Rationale for the Study
The rationale for the study (also called research justification or purpose of the study) explains why the research is worth conducting. It demonstrates the academic, practical, and personal significance of the study by showing how it contributes to existing knowledge, addresses a real-world problem, or supports the researcher’s professional development.

Research rationale at a glance
What is Research Rationale?
Research rationale refers to the justification for conducting a study. It explains why the research topic is important and why the study deserves academic attention.
A strong rationale answers several important questions:
- Why is this topic worth investigating?
- What gap does the study address?
- What practical value will the findings create?
- How does the study contribute to existing knowledge?
The rationale acts as a bridge between the research problem and the research objectives. It helps readers understand why the study is necessary and what value it is expected to generate.
Importantly, a strong rationale goes beyond personal interest. Simply stating that a topic is interesting is insufficient. Academic justification requires evidence of contribution, relevance, and significance.
Why Research Rationale Matters
The rationale is one of the most important sections of a dissertation because it explains the purpose and value of the entire study.
Without a clear rationale, readers may question:
- the importance of the research topic
- the relevance of the research objectives
- the originality of the study
- the contribution of the findings
A well-developed rationale demonstrates that the research is not being conducted merely for academic completion, but because it addresses a meaningful issue or contributes to knowledge in a valuable way.

Main Sources of Research Justification
Research rationale is typically built around three broad forms of contribution:
| Source of Justification | Main Focus |
|---|---|
| Academic contribution | Addressing a literature gap or limitation |
| Practical contribution | Solving a business or societal problem |
| Personal contribution | Supporting researcher development |
| Methodological contribution | Applying new methods or approaches |
| Contextual contribution | Examining a topic in a new setting |
Many strong dissertations combine several of these forms of justification simultaneously.
Literature Gap as a Source of Rationale
One of the most common ways to justify a study is by identifying a gap in existing literature.
Researchers are expected to contribute something new rather than simply repeating previous studies. This does not necessarily require inventing an entirely new topic. Instead, contribution can be achieved by extending, refining, or re-examining existing knowledge.
Literature gaps often arise because:
- a topic has received limited academic attention
- previous studies used weak methodologies
- findings are inconsistent or contradictory
- the context has changed significantly
- new technologies or business practices have emerged
For example, while employee motivation has been researched extensively for decades, new questions continue to emerge regarding employee motivation in remote working environments, hybrid workplaces, and AI-assisted organisations.
Researchers may also identify a range of limitations in previous studies:
- Methodological Limitations. Previous studies may have used inappropriate research designs, inadequate sample sizes, weak measurement instruments, or unsuitable analytical techniques.
- Contextual Limitations. Research findings obtained in one country, industry, or period may not be applicable in different environments.
- Conceptual Limitations. Previous studies may rely heavily on specific theories, models, or assumptions that deserve re-examination.
When identifying limitations in previous research, it is important to explain how the current study addresses those weaknesses.
Practical Problem as a Source of Rationale
Research can also be justified by its ability to solve a practical problem. Applied business research frequently aims to improve organisational performance, support managerial decision-making, or address industry challenges.
Examples include:
- reducing employee turnover
- improving customer satisfaction
- strengthening brand image
- increasing employee motivation
- improving supply chain performance
- enhancing digital transformation initiatives
For example, a dissertation examining effective succession planning practices within Microsoft may provide practical recommendations that improve organisational leadership continuity. Similarly, a study exploring how artificial intelligence influences consumer purchasing decisions may help businesses improve their marketing strategies.
In these situations, the rationale should clearly explain:
- the nature of the problem
- who is affected by the problem
- why the problem matters
- how the study may contribute to a solution
Not all dissertations need to solve a practical problem. Some studies are primarily theoretical and focus on extending knowledge rather than providing direct organisational recommendations.
Professional Development as a Source of Rationale
Research can also be justified through its contribution to the researcher’s professional development. Many students choose dissertation topics that align with their long-term career objectives, professional interests, or future areas of specialisation.
For example:
- an aspiring HR manager may study employee engagement
- a future marketing specialist may examine consumer behaviour
- an entrepreneur may explore innovation management
- an aspiring consultant may investigate organisational change
Including a professional development rationale demonstrates personal commitment to the research topic and highlights the relevance of the study to future career aspirations. However, professional development should normally supplement academic and practical justifications rather than replace them.
Common Mistakes
Many students write rationales that are too broad and generic. Statements such as “this topic is important” or “many organisations face this issue” provide little academic justification unless supported by evidence. Another weakness occurs when researchers identify literature gaps without clearly explaining how their study addresses those gaps.
Some dissertations focus exclusively on personal interest while neglecting academic and practical contributions. Examiners generally expect stronger scholarly justification than personal preference alone. A further problem arises when the rationale simply repeats the research objectives rather than explaining why those objectives are important.
Research Rationale in the Age of AI and Digital Research
The emergence of artificial intelligence, digital transformation, and rapidly evolving business environments has increased the importance of strong research justification. AI-generated content and automated research tools have made information more accessible than ever, but they have also increased the need for genuinely original and meaningful research contributions. Researchers are increasingly expected to demonstrate not only that a topic is interesting, but also why it remains relevant despite the availability of vast amounts of existing information.
Many contemporary research rationales now emerge from technological change itself. New phenomena such as generative AI, algorithmic decision-making, digital platforms, remote work technologies, and data-driven business models are creating fresh research opportunities and exposing limitations in existing theories. Consequently, researchers must carefully explain how their studies contribute new insights within rapidly changing business environments while distinguishing their work from information that can already be generated or summarised by AI systems.

How to Write a Strong Research Rationale
An effective rationale usually follows a logical sequence.
First, explain the broader research area and establish its importance.
Second, identify a gap, limitation, inconsistency, or unresolved issue within existing literature or practice.
Third, explain how the current study addresses that issue.
Finally, discuss the academic, practical, and professional contributions expected from the research.
The strongest rationales combine originality, relevance, and contribution while maintaining a clear connection with the research objectives.
Example of Research Rationale
Suppose a dissertation investigates the impact of AI-powered recruitment systems on hiring decisions within multinational organisations.
A strong rationale could state that although artificial intelligence is increasingly used in recruitment, existing studies have focused mainly on technological efficiency rather than candidate perceptions and fairness concerns. Furthermore, limited research has explored these issues within multinational organisational settings. The study therefore addresses an important literature gap while also providing practical insights for organisations seeking to implement AI-assisted recruitment processes responsibly.
Exam Tip
Many dissertation proposals lose marks because the rationale focuses on describing the topic rather than justifying the study. Examiners are usually less interested in what the topic is and more interested in why the topic deserves investigation. Always make the contribution of the study explicit and clearly connect the rationale to your research objectives.
