Downing Street has released a series of documents that show the government has failed to meet its own self-imposed deadlines on the cancellation of troubled projects.

Whitehall is also behind on setting open standards for technology, as well as improving procurement, according to the documents.

The news comes as the government said it had begun work to create a real time tax and national insurance system.

In a series of structural reform plan updates from different departments – published by Number 10 as part of ‘transparency’ efforts – the Cabinet Office said it had not succeeded in decommissioning a first tranche of IT projects, because it was still trying to agree on what should be terminated or rescoped.

The government had planned to complete the review and cancel the first tranche of projects by the end of January. Work is ongoing.

Additionally, the government has failed to meet its 31 January deadline for setting open standards and IT procurement rules, including how 'skunk works' (autonomous innovation groups) will contribute to buying. But it insisted “strong progress” had been made, and that a skunk works team was in place.

The government has also failed to publish central government contracts worth over £10,000, however it plans to do so on the new Contract Finder website launching at the end of the week.

The Home Office has still not completed work, originally under a December deadline, to publish controversial proposals for the storage of internet and email records. This was because of work on a counter terrorism review, it said.

In terms of new work, the government has begun reviewing websites for decommissioning as part of cost savings. By March, it expects to issue a full plan for creating shared services in Whitehall, and will also publish a plan for improving access to the public sector market for small to medium sized IT suppliers.

HM Revenue and Customs, by the end of April 2012, plans to implement real time technology infrastructure for tax and national insurance, after a consultation on the new systems closes this month. By March 2013, the Department for Work and Pensions expects to have completely joined the systems to aid its own benefits reform.

In other areas, the Department of Health plans to distribute funding to strategic health authorities within three months to support information sharing, and the Department of Energy and Climate Change will develop a plan for smart metering in the same timeframe.

The Department for Communities and Local Government within 14 months will publish a list of data requirements for local councils. Meanwhile, the Department for Business, Innovation and Skills will create a network of advanced technology centres before April next year, and within six months from now it will build a website for entrepreneurial information, and co-locate HMRC and Companies House online transaction services.

This month, as work proceeds on the UK Space Agency, BIS will also develop a strategy for how the country will stimulate trade with hi-tech sectors.
