Intel·ligència artificial Big Four Consultoria Auditoria Empreses

Les Big Four estan en crisi? IA, auditories deficients i conflictes d’interès

Deloitte, PwC, EY i KPMG afronten pressió per errors, conflictes i automatització. Però la seva concentració i responsabilitat regulada fan que parlar de col·lapse sigui prematur.

El vídeo de The Invisible Game anuncia el «col·lapse» d’unes empreses corporatives inflades i situa les Big Four —Deloitte, PwC, EY i KPMG— al centre del problema. Hi ha motius reals per parlar de pressió: auditories amb deficiències, conflictes entre assessorament i independència, escàndols públics i una IA que abarateix part del treball. Però no hi ha proves que el model estigui a punt de desaparèixer; aquestes xarxes continuen dominant l’auditoria de grans empreses.

El cas Deloitte: la IA no substitueix la revisió

El vídeo comença amb un encàrrec del Departament d’Ocupació i Relacions Laborals d’Austràlia. Deloitte havia de revisar un sistema que automatitzava sancions de benestar social. El contracte era de 440.000 dòlars australians, uns 290.000 dòlars nord-americans, i el primer informe contenia referències inexistents i una citació judicial fabricada.

La versió corregida va revelar l’ús d’Azure OpenAI i Deloitte va acceptar retornar l’últim pagament. El departament va afirmar que les recomanacions de fons no havien canviat, un matís que el vídeo omet quan presenta tot el treball com si l’hagués fet una màquina.

El problema no és simplement utilitzar IA. És lliurar un document que es presenta com a expert sense verificar-ne fonts, jurisprudència i atribucions. Una consultora pot automatitzar cerca, classificació i primeres redaccions, però la responsabilitat professional continua sent humana. Com més convincent és el text generat, més important és comprovar cada afirmació.

Com quatre xarxes van concentrar l’auditoria

Al minut 2:30, el vídeo retrocedeix als anys setanta. L’expansió de les multinacionals va crear demanda d’auditors capaços d’aplicar procediments coherents en molts països. Les Big Eight van anar fusionant-se fins a quedar cinc grans xarxes, i la caiguda d’Arthur Andersen després d’Enron en va deixar quatre.

Entrar en aquest mercat és difícil per raons que van més enllà de la marca:

  • cal personal i cobertura legal en moltes jurisdiccions;
  • les empreses cotitzades necessiten equips capaços de revisar operacions enormes;
  • hi ha requisits regulatoris, independència i assegurança professional;
  • un comitè d’auditoria prefereix una firma coneguda perquè el risc reputacional d’escollir-ne una de petita és alt;
  • el canvi d’auditor té costos de transició i aprenentatge.

Aquest cercle reforça la concentració: els grans clients exigeixen escala, i treballar amb grans clients és precisament el que dona experiència i reputació. No és un monopoli formal, però la possibilitat real d’elecció és limitada en la part més alta del mercat.

Enron va demostrar el risc sistèmic

Arthur Andersen cobrava a Enron per auditar els comptes i també per serveis de consultoria. Quan es va descobrir la manipulació comptable i la firma va perdre credibilitat, la xarxa es va desfer amb una velocitat extraordinària. El cas va impulsar la llei Sarbanes-Oxley i una supervisió més estricta als Estats Units.

La conseqüència paradoxal va ser més concentració. L’eliminació d’un gran competidor no va crear espai immediat per a desenes de substituts; va repartir els clients entre quatre xarxes. Això fa que una nova fallida sigui una amenaça per al funcionament del mercat, perquè moltes empreses tindrien encara menys auditors elegibles.

Per això «deixar caure» una Big Four no és tan simple com permetre que una empresa ineficient desaparegui. Els reguladors han d’elevar la qualitat sense desencadenar una crisi de capacitat.

Què significa una auditoria «deficient»

El vídeo cita un augment de deficiències en les inspeccions nord-americanes. Les dades de la Public Company Accounting Oversight Board mostren que, entre les sis grans firmes inspeccionades anualment, la taxa agregada de deficiències de la categoria més greu va passar del 12% el 2020 al 26% el 2022.

És un senyal preocupant, però no significa que el 26% de tots els comptes auditats fossin falsos. La PCAOB selecciona encàrrecs amb risc elevat i una deficiència indica que l’auditor no va obtenir prou evidència per sustentar la seva opinió o no va complir un requisit essencial. Pot existir sense que els estats financers continguin una incorrecció material.

Aquest matís no redueix el problema. L’auditoria es ven com a confiança: si el regulador no pot reconstruir com s’ha arribat a una conclusió, l’inversor no té la garantia per la qual paga. Les inspeccions també expliquen per què algunes firmes han reduït clients i invertit en control de qualitat.

Auditor i consultor: un conflicte incorporat

A partir del minut 10:23, el vídeo assenyala que l’assessorament genera una part enorme dels ingressos. El mateix nom comercial pot ajudar una empresa a implantar processos, tecnologia o estratègia mentre una altra part de la xarxa n’audita els resultats.

Les normes d’independència ja prohibeixen molts serveis a clients d’auditoria i obliguen a separar equips. Tot i així, els incentius i la informació confidencial continuen generant riscos. El cas més clar és PwC Austràlia: un soci que assessorava el Tresor sobre normes contra l’elusió fiscal va compartir informació reservada amb col·legues que ajudaven multinacionals a preparar-se davant aquelles mateixes normes.

Una investigació parlamentària va descriure els fets com una violació calculada de la confiança. PwC va acabar venent per un dòlar australià el negoci d’assessorament al sector públic, que es va convertir en Scyne Advisory. No és només un error de qualitat; és un exemple de com una xarxa pot monetitzar posicions incompatibles.

La IA erosiona l’avantatge d’escala, però no l’elimina

Les grans consultores han construït piràmides amb molts analistes joves que extreuen dades, revisen documents i preparen presentacions per a un nombre menor de socis. Els models generatius, la cerca semàntica i l’automatització poden reduir moltes hores d’aquest treball.

Això obre una oportunitat per a firmes especialitzades i professionals independents: un equip petit amb experiència sectorial pot produir una anàlisi competitiva sense milers d’empleats. Les mateixes eines també permeten que un client faci internament tasques que abans externalitzava.

Però el vídeo salta massa ràpid d’aquesta productivitat al «col·lapse». Les Big Four també compren tecnologia, tenen dades, relacions, responsabilitat contractual i capacitat per desplegar equips globals. En auditoria, a més, una IA no pot signar una opinió, assumir responsabilitat legal ni substituir l’escepticisme professional.

El cas Deloitte mostra els dos costats: la IA redueix el cost de produir un informe, però pot destruir valor si no hi ha traçabilitat i revisió. L’avantatge futur no serà només tenir l’eina, sinó demostrar controls que impedeixin que una al·lucinació arribi al client.

El relat de les «empreses inútils» és massa ampli

Un gràfic genèric o una recomanació buida és fàcil de ridiculitzar. Però una consultoria també pot aportar coneixement comparatiu, capacitat temporal, gestió d’una transformació o una veu externa quan l’organització està bloquejada. El valor depèn de l’encàrrec, l’equip, els incentius i la implementació.

La satisfacció baixa o els acomiadaments tampoc demostren per si sols que desaparegui la demanda. La consultoria és cíclica: quan les empreses retallen inversions i fusions, sobren equips; quan apareix una regulació o tecnologia nova, tornen a comprar ajuda.

La crítica més sòlida no és que tot l’assessorament sigui fum, sinó que la marca pot protegir treball mediocre i dificultar que el comprador valori el resultat. Els contractes haurien de definir evidències, responsables, conflictes, fonts, mètriques d’èxit i drets d’auditoria sobre eines d’IA.

Què pot canviar realment

És plausible que convisquin tres moviments:

  1. Les grans empreses internalitzaran anàlisi repetitiva i revisió documental.
  2. Firmes boutique competiran en problemes concrets on l’experiència pesa més que la plantilla.
  3. Les xarxes grans conservaran encàrrecs globals i regulats, però amb equips més petits i més tecnologia.

En auditoria, la concentració pot continuar perquè l’accés està limitat per responsabilitat i escala. En consultoria, la barrera és menor i la competència d’equips petits pot créixer més ràpid. Separar tots dos mercats evita assumir que una sola dinàmica els transformarà igual.

En resum

Les Big Four no estan col·lapsant, però el contracte implícit que justificava els seus honoraris s’ha afeblit. Les inspeccions han revelat problemes de qualitat, els conflictes han causat escàndols greus i la IA permet a clients i competidors fer part de la feina amb menys persones.

La resposta no és confiar cegament en la tecnologia ni en una marca. És exigir responsabilitat, fonts verificables, independència i un resultat mesurable. Si les grans firmes no ho ofereixen, la IA pot accelerar la pèrdua de confiança; si ho fan, la mateixa tecnologia pot reforçar-les en lloc de substituir-les.

    In December 2024, [music] the Australian government hired the world's largest corporate firm to give them advice on how to fix one of the country's most [music] pressing issues, an automated welfare system which penalized the nation's most [music] vulnerable. And after a rigorous 7-month brainstorm and $290,000 in [music] fees, the results were back. However, there was just one issue. All the hard work that Deloitte had been doing had been done by AI. The report included fake references, fake quotes from a fake court hearing, and even a citation to trusted academic work, all of which didn't exist. While this might seem like a somewhat extreme example, these firms have been getting away with dressing up obvious advice and solutions behind extreme [music] price tags for decades. That is, until the last couple of years. >> The accounting giant PwC is facing an existential crisis. Revelations that its senior partners misused confidential government information to help multinational tech companies avoid tax has rocked the firm to its foundations. >> Round after round of layoffs are starting [music] to puncture these big companies. But while the problem is most acute with the Big Four, [music] the same problems are showing up across pretty much the entire corporate world. Bloated firms that have gotten away with overcharging for decades are seeing their [music] business model begin to fall apart. And while you might think that the industry is just another [music] victim of the AI revolution, while in part that's true, there's actually a lot more going on here. Over the past few decades, [music] corporate America has hollowed out its competition. But doing that comes [music] with its own risks, and firms are only now just starting to pay the price. Okay, so pretty much anyone who's worked

    a corporate job knows that these companies can be a bit of a joke these days. In 2014, in what should have been a routine audit, PwC managed to overstate Tesco's projected quarterly profit by 250 million pounds, almost 30% higher than what they actually brought in. And events like these aren't a simple one-off. Time and time again, these companies have made massive mistakes on what should be fairly basic, if lengthy tasks. However, there was actually a time when these kind of American corporations [music] were the envy of the world for the high quality of work that they would do. >> [music] >> The 1970s saw the birth of the modern era of multinational corporations. After conquering America in the decades prior, [music] companies like IBM, Coca-Cola, and Ford began building operations that spread to every corner of the globe. But that presented a unique challenge. How do you keep track of money moving through [music] dozens of countries at once when every single one of those branches operates [music] under a completely different tax code and a different set of accounting rules? Ideally, you'd have one trusted, [music] independent outsider who could come in and check the books the same way everywhere, no matter which country you're operating in, which is what gave rise to these. Originally known as the Big Eight, they were firms which specialized in verifying companies' financial statements. They sat at the very heart of corporate America, helping run the biggest organizations in the Western world. By the late 1980s, the Big Eight together controlled about 98% of all public company audits. But gradually, as time went on, firms that couldn't keep pace with their bigger rivals got absorbed by them. So by the start of the 2000s, only five of the big original eight were left. Now, in theory, it's not anything unusual for

    the worst-performing firms [music] to go extinct. After all, that happens all the time to smaller corporations in history. But problems start to emerge when new firms aren't able to come into the [music] market at all. And in a sector like financial auditing, that's exceptionally difficult. Imagine you're running a multinational corporation [music] that sells cars across Europe, and it comes to that time of the year again, and you need to do an annual audit. You're presented with two options: a new startup audit firm that nobody has ever heard of, or one of the same multinational auditing firm who's been checking your books for decades and probably does the same for all your competitors and most of the governments of Europe. [music] On the balance of probability, you're probably going to go with the latter. After all, this isn't really the kind of thing that you want [music] to take a risk on. The point is, it's a world built on reputation and that's exceptionally difficult to build from scratch. So, over the last couple of decades, we've seen this same effect [music] of consolidation play out across all sorts of industries in corporate America. Three credit rating agencies, S&P, Moody's and Fitch, [music] collectively control about 96% of the global ratings market, a dominance they've held for over a century. And it's the same for strategy consulting. McKinsey, BCG and Bain dominate not because nobody else can do the analysis, but because we hired McKinsey is a much >> [music] >> easier sentence to say in a board meeting than we hired a firm that nobody has ever heard of. Law, finance, [music] asset management, private equity, all of these industries are increasingly dominated by a smaller and smaller number of firms. And in practice, that means these companies can get away with offering worse and worse services because they know that their buyers

    don't really have any sort of alternative. [music] Now, big corporations across all sorts of industries have been getting away with charging huge prices for sub-par services simply because they control enough of the market. And the same thing has been happening to your SIM card, especially when you go abroad, which is where the sponsor of today's video, Saylite, [music] comes in. Saylite is an eSIM app that works in over 200 destinations. It gives you instant mobile access the moment you land. No physical SIM card needed, no airport vendors and my personal favorite, no fumbling around with kiosks. [music] Pick your plan before you travel and the second you touch down, it activates and connects automatically. You get affordable data plans in multiple destinations without the expensive roaming fees carriers love to sting you with. Every plan you buy also earns you credit towards your next one.

As the quality of the services which a lot of the country relies on continues to decline, something is eventually going to go badly wrong. And in 2001, that's exactly what happened. By the late 1990s, Enron was one of the most admired companies in America, an energy trading giant worth tens of billions of dollars on paper, and its auditor was Arthur Andersen, one [music] of the Big Five. And the relationship between these two companies was extremely lucrative. In the year 2000 alone, >> [music] >> Andersen earned $25 million in audit fees and an additional $27 million in

  5. 6:34 , obre el vídeo en una pestanya nova

    consulting fees, both from Enron. However, behind the scenes, Enron was quietly hiding roughly $20 billion in debt off its balance sheet using a web of shell companies built specifically to make Enron look far more profitable than it really was. Of course, spotting that kind of manipulation was exactly what Arthur Andersen was getting paid for. They just completely failed. And when that came out, it cost the company so much that just 9 months down the line, they completely collapsed. [music] The trouble is, rather than learning the lesson from this that corporate America had become uncompetitive and needed to be broken up, the opposite ended up happening. Today, those four remaining audit companies audit every major organization in the Western world. Of the 500 biggest corporations in America, 498 are audited by these companies. [music] And when a firm picked which company they're going to go with, it takes them an average of 23 years to change once. This is BCE Inc., >> [music] >> Canada's largest telecommunications company, and it's been audited by Deloitte for 144 years. [music] Now, that might sound like a recipe for subpar service, and in many ways it is. But [music] as long as these firms could maintain the illusion of prestige, it just about works. The problem is, after decades of charging millions for orders that [music] aren't even accurate, people do eventually start to notice. In 2022, regulators found that 43% of EY's [music] orders had what they called a deficiency. Essentially meaning that the auditor didn't even gather enough evidence to actually support the opinion it was signing off on. The following year, they were forced to walk away from 84 audit clients, giving up $215 million in fees. And it's not just them, either. Regulators found that the average deficiency rate across all Big Four

  6. 8:15 , obre el vídeo en una pestanya nova

    firms more than doubled in just 2 years, from 12% in 2020 [music] to 26% by 2022. Given that, it's hardly surprising that firms are increasingly choosing to bring in what they call in-house, or moving these services out to smaller firms. And this isn't just an audit story. It's the same pattern playing out right across the corporate world. These giant firms spent decades building themselves [music] into effective monopolies on the back of the idea that what they did was so prestigious that nobody would ever seriously challenge them. However, the problem is, once they became safe, the quality began to quietly slip year after year, until eventually the firms that were supposed to be the kind of gold standard in the industry >> [music] >> are now the ones that are rubbish and don't even do the job they're paid for. Now, it's important to remember that a big part of why these firms were able to dominate for so long wasn't just their reputation, but the scale of cheap, high-quality labor that they could attract. [music] For decades, the best graduates from the best universities funneled straight into some version of accounting, law, or finance almost by default. At Harvard, roughly 57% of the class of 2022 went straight into finance, consulting, or technology. And that made it insanely hard for smaller firms to compete with them, as their name brands just didn't have the same CV attraction for fresh grads. But, ever since the introduction of AI, that advantage has been massively eroded. The very same tasks which gave these massive firms a competitive edge are exactly the kind of work that AI massively speeds up. [music] Data extraction, pattern matching, document review. The actual grunt work [music] that used to require armies of junior staff can now be done faster and cheaper by software supervised by a smaller and smaller

  7. 9:57 , obre el vídeo en una pestanya nova

    team. And perhaps most critically, none of this groundbreaking technology is exclusive to the old corporate [music] giants, which massively reduces the barrier to entry to compete in the market. Okay, so the sudden introduction of AI, along with the fact that the services the Big Four were providing just weren't that good, has meant that the companies have been bleeding clients for years now. But there's actually an even bigger threat to these companies which might bring them down even sooner. Government antitrust. Starting in the 1980s, what was then the Big Eight realized something very important. Given how good their reputations had become, they didn't just need to sell an actual service. [music] Instead, they could simply sell advice. That's what gave the rise to corporate management consultancies as we all know and love today. Deloitte Consulting, [music] PwC Strategy, EY Parthenon, and KPMG Advisory. They all almost exist as a branch of these original auditing firms. By 2023, the Big Four were pulling in 95 billion dollars from advisory services alone. More than the 66 billion that they made from audit and assurance combined. But it also presents a bit of a problem. Remember, the job of an auditing company is to independently verify that a company's financial statements are accurate. At the same time, the job of a consultancy is to try and improve how that same company runs. In effect, you've got the exact same company doing the [music] job and then evaluating how good a job it's done. It's like marking your own homework. This creates massive incentives for the auditing side of the business to sign off on the books a little too generously in order to make them seem like the consultant's advice is working better than actually is. And at the same time, the people doing the audits get access to a huge amount of confidential information, much of which would be

  8. 11:42 , obre el vídeo en una pestanya nova

    extremely profitable for consultants to quietly use to win new business or advise clients' competitors. Of course, doing so would be totally illegal. And in theories, these companies all have its strict internal Chinese walls to prevent this from happening. But as you might have expected, they aren't particularly effective. In 2013, the Australian Treasury hired a PwC partner named Peter Collins to help advise on new laws designed to stop multinational companies from dodging tax. He signed three separate confidentiality agreements, but he then shared that very same confidential government information with at least 53 PwC partners who used it to help clients, including Google, get ahead of a law PwC itself had helped designed. This kind of thing has been going on for decades across the Western world. And once a firm becomes successful enough to expand into several branches of the same industry, the temptation to use information it shouldn't really have to boost its position in both directions becomes almost impossible [music] to resist. But it does seem like governments might just be starting to notice. Following [music] the Australian PwC scandal, the company was forced to sell off its entire government consulting business for just $1. [music] And in the UK, from 2024, all four firms had to operationally separate [music] their UK audit practices from the rest of the business. Even the US, known for being the poster child of free market capitalism, has had Senate considering a breakup. For these businesses, getting split up this way would be totally detrimental for one key reason. Both sides of the business rely on each other. Consulting is clearly the main profitable arm, and in 2023, the Big Four alone generated $95 billion from advisory compared to $66 billion from audit. But it only exists in its current form because of the credibility and client access that auditing has

  9. 13:28 , obre el vídeo en una pestanya nova

    built up over a century. If you cut those things out from each other, chances are that both sides would end up doing a lot worse. And even if Western governments don't get involved, the quality of consulting services has dropped so much that it might not really matter. [music] Take a look at this slide from 2016. It's a key deliverable which McKinsey would have charged thousands of dollars for. And for the money, they get words like this: "Develop value-creating partnerships. Build a clear mission. Develop strategies to create a sustainable-related opportunities." These words are the output of millions of dollars, >> [music] >> and it's not like they actually mean anything. But with a fancy graph and a complimentary color tone, it seems like the advice must be valuable. Of course, you can only play that game for so long. By 2024, only 13% of businesses felt that consultants were actually doing more good than harm. Slowly but surely, firms and governments alike are beginning to cut contracts with these companies. And once the branch of the business that was propping up the entire operation starts shrinking, that puts the entire operation under massive pressure. Okay, so all of this raises an important question. What actually ends up filling the space they leave behind? The most obvious option is that large companies simply stop outsourcing this work altogether. If the main value the Big Four provided was cheap, high-quality labor to do data extraction and document review, and AI can now do most of that work internally. And then a company doesn't really need to pay millions of dollars to a consultancy just to get an outsider's opinion on something its own staff could generate in an afternoon. At the same time, it's also very possible that we see a wave of smaller boutique firms start to compete

  10. 15:03 , obre el vídeo en una pestanya nova

    seriously for the first time in decades. AI is quickly closing the gap in output quality between a firm with 300,000 employees and a firm with 30, meaning that the size of your head count stops being the advantage it used to be. And the third, perhaps most disruptive possibility, is that the work stops requiring a firm at all. Historically, one of the reasons you needed a firm, rather than a single expert, was that any serious piece of consulting [music] or audit work required more labor than one person could physically produce in a reasonable time frame, which is why these companies were built around armies of junior staff supporting [music] a smaller number of partners. If AI can now do the bulk of that supporting work, then a single experienced professional, someone who spent 15 years inside one of these firms and understands exactly what clients are paying for, could possibly deliver the same output on their own without needing hundreds of junior employees behind them. This would create an entirely new category of competitor [music] that doesn't really resemble a firm at all, made up of independent consultants who can undercut the Big Four dramatically on price simply because they don't have the overhead of a firm to support. Of course, none of these outcomes are mutually exclusive, [music] and it's entirely possible that all three end up happening at once, chipping away at the Big Four from different directions simultaneously. What does seem fairly clear, though, is that the model which dominated corporate America for the better part of a century is no longer guaranteed.
