The literature review identified two classes of challenges for testing scientific software. First, the characteristics of the software result in challenges to 1 test case development, 2 identifying expected outputs, 3 test case execution, and 4 interpretation of results. Second, the cultural differences between scientists and the traditional software engineering community result in challenge because of limited understanding of 1 testing concepts, 2 testing process, and 3 how to apply testing methods.

The literature also described the following techniques for overcoming these challenges: pseudo oracles, analytical solutions, experimental results, measurement values, simplified data, and professional judgement. The authors claim that software engineering research can provide effective solutions for testing software with oracle problems. However, almost all of these scientific software developers are self-taught.
Therefore they typically do not employ many basic software development practices such as version control, issue tracking, writing maintainable code, and task automation. These practices have proven effective in many research settings.
We analyzed five cancelled software engineering projects. One case was an What happens before a project starts? Springer , Before an outsourced software project officially begins the contracting or supplier organization has already expended effort. Although project start and start-up effort impact on project success in most cases these are Savolainen, Paula Springer-Verlag , A definition of a project success includes at least three criteria: 1 meeting planning goals, 2 customer benefits, and 3 supplier benefits.
This study aims to point out the importance of the definition of the project Inefficient product derivation practices can greatly diminish the productivity gains expected from a software product line approach.
Evidence-Based Software Engineering and Systematic Reviews
As a foundation for systematic and efficient product derivation a better understanding Login Register. PubMed output files. The most common file type is RIS. This is problematic in interdisciplinary studies when importing studies from a wide range of sources and grey literature databases, many of which do not provide standardised export features e.
Automated import of abstracts and full-text PDFs is also an important time-saving feature in larger studies, but is not yet widely available and is difficult when many studies are not open access, as in the field of conservation biology. There is increasing demand for information management systems which assist with the centralisation and management of the systematic review process, to improve efficiency and to facilitate teams of reviewers to collaborate. We have identified 22 software packages which provide this functionality, designed for users from a wide range of disciplines.
There is a large degree of overlap between many of these software packages, however most have been developed with particular disciplines in mind and lack the customisability suitable for access and use by reviewers across disciplines.

As a general observation, many developers appear to have developed these tools without an awareness of the full range of similar tools available a point also noted in a recent systematic review [ 27 ]. CADIMA also offers greater security than traditional approaches to review management, such as Microsoft Excel, when it comes to sorting records and tracing included articles between different stages of the screening and data extraction process.
The ability to export files and work offline easily with CADIMA was considered a great asset, although the linear structure of the application has so far precluded adjustments to review team membership between screening stages. The developers have taken this into consideration for future developments of the programme. As CADIMA combines many different stages of the review process in a single piece of software, it also has the advantage of enhancing transparency and replicability.
CADIMA is designed to provide important information to users in the form of prompts, which make the difference between a rigorous systematic review and a standard literature review, considerably reducing the barrier to entry for first time reviewers. These include protocol development prompts which mirror Collaboration for Environmental Evidence guidelines, and stages such as consistency checking.
The structure and layout of CADIMA encourages users to document their methodology and screening criteria clearly, and also provides a location for record and methods to be hosted online, so that subsequent revisions can be undertaken easily. Like CADIMA, the majority of software packages support teams of reviewers, require no prior coding knowledge and offer a range of help and support, facilitating rapid learning and working with a team of individuals with differing degrees of experience.
A handful of tools are particularly designed to lead the user in a stepwise manner through the review process, including CADIMA with its inbuilt guidance and clear layout, and SESRA [ 29 ], which mirrors the stages in the Kitchenham and Charters guidelines [ 5 ].
Others, such as EPPI-Reviewer, do not follow this structured approach, and users design the stages according to their needs, meaning they must be familiar with both the software and systematic review methodology. No single software package guides the reviewer through all stages of a systematic review or map project from question formation to the exporting of project documentation , meaning stages such as literature searches or analysis and writing up of results are often expected to be managed separately.
The principal advantage of using software to assist in managing the review process is to increase efficiency of time consuming tasks, to allow for efforts to be concentrated on the most important tasks—namely synthesis and analysis. CADIMA facilitates the importing and exporting of the results of searching and synthesis to allow literature searches and statistical analysis to be conducted flexibly, using alternative software, and focuses on simplifying the tracking large numbers of review articles throughout the process.
Based on the results of the conducted review and received user feedback, the following issues will be considered during the next round of development for CADIMA:. This can be quite time consuming in cases where many duplicates are identified. Currently, the same reviewers have to participate during the study selection process at title, abstract and full text stage.
In the future, the possibility will be provided that different reviewers can be involved during the respective stages; and. Due to the limitations associated with the conduct of a full systematic review, further evidence synthesis approaches, such as rapid reviews, are evolving in order to save resources and to provide a timely answer to a posed question [ 26 , 30 ].
This is especially important in the political context where time is a major consideration. A future goal for CADIMA is to allow people to customise their review, depending on the purpose of the synthesis and available resources. CADIMA will continue to be developed to join several other software packages which make use of machine learning approaches to increase efficiency at the article screening stages of the systematic review process. This is an area that we believe will be of increasing interest to users, particularly for updating existing reviews algorithms can be trained to identify relevant studies based on similarity to previously included studies [ 31 ] and dealing with very large bodies of literature.
The use of new technology to assist the systematic review process is a rapidly developing area, demonstrated by the inclusion of three new or upgraded software packages expected to become live in in our review plus another we were unable to find further information on; DRAGON ONLINE. Several other packages which came up in our search have been discontinued, suggesting security of funding, ongoing maintenance and continual improvement are essential considerations for the developers of these types of software packages to prevent them quickly becoming obsolete.
From a user perspective, we believe that CADIMA stands out in terms of ease of use, support for multiple users, support for on- or off-line data extraction, commitment to ongoing maintenance and financing, therefore meeting the criteria rated as most important by users of systematic review software in a recent study [ 25 ].
Many other free software packages require prior experience of software development and computer coding, or have limited capacity for ongoing maintenance. Aside from CADIMA, those that are continually updated and provide user-friendly graphical user interfaces, tend to be expensive for team reviews, making them less feasible options for small research teams or non-profit organisations.
