    4. 4. Just the Nature of the problem?<br />No one starts writing software intending<br /> to abandon it completely and yet sustainability – developing and maintaining over a long period – is a problem for scientific software <br />Statistics courtesy of Greg Wilson, Software Carpentry, from Nature article<br />Published online 13 October 2010 | Nature 467, 775-777 (2010) <br />doi:10.1038/467775a<br />
    5. 5. What is needed<br />Effort, support and guidance to ensure that researchers can continue to use their chosen software as a cornerstone of their research<br /><ul><li>And beyond the lifetime of its original funding cycle</li></ul>The lifetime of a software code is now greater than that of hardware<br />Software is the capital investment, hardware is the consumable?<br />UK funding organisations want to ensure investment in software is not wasted<br />Similar efforts in the USA: NSF SI2 initiative and Australia<br />Situation in Japan?<br />

    35. 35. Software sustainability is part of the process<br />Comparable to risk management<br />No one right “solution” but many examples of best practice and process<br />Plan from before the start if possible<br />But must be reviewed regularly<br />No longer considering timescales bounded by a project, but considering the product<br />
    36. 36. The Software Maturity Curve<br />Portals<br />Quantum<br />chemistry<br />Cloud<br />Computing<br />RDBMS<br />Social<br />Simulation<br />Workflows<br />Spatio-<br />Temporal<br />viz<br />Molecular<br />Dynamics<br />Geospatial<br />viz<br />Digitised<br />Doc Analysis<br />Digital<br />repositories<br />Software proliferation<br />Innovation<br />Consolidation<br />Customisation<br />Time<br />
    37. 37. Enabling Innovation<br />Supporting emergent disciplines<br />Needs recognition of innovative software development as part of funding <br />Breaking down barriers<br />We cannot assume that the way people interact with resources will conform to expectations<br />e.g. researchers will use/store files outside of universities<br />Researchers will do whatever they can to get an edge – they will not always conform<br />
    38. 38. Supporting Consolidation<br />“e-Science is an organic, emergent process requiring ongoing, coordinated investment from multiple funders and coordinated action by multiple research and infrastructure communities. It is both an enabler of research and an object of research” – RCUK Review of e-Science<br />Bridging the expectation gaps between participants<br />Maintenance vs. research<br />Different timescales for “exciting” work<br />Well supported open platforms are the key in the age of the research mashup<br />Platforms to enable bottom-up innovation<br />Platforms to enable citizen participation<br />Competition/innovation built on top c.f. industry <br />
    39. 39. Sustaining Customisation<br />“The time constants for real transformative impact and significant competitive advantage is decades” – RCUK Review of e-Science<br />Sustain software infrastructure in the long term<br />Differing models: through centres; within institutions; distributed<br />Need to change perceptions so that software is seen as valuable! (and not just invaluable)<br />Lower barriers to community growth and participation<br />Increase value of providing services<br />Virtually merge + map small amounts of effort / funding<br />
    40. 40. Invest in people<br />People are the most important investment<br />Adaptability, ability to recognise transferable skills, not strict career paths<br />Software developers come from many backgrounds <br />If e-Science is multi-disciplinary, multi-institution, multi-scale then make it easier to recognise peoples efforts as they move<br />University structures do not make it easy<br />These people are key to effective e-Science as they bridge the gap between other participants<br />
    41. 41. The credit question<br />How do we get credit for reusing, extending and sustaining software?<br />Research credit is based on publication output<br />Data citations and credit for reuse are still not commonplace<br />Software credit is the next stage<br />Otherwise how can we persuade people to contribute back?<br />This is a question which must be answered at an international level<br />
