This process ensures that research addresses genuine engineering challenges rather than simply repeating existing knowledge.
A strong understanding of research gaps enables electrical QA/QC researchers to develop focused research questions that contribute to improved quality management practices. By investigating unresolved issues related to digital technologies, sustainability, testing methods, and emerging engineering challenges, researchers can support innovation, enhance system reliability, improve safety performance, and contribute valuable knowledge to the future development of electrical engineering quality management.
4. Evaluate How the Proposed Research Project Will Address the Identified Gaps in Current QA/QC Knowledge
A successful electrical Quality Assurance and Quality Control (QA/QC) research project must demonstrate how it will contribute to solving existing knowledge gaps, improving current practices, and developing new understanding within the field of electrical engineering. Identifying research gaps is only the beginning of the research process; the next critical step is evaluating how the proposed investigation will address those gaps through structured analysis, evidence collection, and the development of practical solutions.
In advanced electrical QA/QC research, a project should not only describe existing problems but also explain how its findings will contribute to improved quality management outcomes. The ability to evaluate research contribution requires a clear understanding of the relationship between existing limitations and the proposed research approach. Researchers must demonstrate that their investigation has the potential to provide new evidence, improve current processes, evaluate emerging technologies, or develop strategies that enhance electrical quality performance.
Electrical engineering projects are becoming increasingly complex due to digital transformation, renewable energy integration, advanced monitoring systems, automation, and higher expectations for reliability and sustainability. These developments create new challenges that traditional QA/QC approaches may not fully address. Therefore, research projects must be designed to investigate unresolved issues and provide evidence-based improvements that are relevant to modern engineering environments.
Evaluating the contribution of a proposed research project involves analysing how effectively the research objectives, methodology, and expected outcomes align with identified gaps. A strong research project should clearly demonstrate what knowledge is missing, why the gap is important, and how the investigation will generate valuable findings for industry and academic development.
Understanding the Relationship Between Research Gaps and Project Contribution
A research gap represents an area where existing knowledge is incomplete, limited, inconsistent, or unable to fully address current challenges. A proposed research project should directly connect with these gaps by developing methods to investigate and resolve them.
The relationship between research gaps and research contribution can be explained as:
Existing Knowledge

Identified Limitation
↓
Research Gap

Improved QA/QC Practice
For example, previous studies may identify that digital QA/QC systems improve documentation efficiency but provide limited evidence about their effectiveness in reducing electrical installation defects. A proposed research project could address this gap by evaluating how digital inspection platforms influence defect detection and quality performance.
