When­ev­er I speak to CEOs, divi­sion­al direc­tors or manag­ing direc­tors in the prop­er­ty sector, one obser­va­tion stands out time and again: most lead­ers do not suffer from a lack of infor­ma­tion. Quite the oppo­site, in fact.

Never before have those in charge had access to as much data, analy­sis, dash­boards, market reports and cours­es of action as they do today. At the same time, deci­sion-making cycles are becom­ing short­er, uncer­tain­ty remains high and the number of rele­vant issues is constant­ly increas­ing. Strate­gic trans­for­ma­tions, regu­la­to­ry require­ments, digi­tal­i­sa­tion, HR issues, geopo­lit­i­cal devel­op­ments and new tech­nolo­gies all compete for atten­tion on a daily basis.

The chal­lenge, there­fore, often does not lie in obtain­ing infor­ma­tion. The real chal­lenge lies in deriv­ing the right deci­sion from a multi­tude of options. It is precise­ly at this point that many today speak of ‘deci­sion fatigue’. More precise­ly, one could also refer to deci­sion over­load or deci­sion pres­sure caused by an infor­ma­tion over­load.

This does not refer to being over­whelmed or a lack of resilience. Rather, the term describes a real­i­ty of modern lead­er­ship: those who make many impor­tant deci­sions every day must manage their atten­tion, time and judge­ment carefully.

When infor­ma­tion makes deci­sion-making more difficult

Recent surveys show that this trend is not mere­ly a subjec­tive feel­ing. In a study commis­sioned by Oracle, 85 per cent of respon­dents in Germany stat­ed that the grow­ing volume of data makes deci­sions more compli­cat­ed. 55 per cent report­ed facing a deci­sion-making dilem­ma more than once a day. 69 per cent1had already avoid­ed making a deci­sion because they felt over­whelmed by the volume of avail­able information.

This trend is partic­u­lar­ly rele­vant to the prop­er­ty sector. The 2025 Digi­tal­i­sa­tion Study2  by the German Prop­er­ty Feder­a­tion (ZIA) and EY-Parthenon shows that 79 per cent of the compa­nies surveyed cite a lack of human resources and 75 per cent cite insuf­fi­cient data qual­i­ty as key factors hold­ing back digi­tal trans­for­ma­tion. At the same time, 90 per cent of respon­dents regard arti­fi­cial intel­li­gence as a key tech­nol­o­gy for the next five years.

The chal­lenge, there­fore, does not lie in provid­ing as much data and as many tech­nolo­gies as possi­ble. Rather, the crucial factor is to devel­op reli­able bases for deci­sion-making from them – and to recog­nise when addi­tion­al infor­ma­tion no longer yields any signif­i­cant new insights.

Thomas Dries, member of our active advi­so­ry board, recent­ly summed this up aptly in a conversation:

“At some point, a manag­er has to make a deci­sion. Wait­ing for that last five per cent of addi­tion­al infor­ma­tion certain­ly does not improve the qual­i­ty of the deci­sion any further.”

This is a notion that is more rele­vant than ever in many compa­nies. Para­dox­i­cal­ly, the desire for absolute certain­ty can lead to deci­sions being delayed, whilst oppor­tu­ni­ties slip away.

The over­all econom­ic situ­a­tion also increas­es the pres­sure to make deci­sions. In PwC’s 28th Glob­al CEO Survey, 56 per cent of German CEOs expect­ed a decline in domes­tic growth. Macro­eco­nom­ic volatil­i­ty, geopo­lit­i­cal devel­op­ments, cyber risks and the short­age of skilled work­ers were cited, amongst other things, as key risk factors.

In such an envi­ron­ment, the chal­lenge for lead­ers is not to elim­i­nate uncer­tain­ty entire­ly. It is about deal­ing with uncer­tain­ty in a struc­tured way, making assump­tions trans­par­ent and remain­ing capa­ble of taking action despite incom­plete information.

Beter struc­tures rather than more control

At the same time, we observe that many success­ful lead­ers very delib­er­ate­ly create struc­tures to ensure the qual­i­ty of their deci­sions. This includes the consis­tent dele­ga­tion of oper­a­tional matters as well as dialogue with trust­ed spar­ring partners.

In my recent arti­cle on ‘Invis­i­ble Lead­er­ship’, I explored the ques­tion of why effec­tive lead­er­ship often emerges in situ­a­tions where lead­ers do not have to make every deci­sion them­selves or be constant­ly visible.

Good lead­er­ship does not mean control­ling every process. Good lead­er­ship means provid­ing guid­ance, assign­ing respon­si­bil­i­ties and empow­er­ing people to act independently.

The Feder­al Insti­tute for Occu­pa­tion­al Safe­ty and Health (BAuA) also points out in a rele­vant publi­ca­tion that managers are partic­u­lar­ly frequent­ly confront­ed with high work demands. These include inter­rup­tions, intense pres­sure to meet dead­lines and perform, and having to juggle vari­ous tasks simul­ta­ne­ous­ly. Among managers with more than ten staff, for exam­ple, 64 per cent report­ed being frequent­ly disturbed and inter­rupt­ed at work.

These figures make it clear that the qual­i­ty of deci­sion-making does not depend sole­ly on indi­vid­ual expe­ri­ence or resilience. It also depends on whether an organ­i­sa­tion facil­i­tates focused work, clear lines of respon­si­bil­i­ty and suffi­cient time for reflection.

Nils Hüben­er, also an active member of our advi­so­ry board, put it this way:

“An impor­tant real­i­sa­tion from my profes­sion­al career was that not every impor­tant deci­sion has to be made on my desk.”

This state­ment may sound self-evident at first. In prac­tice, howev­er, it is anything but triv­ial. Those in posi­tions of respon­si­bil­i­ty often tend to want to manage as many issues as possi­ble them­selves. In the long term, howev­er, this creates a bottle­neck that not only limits one’s own effec­tive­ness but can also hinder the devel­op­ment of teams and organisations.

Dele­ga­tion does not mean hand­ing over all respon­si­bil­i­ty. It means distrib­ut­ing respon­si­bil­i­ty sensi­bly. The manag­er remains respon­si­ble for the direc­tion, the frame­work and the outcome – but they do not have to make every oper­a­tional deci­sion themselves.

Dissent as a mark of quality

Yet even the best struc­tures cannot replace the value of differ­ing perspec­tives. Partic­u­lar­ly at C‑level, the qual­i­ty of deci­sions is signif­i­cant­ly influ­enced by whether differ­ing opin­ions are permit­ted. Lead­er­ship does not mean always know­ing the right answer. Lead­er­ship often means asking the right ques­tions and surround­ing oneself with people who are prepared to contribute differ­ent perspec­tives and take on responsibility

This idea brings to mind a key aspect of my contri­bu­tion to the Pirate Lead­er­ship method­ol­o­gy. Progress often aris­es not from confor­mi­ty, but from people who chal­lenge exist­ing ways of think­ing, point out new paths and have the courage to swim against the tide.

For lead­ers, this means under­stand­ing construc­tive dissent not as a disrup­tion, but as an inte­gral part of good deci­sion-making processes.

The qual­i­ty of a deci­sion often depends on whether there are people in the room who are prepared to disagree. 

Psycho­log­i­cal safe­ty is a key prereq­ui­site here. Employ­ees must feel confi­dent that differ­ing views will not auto­mat­i­cal­ly be inter­pret­ed as disloy­al­ty or a lack of support. Only then will risks become appar­ent at an early stage, assump­tions be chal­lenged and alter­na­tives be seri­ous­ly considered.

A profes­sion­al spar­ring part­ner there­fore fulfils more than just an advi­so­ry role. They help to clar­i­fy prior­i­ties, expose assump­tions and exam­ine deci­sion options from differ­ent perspectives.

What char­ac­teris­es modern leadership

At a time when complex­i­ty is increas­ing rather than decreas­ing, this is precise­ly what becomes a deci­sive compet­i­tive advan­tage. After all, the best deci­sions are rarely made in isola­tion. They arise where expe­ri­ence meets differ­ent perspec­tives and discus­sion is encouraged.

For us at Valdivia, it is there­fore clear: modern lead­er­ship is not measured by how many deci­sions a leader makes. What matters far more is the abil­i­ty to set prior­i­ties, provide direc­tion and remain capa­ble of taking action even in the face of uncertainty.

Or to put it anoth­er way:

The best lead­ers do not make more deci­sions than others. They know which deci­sions truly deserve their attention.

The abil­i­ty to share respon­si­bil­i­ty, to allow for differ­ent perspec­tives and to main­tain clar­i­ty in complex situ­a­tions ulti­mate­ly links many of the lead­er­ship topics we regu­lar­ly explore at Valdivia.

Whether in the context of *Invis­i­ble Lead­er­ship*, *Pirate Lead­er­ship* or the ques­tion of how lead­ers cope with an ever-increas­ing flood of infor­ma­tion: the focus is always on the same chal­lenge – success­ful­ly guid­ing people and organ­i­sa­tions through change.

Voic­es from the Valdivia Advi­so­ry Board

What helps you person­al­ly to make good deci­sions, even when things are high­ly complex? “I try to distin­guish between urgent and truly impor­tant deci­sions. Not every­thing that makes a lot of noise is strate­gi­cal­ly relevant.”

What piece of advice would you give to young lead­ers? “Perfect infor­ma­tion is rare. Those who constant­ly wait for absolute certain­ty often miss the right moment to act.”

What role do spar­ring part­ners play in help­ing to make good deci­sions? “A leader isn’t judged by how often they’re right. What matters is whether they have people around them who feel free to open­ly chal­lenge them.”

Conclu­sion

Lead­er­ship does not mean making every deci­sion your­self. Lead­er­ship means enabling the right deci­sions to be made.
