When DHL upgraded its AI-powered voicebot last year, the post and parcels team in Germany checked the transcripts of its interactions and noticed a problem. The bot often failed to recognise the word \u201cJa\u201d \u2014 German for Yes.<\/p>\n
Spotting and ironing out such a fundamental glitch \u201cwas a telling example of how important it is [with artificial intelligence] to take the time and do the analysis of what\u2019s working well and what\u2019s working less well,\u201d says Benjamin H\u00fcbner, who runs consumer customer services for the division.<\/p>\n
The voicebot is one result of efforts by DHL to apply AI to some of the trickiest problems facing the logistics industry and German business. Its progress shows how companies are embedding the technology deep inside their processes. <\/p>\n
Faced with an ageing workforce and a surge in ecommerce, the German business says AI will plug looming staff shortages rather than force lay-offs. But on the path to the future, the group, which owns Deutsche Post and recently announced cuts to its 187,000-strong German post and parcels division, has to navigate tight rules, mandatory consultations and the concerns of workers.<\/p>\n
Speaking in January 2024, DHL management board member Nikola Hagleitner contrasted the generally positive attitude of managers with the worries of front-line teams staffing call centres or delivering mail. The first group was \u201ctalking about gen AI and what gen AI can do, and how fantastic the world will be. But I have a big group of people who fear that their jobs are going to be lost\u201d.\u00a0<\/p>\n
Bernd Gemein, chief information officer for post and parcels, says the prospect of AI taking on more work is still \u201crather frightening for those who do repeat control, accounting or invoicing [jobs] or [handle repetitive] customer calls\u201d.\u00a0<\/p>\n

Angela Schoellig, a professor of robotics and AI, says that rather than worrying about job losses, workers now have a \u2018general perception that we may need [technology] to keep the health and the wealth of the country\u2019 \u00a9 Astrid Eckert\/Technical University of Munich<\/p>\n
But the fear is tempered by an awareness of how technology can address Germany\u2019s pressing demographic challenge. DHL has already pushed automation and AI through its warehouse and transport operations, where, among other things, it helps sequence orders, make the most of shipment space and predict volumes. Since 2020, employment in that division globally has risen by 17 per cent. According to Angela Schoellig, professor of robotics and AI at the Technical University of Munich, when she talks about automation she is no longer asked whether robots will take people\u2019s jobs. Instead, \u201cthere\u2019s a shift in the general perception [to the idea that] we may need these [innovations] to keep the health and the wealth of the country\u201d.\u00a0<\/p>\n
At DHL in Germany, one in three staff working in support operations will retire in the next five years, taking with them decades of institutional memory. \u201cEveryone in Germany understands that if you don\u2019t automate and use AI, you won\u2019t be able to deal with the shrinking workforce,\u201d says Gemein.<\/p>\n
For those carrying parcels and letters, the fear of a robot takeover is offset by an understanding that AI \u201ccan\u2019t walk through the suburbs and deliver parcels\u201d, Gemein says. Technology is helping here, too. In its search for workers, the group already employs a vast range of nationalities in the German delivery service, and handheld scanners used by staff already translate customers\u2019 messages about, say, where to leave parcels, into 20 languages.<\/p>\n
As staff leave, AI is helping plug holes in the company\u2019s knowledge base. Outgoing workers document procedures they follow and some attend an exit \u201cinterview\u201d with an AI tool trained on DHL\u2019s official manuals. \u201cThe AI asks \u2018have I understood the process?\u2019 and the person might say \u2018that\u2019s right, but there\u2019s this exception\u2019,\u201d explains Gemein. The tool updates itself with the additional knowledge which can then be used to train new recruits. AI is also making training materials more engaging, with staff encouraged to create short videos to explain new processes or services.<\/p>\n

DHL\u2019s group head of corporate development Yin Zou calls the group\u2019s closed hub Gaia a \u2018safe playground\u2019 where staff can experiment with AI \u00a9 DHL Group<\/p>\n
DHL\u2019s generative AI experiments are happening on a group-wide closed hub, called Gaia, set up four months after OpenAI released ChatGPT for public use in 2022. Group head of corporate development Yin Zou describes it as a \u201csafe playground\u201d. Rather than be wedded to one large language model (LLM), DHL encourages staff to test options and experiment with novel AI agents, such as an assistant to help master the complexities of cross-border customs coding.<\/p>\n
Still, it took six months to win approval for guidelines about the use of AI and Gaia from the German operation\u2019s works councils, elected by employees to represent their interests. One early concern was that colleagues might enter sensitive data into unfenced LLMs. But the speed AI is developing demands a new approach to such discussions, says Dirk Schneider, a 40-year veteran of DHL who now chairs the works council for DHL\u2019s German headquarters. \u201cIt\u2019s so much faster than the old IT tools\u201d, which used to change every six to 12 months, he says. Workers\u2019 representatives are now negotiating with managers for a deeper agreement on principles, to speed up adoption of tools and improve security.<\/p>\n
Regulation also places limits on how far DHL can go to develop some AI tools in Germany. A conversational customer service voicebot could infringe German postal law if it were to go off-message, so the current version is programmed to respond strictly within the rules and hand over to a human if it cannot provide an answer. Even this model already handles 1mn calls a month and can settle half of all queries without human intervention. As the bot\u2019s ability to \u201cunderstand\u201d inquiries improves, customers no longer have to repeat their delivery number several times. Following complaints about, say, broken delivery lockers, the latest version automatically sets up a technician\u2019s visit rather than simply logging the defect.<\/p>\n

One DHL customer service agent, who declined to be named, says the voice recognition software still struggles, \u201cespecially when it comes to [dealing with] dialects or very different speaking styles\u201d. But they agree it has reduced repetitive tasks. H\u00fcbner says most users \u201care thrilled by how easily it works\u201d, adding the bot frees employees up to \u201cuse their valuable human brain to solve the customer problem\u201d.<\/p>\n
In March, DHL announced plans to cut 8,000 jobs in its German post and parcel division this year, but the company says that was related to the challenging economic environment not directly to technology. <\/p>\n
Gemein says the group has not laid off any contact centre staff in Germany, but nor does it have to replace as many of those who leave voluntarily or hire temporary workers to cover pre-Christmas peaks. Human customer service agents are retraining in jobs such as \u201cconversation designers\u201d, working out which problems can safely be handed to the voicebot. Those who supervise call centre teams now act as \u201cquality assurers\u201d, making sure mistakes made by the AI are corrected, not amplified at scale.<\/p>\n
\u201cThere are questions [from staff] and a certain level of insecurity,\u201d says H\u00fcbner. \u201cBut that changes [when] people see the benefits of it in their day to day work.\u201d<\/p>\n
One way in which the German group has sought to improve acceptance from sceptical employees is by encouraging them to think of AI \u201cnot as a superintelligent master, but as an older colleague\u201d, Gemein says.\u00a0<\/p>\n
\u201cI think it\u2019s the future,\u201d adds Schneider. \u201cYou can\u2019t work without it. Whether you love it or hate it, you have to work with it. So make the best of it.\u201d <\/p>\n
