A '''bioinformatics workflow management system''' is a specialized form of [[workflow management system]] designed specifically to compose and execute a series of computational or data manipulation steps, or a [[workflows|workflow]], that relate to [[bioinformatics]].

There are currently many different workflow systems. Some have been developed more generally as [[scientific workflow system]]s for use by scientists from many different disciplines like [[astronomy]] and [[earth science]]. All such systems are based on an abstract representation of how a computation proceeds in the form of a directed graph, where each node represents a task to be executed and edges represent either data flow or execution dependencies between different tasks. Each system typically provides visual front-end allowing the user to build and modify complex applications with little or no programming expertise.<ref>{{Cite journal | last1 = Oinn | first1 = T. | last2 = Greenwood | first2 = M. | last3 = Addis | first3 = M. | last4 = Alpdemir | first4 = M.

==Comparisons between workflow systems==

With a large number of bioinformatics workflow systems to choose from, it becomes difficult to understand and compare the features of the different workflow systems. There has been little work conducted in evaluating and comparing the systems from a bioinformatician's perspective, especially when it comes to comparing the data types they can deal with, the in-built functionalities that are provided to the user or even their performance or usability. Examples of existing comparisons include

* The paper "Scientific workflow systems-can one size fit all?",<ref>{{Cite doijournal | last1 = Curcin | first1 = V. | last2 = Ghanem | first2 = M. | title = Scientific workflow systems - can one size fit all? | doi = 10.1109/CIBEC.2008.4786077 | pages = 1–9 | year = 2008 | pmid = |noedit pmc = }}</ref> which provides a high-level framework for comparing workflow systems based on their control flow and data flow properties. The systems compared include [[Discovery Net]], [[Taverna workbench|Taverna]], Triana, [[Kepler scientific workflow system|Kepler]] as well as Yawl and [[Business Process Execution Language|BPEL]].
