THE SHORT ANSWER

McKinsey’s ICE work became controversial after ProPublica and the New York Times reported on internal documents describing hiring, detention and cost recommendations. McKinsey disputed the characterisation and denied recommending lower food or healthcare quality. Proposed changes, implemented changes and reported savings must be distinguished. The practical lesson is to make welfare standards and public duties binding constraints on an efficiency project.

A hiring proposal for an immigration agency

February the thirteenth, 2017. Three weeks into a new presidency. In Washington, a team from McKinsey and Company puts a slide in front of America's immigration agency. Its title: "Initiatives to improve ICE Hiring and address the Executive Order." The order called for ten thousand new immigration officers. McKinsey's idea was called "super one-stop hiring." Recruiting, screening and hiring, squeezed into a single day, in a rented gymnasium.

The goal: cut the time to hire by thirty to fifty percent. It was the start of a contract that would follow the firm for years.

The client

The client was U.S. Immigration and Customs Enforcement. ICE. Its deportation arm, Enforcement and Removal Operations, arrests, detains and removes people without permission to stay. Congress pays its bills. And its biggest bill is beds. In 2017, ICE's detention budget was nearly three billion dollars. According to ICE's own budget, one adult bed cost about one hundred and thirty-four dollars a day.

On an average day in 2018, ICE held more than forty-two thousand people. Much of that detention was run by private prison companies and county jails, paid under contract. One McKinsey slide put it plainly: "ICE is a significant and growing share of industry revenue."

How McKinsey got in

McKinsey did not arrive with the new president. It was hired under the Obama administration, to help with an "organizational transformation" of the deportation division. Federal contract records show a first paid job in March 2016. Then, on December the twenty-seventh, 2016, a bigger one: integrated management consulting, worth about twenty-three million dollars. Less than a month later, the White House changed hands.

And in January 2017, new executive orders directed "all legally available resources" to detention at the border.

Faster

The consultants got to work on speed. ICE's acting director at the time was Thomas Homan, a career immigration officer. By the summer of 2017, ICE had begun adopting the hiring ideas. In the end, ICE hired only a fraction of the ten thousand officers. The money was never there. But speed was also about removals.

An October 2017 ICE contracting document listed the "quantifiable benefits" of the work. Among them: "increased total removals and reductions in time to remove a detainee." In ICE's 2018 fiscal year, it removed more than two hundred and fifty-six thousand people. Up thirteen percent on the year before.

The detention budget

Then the consultants turned to the biggest bill. According to ProPublica, McKinsey proposed cuts in spending on food for detainees, on medical care, on supervision, and on maintenance. On March the thirtieth, 2017, an ICE supervisor wrote that McKinsey was "looking for ways to cut or reduce standards because they are too costly." The email added: "without sacrificing quality, safety and mission."

The firm also suggested moving detainees to cheaper places, often rural county jails. In the words of one document: "fill low cost beds before expensive beds." McKinsey also studied costs at ICE's largest family detention centre, in Dilley, Texas. A former official described heated meetings. ICE staff asked whether saving money on food and medical care was worth the human cost.

Can they do that?

In May 2017, the contract needed an extension, worth two point two million dollars. The document that justified it had been drafted by McKinsey's own staff. An ICE official asked the contracting officer: "Can they do that?" The answer: it "obviously isn't ideal to have a contractor tell us what we want to ask them to do." But, "what other option is there?"

ICE extended the contract.

THE MECHANISM

Three questions behind every claimed saving

  1. 01What was proposed?

    Identify the recommendation, baseline and mandatory standards.

  2. 02What changed?

    Verify which recommendation the institution actually implemented.

  3. 03Who experienced it?

    Measure service quality and human consequences alongside spending.

Our analytical framework. A recommendation is not an implemented policy, and neither is proof of a measured outcome.

Follow the money

So who gained what? For McKinsey, federal records show about twenty-six million dollars across its ICE task orders. For ICE, the agency says renegotiated detention contracts saved sixteen million dollars, with no "degradation to service." According to a former official, the most troubling ideas, on food, medical care and maintenance, never made it into those contracts. Internal emails credit most of the savings to fewer guards.

Put the numbers side by side. Sixteen million saved, in a detention budget of about three billion. Roughly half of one percent. The reported fees cover broader work than the cited detention-contract savings. These figures cannot establish a like-for-like return on investment.

Exposure

In June 2018, the Trump administration was separating migrant children from their parents at the border. ICE was at the centre of the storm. That month, a New York Times story about McKinsey's troubles in South Africa mentioned, in passing, its work for ICE. Many inside the firm had not known. Employees and alumni objected. On July the ninth, the Times reported that McKinsey was ending the work.

Its new global managing partner, Kevin Sneader, wrote that the firm "will not, under any circumstances, engage in any work, anywhere in the world, that advances or assists policies that are at odds with our values." ICE said the contract was simply expiring, as planned. A week after Sneader's announcement, according to ProPublica, McKinsey signed a two-million-dollar contract to advise Customs and Border Protection on its strategy. One slide listed, under border security, a single word: "Wall."

The reckoning

In December 2019, ProPublica and the New York Times published the full story, built on about fifteen hundred pages of ICE documents won through a freedom of information lawsuit. McKinsey pushed back hard. It said the work was agreed under the Obama administration, and its scope never changed in any material way. It said it never recommended lowering the quality of food or health care, and that much of its work was about finding contractors who were overcharging ICE.

ProPublica stood by its reporting, and said McKinsey had not challenged the documents. ICE said the work brought "measurable improvements," and denied it could harm detainees or their rights. A congresswoman, Pramila Jayapal, wrote to McKinsey asking for every cost-saving recommendation it made. This article concerns the documented contract controversy and the responses to it; it does not assert a comprehensive account of all possible later proceedings.

THE SEQUENCE

A timeline of the case

  1. Transformation work

    Consulting work began under the Obama administration. [1]

  2. Hiring and detention work

    Internal documents described operational recommendations. [1]

  3. Relationship ends

    The firm and ICE gave different accounts of the end of the contract. [1]

  4. Documents reported

    ProPublica and the New York Times published their investigation. [1]

  5. Public response

    McKinsey disputed the characterisation; ProPublica defended its evidence. [2]

THE PRACTITIONER’S LENS · OUR ANALYSIS

Cost optimisation begins with the service obligation

An efficiency project needs a definition of what must remain true after costs fall. In a detention setting, the baseline includes legal duties, healthcare, food, safety and the welfare of people who cannot choose another provider. Those constraints are not secondary measures to be considered once the financial recommendation has been selected.

The consulting question is therefore broader than which bed, meal or service costs least. It asks which operating arrangement fulfils the institution’s obligations at a justified cost. A model that omits a mandatory standard has not found an efficient solution; it has changed the problem being solved.

This is an analytical principle, not a finding that every recommendation in the historical engagement breached a standard. The reporting, the firm’s denial and ICE’s response need to be considered together. The article preserves the distinction between the disputed characterisation of advice and evidence that a particular policy was adopted.

A recommendation is not an implementation record

Internal slides can show what a team explored or proposed. They do not necessarily show what the client accepted, how the idea was modified, whether it was implemented or what happened afterward. Those are separate stages in the decision chain. An investigative timeline should identify the evidence available for each one.

For a present-day programme, keep a decision register with the recommendation, the official who approved it, any conditions, the implementation owner and the observed result. If a proposal is rejected, record that too. Otherwise a later review may mistake a list of options for a record of policy.

StageRequired evidenceCommon reporting error
ProposalDated recommendation and assumptionsTreating an option as an instruction
ApprovalDecision, owner and conditionsAssuming the sponsor accepted every idea
ImplementationOperational records and change dateInferring action from a slide
OutcomeMeasured results and comparable baselineAttributing every later change to the project

This proposed framework is useful in any operating-review deck. It becomes particularly important where a decision affects people who have limited power to challenge its consequences.

The fee-versus-savings comparison needs aligned scope

The documentary places reported consulting fees beside reported detention-contract savings. That comparison raises a fair question about value for money, but it cannot by itself answer it. The fees cover a wider set of work than the specific savings measure. The periods, implementation costs and attribution may also differ.

A valid return-on-investment calculation would identify the work included, the period of realised benefit and the cost of implementing the change. It would exclude benefits that would have occurred anyway and explain uncertainty. It would also account for service outcomes that the financial measure does not capture.

The article therefore treats the figures as contextual measures with different scopes. It does not subtract one from the other and call the result the project’s net value. A business-case model should enforce those definitions before a waterfall chart is used to persuade a committee.

A cost baseline can be technically fragile

The GAO’s detention-cost review provides a separate government analysis of estimation issues. It examined how bed rates and population assumptions affected budget estimates. That review should not be presented as a verdict on every consulting recommendation, but it explains why baseline quality matters.

If the starting estimate is unreliable, a claimed saving may reflect a modelling correction rather than an operating improvement. If population assumptions change, lower total expenditure may occur without lower cost per person. Conversely, a higher service standard can increase a unit rate while improving the institution’s performance against its mandate.

For a useful exhibit, show volume, unit cost and service scope separately. State whether the figure is a budget request, an obligation, an invoice or an observed expense. The labels are not technical decoration. They tell the reader what inference the number can support.

An illustrative standards-constrained model

Imagine a fictional institution comparing two facilities. Facility A has a lower daily price but requires additional transport, provides less access to required services and has a different capacity profile. Facility B has a higher quoted rate but avoids some of those costs. Choosing between them requires a complete service and cost definition.

The model should include transport, staffing, healthcare access, capacity and every applicable standard. Some criteria may be pass-or-fail rather than tradable against price. The approving official should see which options meet the requirements before the team ranks their cost.

These facilities and assumptions are illustrative. They are not claims about a particular ICE site. The exercise demonstrates why a recommendation to use a lower-cost location is incomplete until service equivalence and the full operating cost are established. The Allstate claims case offers another example of why a favourable financial measure needs an independent service-quality test.

Scope needs review when the mission changes

The work began before the change in presidential administration. That history is relevant, but it does not settle the scope or risk of every subsequent activity. A continuing contract can encounter new priorities, new instructions and a different operational environment. The engagement review should examine those changes directly.

For consulting firms, an escalation process should let staff raise a concern about a changed assignment without having to prove misconduct. The approving authority should assess the actual work, the institution’s mandate and the firm’s own commitments. A broad statement of values becomes useful only when someone can use it to make a concrete decision.

For public buyers, contract modifications should have a documented rationale and independent approval. A supplier may contribute expertise to defining the next phase, but the institution must remain responsible for deciding what it needs and whether the procurement route is justified. The France case examines that ownership of public advice.

Present the contested account fairly

ProPublica defended its document-based reporting after McKinsey challenged it. The firm’s denial of recommending lower food or healthcare quality belongs close to the relevant allegation. ICE’s stated view of the work also belongs in the account. A reader should not have to reach the source list to discover that the characterisation is disputed.

At the same time, displaying a denial does not remove the need to examine the documents. The article can explain the contradiction and the evidence on each side without pretending to resolve every disagreement. It should also avoid unsupported universal statements about the absence of all lawsuits or later proceedings.

The final strategy recommendation for a comparable project should show the saving, its evidence, implementation status and the people affected. If the team cannot state who carries the consequences and how mandatory standards are protected, the work is not ready for approval.

TAKE IT INTO THE NEXT MEETING

Three practical lessons

01

Write the non-negotiable standards first

Define food, healthcare, safety and legal requirements before calculating savings. A constraint must have an accountable owner and a measurable test.

02

Control changes in mission

Reassess an engagement when policy, leadership or operational priorities change. The same contract label can cover materially different risks.

03

Separate proposals from results

Maintain a decision log showing recommendations, approvals, implementation and observed outcomes. Do not present an idea or a modelled saving as realised impact.

Questions about the case

What is disputed about McKinsey’s ICE work?

Document-based reporting described recommendations involving detention costs and operations. McKinsey challenged the characterisation and denied recommending lower quality food or healthcare. Both the documents and that response are part of the account.

Did every reported recommendation become policy?

No such conclusion follows from a proposal. The reporting itself distinguished ideas from implemented contract changes. Each claim about implementation or harm requires its own evidence.

Can consulting fees be directly compared with detention-contract savings?

Only with aligned scope, period and attribution. The reported fee figure covers broader consulting work, while the cited savings concern particular contracts. Their difference alone is not a valid return-on-investment calculation.
