intuitive software.
Persona Models
Personas are a proven tool of making user groups tangible and better integrating their needs into the development process. But not every persona is the same – depending on the objective, database, and application, there are different models to use in practice. Choosing the right persona model depends on the project’s requirements: Should the persona be as close to reality as possible or offer a simplified representation of user needs (Table 2)?
| Type of Persona | Description | Example |
|---|---|---|
| Fictional Personas – The Classic Approach | The most commonly used personas are based on a mix of real user data and fictitious additions that make the target audience more tangible. They contain demographic information, behaviours, challenges, and goals for each user group. This type of persona is especially useful in the conception phase to ensure that all decisions are aligned with a specific target group. However, there is a risk that hypothetical assumptions will distort reality – which is why it is important to use real user data as a basis. | A software company is developing a new project management tool. A fictitious persona could look like this: Name: David Schröder Age: 42 years Occupation: IT-Project manager Technical affinity: High, uses digital tools daily Challenges: Many simultaneous projects, looking for ways to better organize the team Motivation: Clear overview of deadlines and resources, easy integration with existing systems |
| Data-Driven Personas – The Analytical Approach | These rely on quantitative methods. This is where usage statistics, heatmaps, survey results or AI-supported analyses are used to identify precise patterns in user behaviour. The advantage of this model is its high precision, as it is based on real behavioural data. The disadvantage lies in the potential abstractness: data shows the behaviour, but often not the underlying motives, which should be supplemented by qualitative research. | An e-commerce platform that uses analytics to detect that a large group of users regularly add products to the cart but never complete the purchase. Based on this data, a persona is developed that represents exactly this behaviour: Name: Julia Berger Age: 29 years Occupation: Online shopper with high price awareness Behaviour: Frequently adds products to the cart, but waits for discount promotions Motivation: Wants to shop as cheaply as possible, leaves the site if there are no discounts |
| Extreme Personas – The Innovation Approach | Extreme personas are based on marginal users from the target group, like those with very high or very low technical skills or special usage situations. By specifically considering such extreme users, all user groups can often benefit. Improvements in accessibility or usability benefit visually impaired people and make the app more intuitive overall. | One example is the development of an accessible app for people with visual impairments. An example: Name: Thomas Hoffmann Age: 55 years Occupation: Lawyer Technical affinity: Medium, but regularly uses screen readers Challenge: Many apps are poorly optimized for screen readers, leading to frustration Motivation: Wants to be able to use digital services without restrictions |
Table 2: Types of Personas
Each persona model has its own specific advantages and is suitable for different fields of application.
Data-driven persona development: Using AI, analytics, and user research
Artificial intelligence (AI), data analysis and user research make it possible to build personas not just on assumptions, but on measurable behavioural patterns. This creates data-driven personas that are more dynamic, precise, and flexible.
AI can analyse enormous amounts of user data and recognize patterns that would often be difficult for humans to understand. Machine learning can be used to identify clusters of user types that show similar behaviours. While conventional personas are often based on assumptions, this data-driven persona uses real user data to explain behaviour in a targeted manner and derive possible courses of action.
Besides to AI-supported methods, classic user research continues to play an important role. A/B testing, heatmaps, and user interviews can help better understand behaviours from the data. While pure data analysis often only shows what users are doing, qualitative methods provide the answer to the why.
One example is a learning platform where many users start their courses but don’t finish them. The pure analytics data shows a high bounce rate after the first lesson. But only interviews with users provide the explanation: Many find the learning curve too steep and lose motivation. A data-driven persona could look like this:
- Name: Julia, 29, works and learns in her free time
- Behaviour: Starts courses, but often drops out after a short time
- Challenge: Lack of motivation and time
- Solution: Shorter learning units or gamification elements such as progress rewards
This shows how valuable the combination of data analysis and direct user feedback is. The persona is underpinned by numbers and given an emotional and motivational dimension through qualitative research.
A major advantage of data-driven personas is that they are not static. While classic personas are often created at the beginning of a project and then rarely updated, AI-powered personas can be continuously optimized through real-time data. One example is a music streaming platform that evaluates their user habits. The platform can create and customize dynamic personas based on listening behavior.
If a user suddenly listens to more jazz music, his persona could develop from “Eva, 25, indie rock fan” to “Eva, 25, music discoverer with broad taste”. With this dynamic approach, software solutions can be further personalized. Whether it’s recommendation algorithms, marketing strategies or UX optimization – data-driven personas help companies to better understand users in real time and offer tailor-made solutions.
Using AI, analytics and user research takes persona development to a new level. Instead of relying only on assumptions and individual opinions, data-driven personas enable realistic and dynamic user analysis. The combination of quantitative data analysis and qualitative interviews ensures that personas reflect the behaviour of the users and helps us understand their motivation and challenges.
Difficulties
Although personas are a powerful tool for user-centred development, there are some typical hurdles that can limit their effectiveness. A persona alone does not guarantee better software – its success depends on how it is created, interpreted, and used in the development process. Incorrect or inaccurately used personas can even have a contrary effect, leading to undesirable developments.
One of the most common challenges is that personas are based on guesswork instead of real-world data. If teams develop a persona based solely on internal discussions, without interviewing actual users or analysing usage data, this can lead to bias.
A persona that only reflects one’s own expectations instead of mapping real user needs will quickly lose relevance. An example of this is a software company that develops a project management tool and assumes that all users are highly tech-savvy. If it later turns out that a large part of the target group consists of less tech-smart team leaders who want it to be easy to use, the product could be developed without the needs of real users.
Another problem is creating so many personas that the team loses track. Instead of focusing on a few representative core personas, often many user profiles are created that differ only slightly. This can lead to personas no longer being used as action-relevant tools, but merely existing as overloaded documents.
At the same time, the opposite can also be problematic: overly general personas that are supposed to cover all possible user groups, but in the end do not represent real needs. A persona like “User X, 30-50 years old, interested in technology” is so unspecific that it can hardly serve as a decision-making basis. Effective personas need a clear focus on typical user groups with differentiated characteristics.
Even the best personas are useless if they’re created only once and not actively considered in the development process. Often a lot of energy is invested during creation, but once the day-to-day business dominates, the personas are forgotten.
Personas are not static documents – they should be revised and adapted regularly. User needs, technological trends, and market requirements are constantly changing. If personas remain unchanged for years, they can lose relevance and lead to wrong decisions.
Tools
There are many tools for creating personas that help us better understand and visualize the target groups:
- Make My Persona by HubSpot: An interactive, free tool that walks you through a seven-step process to create detailed buyer personas (Figure 2). At the end, you’ll receive a professionally designed persona document that you can download and share with your team.

Figure 3: Persona Tool: SemRush
These tools help you create detailed and realistic personas that can serve as the foundation for marketing strategies, product development, and user experience design. It’s best to try out a few tools that come closest to your own requirements in terms of functionality and operation. The same applies to persona tools: they should be easy to use and speed up the development process, not create hurdles and ultimately, they should make work fun.
Conclusion
Personas are essential in modern software development. They help user needs become tangible in order to make targeted development decisions and more intuitive and effective software. Unlike traditional audience analytics, which rely on demographic data, personas provide detailed insights into user behaviour, motivation, and challenges. This allows better feature alignment, UX design, and product strategies with actual user needs.
Data-driven personas, especially those which are optimized through continuous analyses, offer an innovative way to keep user profiles dynamic and improve development processes. Despite their many benefits, there are some challenges, especially the risk of outdated, unused, or overly generic personas.
In summary, it’s clear that the targeted use of personas improves the quality of software products and saves time and costs. Companies that effectively integrate personas into their development process benefit from more user-friendly solutions, happier customers, and ultimately greater market success.
