Welcome to software engineering research field!
You possibly have been developing software for years and have just realized that you love it but you want to do something more than just finishing trivial tasks using conventional methods and tools.
Now you want to improve the way you do your challenging tasks. You want to complete them faster and with lower cost. You want to create innovative methods and tools to help other people systematically develop software. If this is true then software engineering research is waiting for you.

- this Ian Sommerville (2016). Software Engineering. 10th Edition. Pearson book or
- this Vaclav Rajlich (2012). Software Engineering: The Current Practice. Chapman and Hall/CRC book first.
Although these books provide you a general view and a big picture of software engineering they do NOT give you every details about all the mentioned topics. Instead they present summaries about the key problems in software engineering and the most popular solutions to those problems.
In other words, these books prepare a background for you so that you could begin to do a software engineering research.
While reading these books you can also review all the topics on this website for detailed information of each topic these books mention.
After that please read this William M.K. Trochim (2006). Research Methods Knowledge Base book to get familiar with research terminologies, types and methods.
In order to begin to do a software engineering research you will need to get the idea of what may be investigated, how to conduct the investigation, what will be produced and how to ensure that what you have found is correct and useful.
It means that you should clarify
- what is your research subject (Is it a laboratory experiment or a real world project?),
- what is your unit of analysis (Is it a a software project or a requirement process or a design process or a testing process or a group of people or a model or a notation or a data structure or an algorithm?),
- what is your research result (Is it a model or a method or a technique or a tool or a notation or an answer or an judgment?)
- what you will do to your research subject and how you can obtain your research result (How do you collect and analyze data? How do you formalize or model or represent the problem? How do you formalize or model or present your solution?),
- which method is used to validate your result (Is it a mathematical proof or a controlled experiment or a case study?)
Please read the following papers to get knowledge about research subjects, research results, data collection and analysis, and research validation.

Then you need to identify an appropriate research problem. This is the most difficult task. When identifying a research problem you should carefully review your background knowledge and your interest, and clarify the basic background that you need to have before conducting a research related to the selected problem.
The easiest way to identify a research problem is to consult with your advisor. Maybe he or she already has a funded research project with various problems that need to be solved.
If you do not have an advisor or your advisor does not have a funded research project then please visit some of the websites below to look for your concrete interested research topics. Hopefully, you can identify some keywords that you are interested in (for example software architecture, microservice architecture or multi-tenancy architecture) after browsing these websites.

After a research topic is identified and selected with some concrete keywords there are 2 approaches for you to look for a research problem.
The first approach is to select a recent paper that you are most interested in. Then read and analyze this paper to answer the following questions:
- What is the problem that the paper tries to address?
- To which real world software systems has the solution proposed by the paper been applied? It is fine that the answer for this question may not be available.
- What are the other primary approaches that have been proposed to solve the same problem posed by the paper?
- How can these solutions be compared to one another?
- Are there any data and source code illustrating the solution that can be used for solution verification and validation?
- What are the remaining issues that the paper has not completely solved?
- Are there any directions for improving the solution? Why? It is fine that the answer for these questions may not be available.
If the selected paper that you have read just poses a general problem (The indicators of this situation are that you cannot answer most of the questions above.) then you may need to conduct a systematic mapping study by:
- Searching for primary studies related to the keywords related to the general problem. Please use the websites below for searching for related works:
- Rigorously defining a classification framework (i.e. What are the categories? How shall problems be categorized?),
- Applying the classification framework to the primary studies (i.e. What are the concrete problems and their corresponding categories),
- Synthesizing the obtained data to produce an overview of the state of the art (which problems were solved, which problems are still unsolved).
The second approach is to look into a software system that you are currently involved in. Then identify the tools (i.e. libraries or frameworks or external systems or architectures or algorithms or notations) and methods related to your selected research topic that have been being used for developing the software system features. Then try identifying which part of these tools and methods is still not perfect and needs to be improved, or what is missing in these tools and methods that makes them difficult or unable to fulfill specific requirements. If you follow this approach then please be noted that
- The research results are the improved tools or methods, NOT the software system that you are developing. These results need to be applied to the software system to evaluate its effectiveness or applicability.
- If the software system that you are involved is trivial or the tasks can be done using the existing solutions without any issues then there may be no business need of improving the tools and methods. Therefore context and motivation examples are critical when identifying a relevant problem.
- You need to ensure that these results have not been produced before or these results are not published for community, and your results bring benefits not just to yourself but also to community. This should be stated clearly in the context and motivation examples.
- You need to be careful about intellectual properties because most reviewers of your research results may need access to the source code of your software system to evaluate your contribution.
Hopefully, at this point you will have spotted an unsolved problem that you are interested in.
Then please iteratively
- Identify research questions related to the problem.
- Build your background knowledge related to the problem and research questions.
- Check the literature for existing solutions.
- Search for tools and methods related to the problem and research questions.
- Conduct the study by proposing your solution to the problem (i.e. providing your answers to the research questions). You can(i) apply an existing tool or method to a system in a specific context, and collect evidences to prove that the problem can be solved using the tool or method (applied research, validation research), for this approach, you need to ensure that this study has never been conducted by someone else, and your result brings benefits to community, or(ii) implement a software system based on an existing tool or method to help others use the tool or method more effectively (applied research), for this approach, you need to clearly clarify the benefits when applying the tool or method by using your software system, or
(iii) apply two existing tools or methods to develop the same software system, and collect evidences to help others to select the better one in a specific context (applied research), or
(iv) extend an existing tool or method to address some of its disadvantages (theoretical research), or
(v) build a novel tool or method to solve a problem (theoretical research).
Regardless the selected approach, you need clearly clarify a real business need of your research result.
- Document your solution.
- Soberly and critically evaluate the effectiveness (i.e. the cost, the time, the fix) of your solution by comparing it with the existing solutions or baselines using benchmark inputs or prove the correctness of your solution using mathematical modeling and logical reasoning.
Hope that you will have found a research problem, solved it, finished documenting and evaluating your solution. Then you will need to write your paper. Your paper must
- Clearly articulate the topic of research,
- Summarize the critical problems and current solutions used in the field,
- Describe the proposed research concepts that constitute your solution, the intended methodology, the evaluation strategy, and results to date, and
- Identify the contributions of the proposed work.
