Siemens CEO Manages Emails and Meetings with 'OK'
Siemens CEO Roland Busch requires keeping the inbox under 100 emails and quickly handling daily communications with minimalist replies like 'OK' or 'No'.
Busch stated that having more than 100 emails in the inbox can cause managers to lose judgment on priorities; his approach is to respond immediately and minimize wording, and the team has adapted to this communication rule.
For matters requiring longer explanations, he does not write long emails at the computer but uses voice input while walking in the office to reduce time spent on text organization and email exchanges.
Busch has also eliminated fixed one-on-one meetings with direct executives. He requires the management team to come directly to his office when actual decision-making, support, or escalation is needed, with frequency ranging from multiple times a week to once a month.
This arrangement shifts management time from routine synchronization to on-demand processing: matters that do not require discussion are closed with very short emails, while complex issues are communicated via voice or face-to-face; this method relies on executives being able to identify when to report.
In market mechanisms, minimalist communication does not directly reduce R&D, manufacturing, or sales costs, but can compress management coordination costs in large organizations: information senders need to complete judgment and refinement first, while managers focus on exceptions and resource allocation. Beneficiaries are teams with clear decision-making authority, low-level dependency, and high autonomy; those under pressure are employees who require continuous guidance, repeated cross-department coordination, or are used to confirming consensus in meetings.

Roland Busch has served as Siemens CEO since 2021, previously holding positions as CTO, COO, and in digital industry management. Siemens spans industrial automation, digital industries, smart infrastructure, transportation, and medical technology ecosystems, with organizational complexity making executive schedules and internal communication scarce resources. His arrangement of 'write less, respond quickly, meet on demand' is not merely a personal efficiency preference but shifts the responsibility of information filtering from the CEO's inbox to the direct team.
In terms of capital and resource pathways, fixed weekly or one-on-one meetings can occupy the synchronous time of top executives and multiple senior managers, yet may not correspond to immediate decision-making. Busch chooses to handle low-risk matters with short replies, use voice for matters needing further explanation, and open his office for high-complexity issues, essentially prioritizing organizational bandwidth for high-value decisions like orders, R&D, customer interactions, investments, and risk escalations. The cost is that implicit information and weak signals are more likely to be delayed in exposure due to the absence of fixed communication windows.
Similar practices can be contrasted with Nvidia CEO Jensen Huang's management style of not having fixed one-on-one meetings and emphasizing broad information sharing; it also contrasts with Amazon's six-page memo system, which compresses impromptu expressions in meetings through longer written arguments. The commonality among the three is an attempt to reduce ineffective meetings, with the difference being that Busch uses short texts to increase processing speed, while Amazon uses long texts to enhance decision quality, depending on whether the matter requires auditable, cross-department consensus or complex technical justification.
Essentially, this represents a shift in pricing power: managers transfer the allocation of attention, a scarce resource, from fixed processes to the real-time issue presenters. The mechanism is that when the number of meetings and emails is low, the organization focuses on etiquette and synchronization; as information volume increases, fixed communication can crowd out critical decision bandwidth. By using clear response thresholds, short replies, and on-demand escalations, teams are forced to complete information compression and decision preparation first; however, if authority boundaries are unclear, minimalist communication can shift coordination costs to subordinates and amplify misunderstanding risks.
