GDS misbriefing

The invitation to tender for the Government Digital Service (GDS) market research contract with IFF Research Ltd includes this picture of the "new identity assurance model":
The document was created on 8 November 2012, according to its Microsoft Word properties, and was last modified on 12 November 2012. Next day, 13 November 2012, the names of the UK's appointed identity providers (the electronic Mary Poppinses) were announced. Halifax weren't on the list. Neither were Lambeth and Visa. Nor Lloyds and Equifax.

Which means that GDS briefed the prospective suppliers wrongly in their invitation to tender.

Experienced consultants like IFF Research will be quite used to that. It always takes a while for the client's real requirements to come to light. By now they will have established a more accurate picture, with seven known identity providers and a mystery one:
How will the interviews go, as IFF Research set about their market research?

IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using Visa as an identity provider?
PITS: yes.
IFF: well they're not on the list. How about Cassidian?


IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using Ingeus as an identity provider?
PITS: are you sure that's how it's pronounced?
IFF: shall I put you down as a don't-know?


IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using Mydex as an identity provider?
PITS: why's it called Mydex? What does it mean?
IFF: I have no idea, the question is would you feel comfortable ...
PITS: any particular reason why I should trust them?
IFF: I ask the questions.


IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using Verizon as an identity provider?
PITS: I thought they were a US mobile phone network.
IFF: they are.
PITS: so how are they going to verify my identity for the UK government?
IFF: I don't know.


IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using a completely unknown supplier represented on this picture by a yellow question mark as an identity provider?
PITS: yes.
IFF: thank you.


IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using digidentity as an identity provider?
PITS: is this a wind-up?
IFF: thank you.

IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using the Post Office as an identity provider?
PITS: the Post Office isn't a private sector supplier.
IFF: Yes it is, look it up on the Companies House website, company number 02154540.
PITS: you mean I can buy shares in it?
IFF: no, the shares in the Post Office are all held by Royal Mail and the shares in Royal Mail are all held by Vince Cable and he's not selling any but otherwise it's a private sector company.
PITS: who's paying for all this identity-providing lark?
IFF: the Department for Work and Pensions, to get Universal Credit going.
PITS: so there's nothing private sector about this at all, is there?
IFF: no, you're right, the private sector element is one of GDS's many fantasies.
PITS: pleasure talking to you, I'm sure, can't wait to see your report.
IFF: don't hold your breath.


IFF: (to person in the street) The government is trying to cause an ecosystem of private sector suppliers to flourish. Would you feel comfortable using Experian as an identity provider?
PITS: yes.
IFF: why? What's the matter with you?
PITS: that's a job they already do, isn't it, they've already demonstrated their competence, unlike any of the other suppliers on your picture.
IFF: is that true?


Why did all the banks and credit card companies refuse to become official identity providers? Why aren't there any UK mobile phone companies among their number? How long will this farce be allowed to continue? How much will it cost us? Will anyone be accountable?

Jo Swinson on midata – How and Which?

Ms Swinson can plead ignorance. Which? can't.

Writing successful publicity material is hard. Quite beyond DMossesq. And, it seems, Jo Swinson, minister of state at the Department for Business Innovation and Skills (BIS). Here she is, trying to write with unfeigned enthusiasm about midata:
Recently I was chatting to the owner of an independent bookshop, who told me animatedly about his Christmas recommendations. In particular which ones I might enjoy most given what other books I had recently read and loved.

How great, I thought, to have that personal, tailored advice, and wouldn’t it be great if I could get that everywhere else?
That gem appears on the blog run by Which? magazine and you can see why the consumer champion Which? wants a disclaimer at the bottom of Ms Swinson's post:
Which? Conversation provides guest spots to external contributors. This is from Jo Swinson MP. All opinions expressed here are Jo’s own, not necessarily those of Which?
The benefits of midata that Ms Swinson manages to name are all available already without midata and have been for decades – BIS's initiative is otiose. The other benefits are vague, unnamed and hypothetical – unreliable, in other words, dubious marketing.

And Ms Swinson fails to warn her readers how these mysterious benefits will be earned. By storing all our personal data on the web with a third party we have no reason to trust. She doesn't tell us that. Standard behaviour for a politician, perhaps, but well below the standards for openness expected of Which?.

Is a disclaimer enough, though? The headline on the post is under Which?'s control and reads What if companies gave me control of my data?. midata offers consumers no control over their data that we don't already have. Its advocates keep promising control. But they can never answer the question how midata will confer additional control. It won't. Because it can't.

But Which? are in deeper than a misleading headline. BIS's 3 November 2011 press release lists the organisations which support midata, including Which?. It will take more than a disclaimer to undo the reputational damage that will follow when consumers discover how midata works. Ms Swinson can plead ignorance. Which? can't.

GDS's identity assurance story continues to unravel

The Potential Provider shall complete Phase 1 by 31 December 2012
DWP, the Department for Work and Pensions, is by far the biggest spender in government, having clocked up £242.3 billion in 2011-12, see HM Treasury's Public Spending Statistics July 2012 (p.53), including £93 billion on pensions.

On 1 March 2012 GDS, the Government Digital Service, wrote: "Today the cross-Government Identity Assurance programme sanctioned DWP to publish a tender to procure Identity services for all of Government", see Identity: One small step for all of Government.

Sanctioned?

Somehow DWP put up with this condescension. GDS would be well-advised not to try it on with our next biggest spender, the Department of Health, £121.3 billion.

GDS went on in their blog post of last March to refer to the procurement of identity assurance services, needed by DWP for their Universal Credit initiative: "The initial DWP services will be required to provide identity assurance for approximately 21 000 000 claimants ... To support the rollout of universal credit and personal independence payments, identity assurance suppliers will be selected in summer 2012 and systems will need to be fully operational from spring 2013".

Let's say that GDS mean that identity assurance services "will need to be fully operational" on or before 22 June 2013.

Question – how did GDS come up with that timetable?

Before you answer, consider – there must have been some reasoning behind GDS's choice of date. They must have had some idea which suppliers will be involved and how they will satisfy DWP's needs.

Yesterday, 10 December 2012, GDS published the details of an identity assurance contract they put out for tender and which they have now awarded. This contract is for qualitative research into the way people could use multiple identity providers to access public services.

Almost every sentence in GDS's invitation to tender (ITT) is contentious. But let's content ourselves with just one, para.4.2.4, the opening sentence of this post: "The Potential Provider shall complete Phase 1 by 31 December 2012".

This is fundamental research for the Identity Assurance Programme. It won't be finished until 31 December 2012. GDS have the option to extend it by up to three months. 31 March 2013. And then there's Phase 2.

The chances of DWP getting its identity assurance services before 22 June 2013? Nil.

GDS's ITT wasn't even completed until 12 November 2012, eight months after they sanctioned DWP's ITT. GDS must have known then that their timetable is a fantasy.

Meanwhile there are 21 million potential claimants out there, waiting for GDS, whose priorities are clearly elsewhere.

If anybody asks you what "misfeasance" means, misfeasance in Whitehall, just point them at GDS.

Universal Credit – GDS's part in its downfall

The importance of IDAP
If public services are to become digital-by-default the Government Digital Service (GDS) need to deliver on identity assurance.

It's their responsibility:
  • Ex-Guardian man Mike Bracken, the Chief Executive of GDS, is also the senior responsible officer owner for Her Majesty's Government's Identity Assurance Programme (IDAP).
  • GDS acknowledge an IDAP project on their blog.
  • And they said on 1 March 2012 that they want to ensure that "... ultimately, HMG-wide Identity Assurance is supplied across central departments via a common procurement portal ... and governed by the Cabinet Office [i.e. by GDS]".
And without IDAP, they say, people who want to use public services will not be able to assert their identities on-line and there will be no digital-by-default:
  • Francis Maude, Cabinet Office Minister, talking about digital-by-default on 6 March 2012: "... for all this to work users of digital public services need to be able to assert their identities safely, securely and simply".
How's it going? What progress is there on IDAP?

IDAP has a customer ...
The first guinea pig has been chosen. The Department for Work and Pensions (DWP) are responsible for Universal Credit (UC) and UC will be the first public service to use IDAP, c.f. Francis Maude again: "... soon Identity Assurance Services will be used to support the Department for Work and Pension’s Universal Credit scheme and the Personal Independence payment which, from 2013, will replace the complex and outdated benefit system".

No IDAP, no UC.

What's involved?

... and IDAP has seven suppliers ...
According to the 1 March 2012 notice placed in the Official Journal of the European Union (OJEU): "The initial DWP services will be required to provide identity assurance for approximately 21 000 000 claimants ... To support the rollout of universal credit and personal independence payments, identity assurance suppliers will be selected in summer 2012 and systems will need to be fully operational from spring 2013".

Two deadlines came and went. 30 September 2012 and 22 October 2012. In the end, it was 13 November 2012 when DWP announced the names of seven "identity assurance suppliers". That's what they were called in the March OJEU notice but, by November, they had become "identity providers" (IDPs).

There were meant to be eight of them but the identity of the reluctant eighth IDP remains a mystery.

Not that the other seven are exactly well-known in the UK – the Post Office, Cassidian, Digidentity, Experian, Ingeus, Mydex, and Verizon – apart from the Post Office, of course, but no-one thinks of that venerable institution as an IDP.

And they're a strange collection. Just look who isn't there. Where are the banks? Where are the (UK) telcos? What happened to the utility companies and the insurance people? Too sensible to accept the hospital pass?

For the first time in history, the UK has official identity providers. You think you already have an identity? Not if it hasn't been provided by an IDP, you don't, not if GDS have their way, not in their modernised, joined up, transformational UK.

As yet, we know nothing about what these IDPs will do – how will IDAP work?

... but the bit in between is missing – there is no IDAP service
It should be big news but the media haven't paid much attention and DWP haven't mentioned IDPs since their 13 November 2012 press release. We have no idea from them how IDAP is meant to work.

Mydex blogged about it but there's been no publicity from the other six named IDPs.

And GDS, the people in charge, have managed just one reference to the appointment of the IDPs, "... we now have a group of suppliers with whom we can work out the practical issues of becoming operational as Identity Providers across all of government".

GDS haven't worked out the "practical issues" yet? It's two years since the prospective suppliers went off to work out the details of what was then the Digital Delivery Identity Assurance Project, part of the G-Digital Programme. Haven't they worked anything out in the interim? What was in GDS's invitation to tender? How do you choose and appoint suppliers if you don't know what you want them to do?

The IDPs are only getting an 18-month contract. And they have to register 21 million claimants for no more than £25 million and issue them all with electronic IDs. How are they going to do that? When are they going to do that? And where?

Remember, OJEU notice: "systems will need to be fully operational from spring 2013". That wouldn't be feasible, not now, December 2012, not even if the details of IDAP had all been worked out but they haven't been ("we now have a group of suppliers with whom we can work out the practical issues"). Why hasn't it already been done? How much longer will it take?

Some lessons from recent history
IDAP requires us all to have an electronic ID which will allow us to identify ourselves on-line so that we can transact with the authorities.

The Home Office – or more specifically the Identity & Passport Service (IPS) – had eight years from 2002 to 2010 of unlimited budgets and unstinting political support to issue us all with ID cards, they had the whole of Whitehall behind them, every management consultant money can buy and most of the media, and yet they failed.

IPS couldn't settle on the objectives of the ID cards scheme, they couldn't make their case, they couldn't say what the point was, they didn't have enough registration centres, the chosen biometrics technology doesn't work, CESG refused to sanction DWP's database as the foundation for the National Identity Register, the public had concerns about data-sharing and the loss of personal privacy, and there were unanswered questions about the security of the system.

By paying airport workers to register and by leaning on Home Office staff to register, IPS finally managed to enrol about 30,000 (?) people on the National Identity Register, 0.07% (?) of the target population of 45 million, before giving up, kissing goodbye to at least £292 million of public funds – your money and mine – and having an institutional nervous breakdown from which they still haven't recovered.

Identity assurance requires trust on all sides and IPS destroyed it wholesale.

GDS haven't even started their eight-year march yet.

Two years ago, IDAP was nowhere. It still is.

No progress has been made.

Why did GDS make their promise to have IDAP operational by the Spring of 2013? Why haven't they announced yet that deployment will have to be delayed? Why are DWP still committed to testing UC from March 2013 and having it fully operational by October 2013?

What have GDS been doing all this time?

Three boondoggles and a talking shop
10 February 2012, ex-Guardian man Mike Bracken, Thoughts on my recent trip to the West Coast with Francis Maude, Minister for the Cabinet Office: "Andrew Nash, Google’s Director of Identity, ran us through the current issues facing identity.He explained how Google aim to grow and be part of an ecosystem of identify providers, and encouraged the UK Government to play its part in a federated system. The UK ID Assurance team and Google agreed to work more closely to define our strategy – so look out for future announcements. Andrew also took the opportunity to walk the Minister through the Identity ecosystem".

It's not known what Francis Maude made of his walk through the identity ecosystem. One way and another, though, Google were excluded from the list of official IDPs.

4 May 2012, ex-Guardian man Mike Bracken, Estonia’s technology economy and online service provision- back to the future?: "We came to see how a small country of 1.3 million has developed a culture and system of Governance and public service provision using the Internet and transparency as core principles ... Whilst we met dozens of people at breakneck speed, many of whom we hope to see in the UK soon, over the next week I will be explaining the wider points we have uncovered which reflect directly on our challenge to make public services in the UK digital by default, and how the Estonian experience links to our core principles".

Despite their links to the UK's core principles, there is no known Estonian among our IDPs.

29 May 2012, and GDS reported their trip to the White House, Steve Wreyford, Identity Assurance goes to Washington. Connected with which, 14 June 2012, Steve Wreyford, Cabinet Office joins the Open Identity Exchange – the OIX is a talking shop.

And that seems to be about it IDAPwise for GDS. A trip to California. A trip to Estonia. A trip to Washington. And signing up to a talking shop.

What else have GDS been up to?

Playing with computers
Using a team of up to 140, GDS have produced a new website, https://www.gov.uk (GOV.UK). That involved re-writing two existing websites, Directgov and Business Link. They are now in the process of re-writing most of the central government departmental websites and incorporating them into GOV.UK.

Why? It's a huge job and what's the point? Why go to the trouble?

Whatever the answers to those questions, GOV.UK is undeniably something GDS have done.

Unlike providing an identity assurance service.

Producing websites is obviously what GDS are at home with, it's what they enjoy and what they apply themselves to, it's what floats their boat:


Why re-write all these websites? GDS say that it's all something to do with improving the user experience of government websites. But what's a "user experience"? GDS offer no definition. In the end, arguably, GDS decide for themselves, inscrutably, whether they have improved the user experience:

 Early days but there's no answer to this tweet yet:

And they say that it's all something to do with a new approach to government. Ex-Guardian man Mike Bracken: "GOV.UK is not Government on the Internet, but of the Internet".

To them, the web is so special that there is something religiose about their mission and when they wanted a blessing for their work on GOV.UK, did they turn to a satisfied user whose experience had been improved? No, they turned to Tim O'Reilly. How did he get past security? How did he even know where the GDS building is?

The Government Gateway – convenience and/or security
Do we need a way to communicate with the government on-line?

Yes, of course we do.

And what's more, we already have a way and we have had for 10 years and more – the UK Government Gateway. Why throw that away? Are we so rich? We can afford to re-write websites and throw away the expensive originals? We can afford to throw away the tried and tested Gateway?

But if GDS have decided to throw it away, how can it take two years not to specify and develop the Gateway's replacement?

The objection to the Gateway is that it's hard to use. Millions of us manage but, yes, it's not easy. GDS promise something easier to use, something more like Facebook. They haven't developed a replacement, or even specified it, but that's what they promise.

But suppose that's impossible? Suppose that if you want a secure system, it just has to be more difficult to use than Facebook? Suppose that if a system is as easy to use as Facebook, then it just can't be secure?

These questions are unanswered. On the one hand, there is no proof that secure systems have to be relatively hard to use. And on the other, GDS certainly haven't provided any proof that "convenient" systems can be adequately secure.

Universal Credit
Universal Credit is important. Many people in the UK – maybe millions – are caught in the poverty trap set by our poorly-designed welfare system. UC could spring the trap and release them. They're not guinea pigs, we're talking about the lives of human beings here. While GDS are talking about computers.

Iain Duncan Smith is Secretary of State at DWP. How did he allow an important political initiative to be turned into an experiment for digital-by-default? If people were computers, digital-by-default might work but we're not, are we. Judging from outside:
  • DWP's and GDS's deadlines cannot possibly be achieved – how can Francis Maude say that "soon Identity Assurance Services will be used to support the Department for Work and Pension’s Universal Credit scheme"?
  • Iain Duncan Smith and his officials have increased the likelihood of UC failing.
  • DWP made a terrible mistake when they ceded control to GDS ...
  • ... they must take back control over identity assurance for UC ...
  • ... otherwise there will be no escape from the poverty trap.
  • GDS are simply not up to the job of providing identity assurance services ...
  • ... it's not their bag, it's not what they're interested in ...
  • ... let them play to their strengths, developing websites, and let them get out of the way of progress on UC.
----------

Daily Telegraph, 17 September 2012, Cyber attacks threaten welfare reforms, ministers warn:
Universal Credit is due to replace scores of individual benefits from next year, simplifying claims and allowing claimants to keep more of their benefits when they take paid work. The regime will be internet-based, with ministers intending that most claimants apply and report a change in circumstances online.

Appearing before a Commons inquiry into the reform, Lord Freud, the welfare reform minister, was asked what was the biggest risk to the programme. “I’ll say what the challenges are, what we need to get right: to get the security system working properly,” he said.

Private security companies will be commissioned to develop a system of “identity assurance” to check that only real claimants can get benefits. “That’s one of the biggest challenges,” said Lord Freud.

Universal Credit – GDS's part in its downfall

The importance of IDAP
If public services are to become digital-by-default the Government Digital Service (GDS) need to deliver on identity assurance.

It's their responsibility:
  • Ex-Guardian man Mike Bracken, the Chief Executive of GDS, is also the senior responsible officer owner for Her Majesty's Government's Identity Assurance Programme (IDAP).
  • GDS acknowledge an IDAP project on their blog.
  • And they said on 1 March 2012 that they want to ensure that "... ultimately, HMG-wide Identity Assurance is supplied across central departments via a common procurement portal ... and governed by the Cabinet Office [i.e. by GDS]".
And without IDAP, they say, people who want to use public services will not be able to assert their identities on-line and there will be no digital-by-default:
  • Francis Maude, Cabinet Office Minister, talking about digital-by-default on 6 March 2012: "... for all this to work users of digital public services need to be able to assert their identities safely, securely and simply".
How's it going? What progress is there on IDAP?

The savings to be expected from digital-by-default – a clarification

You thought you knew what savings are?
You thought you knew the point of digital-by-default?

Francis Maude said in his Foreword to the Government Digital Strategy that: "By going digital by default, the government could save between £1.7 and £1.8 billion each year ...".

Then in yesterday's Autumn Statement ("AS2012") the Chancellor said: "The recently published Digital Efficiency Report sets out how departments could save approximately £1.2 billion over the remainder of the current spending review period by continuing to move their transactional services online and become ‘digital by default’ ...".

So which is it? 1.2, 1.7 or 1.8? And are we talking about annual figures or the cumulative total over a period of years?

Time for some clarification.

We have tackled this matter before in Cutting costs/making savings, and GDS's fantasy strategy, where we made it clear that the £1.7/1.8 billion of estimated savings ...
  • represent annual figures,
  • exclude the cost of introducing digitisation (which might amount to £several billion),
  • exclude additional savings which could be made (or not), and
  • will be largely retained by the government (£1.1/1.3 billiion) ...
  • ... so don't go running away with the notion that tax rates might be reduced.
So what's the £1.2 billion? Where did that figure come from?

That's the amount that could be saved by digitisation "during the current spending review period" ("SR2010"), i.e. the five years 2010-11 to 2015-16. That's what the Government Digital Service (GDS) tell us in the Digital Efficiency Report, (p.2). They then promptly confuse the matter again by telling us on p.4 that the £1.7/1.8 billion figures quoted include savings that have already been made by digitisation – it's not all new money.

At which point you may start to feel that you're never going to see any of these savings even if they do materialise. But that's not the half of it. Even more savings you never get the benefit of could be made if only "legislative blockers" were swept away (p.3), those pesky laws of the land/cultural barriers/myths that stand between us and the new world of frictionless data-sharing, please see Alan Travis – Whitehall, the Guardian newspaper and Lord Leveson.

Digitisation has been going on in Whitehall for decades. Despite which, public spending rose by 59% in real terms between 2000-01 (£443.7 billion) and 2009-10 (£705.6 billion). Saving the odd billion by introducing a bit more digitisation is neither here nor there and it certainly isn't worth losing the wisdom of the anti-data-sharing laws which we currently have on the statute book for our protection.

As things stand, with those fusty old laws still in place, GDS reckon that Whitehall can get rid of about 40,000 public servants once digital-by-default is up and running (p.19). That's based on the example of the Driving Standards Agency (p.14) who have gone from 400 staff booking driving tests in 2003 to just 75 in 2012. And on the example of HMRC (p.15) who have got rid of 2,700 staff over the past five years as so many of us have taken to submitting our VAT returns et al on-line.

Has this mass redundancy programme been cleared with the unions?

And while we're waiting for an answer to that, how long do GDS intend to take over this digital-by-default project? The magic figure they're looking at is 82%.

That's the percentage of transactions with the state undertaken by people and companies digitally. And they reckon it could take 11 years or so to get there, long enough for several changes of permanent secretary, Cabinet Office Minister and government.

And if GDS have burned their way through billions by then and there are still no savings trickling down to the public, what then?

And if all our data gets hacked in cyberspace, what then?

The Minister is accountable to parliament. Not the officials. Not GDS.
