Two papers cited, for research software and data management plans

These are important aspects that are highly relevant to Maneage: its
philosophy (the former) and usability (the latter). To add them, I tried to
summarize some other parts of the paper.

 Due to the complexity of modern data analysis, a small deviation in the final result can be due to many different steps, which may be significant for its interpretation.
-Publishing the \emph{complete} set of operations is the only way to avoid ambiguity and wasting resources.
+Integrity checks are a critical component of the scientific method, but are only possible with access to the data \emph{and} its lineage (workflows).
 For example, \citet{smart18} describes how a 7-year old conflict in theoretical condensed matter physics was only identified after the relative codes were shared.
 \citet{miller06} found a mistaken column flipping in a project's workflow, leading to the retraction of 5 papers in major journals, including \emph{Science}.
 \citet{baggerly09} highlighted the inadequate narrative description of the analysis and showed the prevalence of simple errors in published results, ultimately calling their work ``\emph{forensic bioinformatics}''.

 The completeness of a project's published workflow (usually within the ``Methods'' section) can be measured by the ability to reproduce the result without needing to contact the authors.
 Several studies have attempted to answer this with different levels of detail. For example, \citet{allen18} found that roughly half of the papers in astrophysics do not even mention the names of any analysis software, while \citet{menke20} found this fraction has greatly improved in medical/biological field and is currently above $80\%$.
 \citet{ioannidis2009} attempted to reproduce 18 published results by two independent groups, but fully succeeded in only 2 of them and partially in 6.
