Tod durch Meeting: Eine Leadership-Fabel zur Verbesserung Ihrer Besprechungskultur
by Patrick M. LencioniCasey McDaniel war noch nie in seinem Leben so nervös gewesen. In 10 Minuten sollte DAS Meeting beginnen, und Casey hatte allen Grund zur Annahme, dass sein Auftritt während der nächsten 2 Stunden über seine weitere Karriere, seine finanzielle Zukunft und das Schicksal seiner Firma entscheiden würde. "Wie konnte mein Leben nur so rasend schnell völlig aus den Fugen geraten?", fragte er sich. In seinem Bestseller bietet Patrick Lencioni ein Heilmittel für das wohl schmerzhafteste und dennoch unterschätzteste Problem im heutigen Geschäftsleben: schlechte Meetings. Und was er vorschlägt, ist simpel und revolutionär zugleich. Der Gedanke an Meetings verursacht bei den meisten Managern und Mitarbeitern Bauchschmerzen. Aber sie sind nun mal ein unverzichtbarer Bestandteil der Arbeit. Anhand einer Leadership-Fabel, der dazugehörigen Theorie und praktischen Tipps zeigt Lencioni, wie Meetings von einer anstrengenden und nervenaufreibenden Angelegenheit zu produktiven, fesselnden und energiergeladenen Ereignissen werden können. In der Fabel begegnen wir dem CEO Casey McDaniel, der die katastrophale Meetingkultur in seinem Unternehmen unbedingt verbessern muss, aber nicht weiß wie. Ihm hilft schließlich ein respektloser, junger Berater, Will Petersen, mit einigen unkonventionellen und radikalen Ideen zur Lösung des Problems (Meetings müssen dramatischer und konfliktgeladener sein, um nicht zu langweilen, und Meetings sollten kontextbezogene Strukturen aufweisen). Das Buch ist ein Blueprint für Führungskräfte, die endlich wissen wollen, wie sie ihre Meetings optimieren können, damit Zeit sparen und Frustration verhindern sowie eine Kultur voller Energie, Leidenschaft und Engagement schaffen können.
Napoleon Hill's Goldene Regeln: Zeitlose Weisheiten fur Ihren Erfolg
by Napoleon HillNapoleon Hill gilt als der Vater der persönlichen Erfolgsliteratur. Zum ersten Mal in Buchform findet sich hier eine Serie von Artikeln, die Hill zwischen 1919 und 1923 veröffentlicht hat. Napoleon Hill, der selbst in sehr ärmlichen Verhältnissen aufwuchs, beschäftigte sich zeitlebens leidenschaftlich mit dem Rezept für bzw. der Erreichung von persönlichem und finanziellem Erfolg. Dafür studierte und interviewte er im Auftrag des Stahl-Tycoons Andrew Carnegie über 500 der berühmtesten und reichsten Personen seiner Zeit, u. a. Henry Ford, Thomas Edison, Alexander Graham Bell und John D. Rockefeller. Basierend auf diesen Interviews entwickelte Hill seine Erfolgsphilosophie - eine Philosophie, die von ihrer Aktualität und Anwendbarkeit seitdem nichts eingebüßt hat. Sie fand Eingang in seine in diesem Buch veröffentlichten Artikel - kleine aber feine Goldstücke unschlagbarer Weisheit: inspirierend, motivierend und zeitlos. Die goldenen Regeln beschäftigen sich mit Themen wie: Suggestion, Selbstvertrauen und der Kraft des Geistes. Viele seiner Gedanken wurden in den folgenden Jahrzehnten immer wieder von späteren Autoren aufgegriffen und neu verpackt. Das Original ist und bleibt aber das Beste.

Courage: Mehr Mut im Management
by Stefan Tilk"Wir sind Weltmeister im Zögern und Zaudern." Passender als mit dieser Aussage von Jochen Kienbaum von Kienbaum Consulting kann die aktuelle Situation in Deutschland und das Verhalten seiner Manager nicht beschrieben werden. Die weltweite Finanzkrise, zahlreiche Unternehmensbankrotte, Banken vor dem Aus, Massenarbeitslosigkeit und Sozialsysteme gefährdet - es gibt genug Gründe, den Mut zu verlieren. Aber hilft uns das? Schluss mit Jammern und weichen Knien fordert Stefan Tilk. Gerade in den Unternehmen braucht es Manager, die sich trauen, Probleme anzupacken, die wissen, wie man das Ruder herumreißt und wieder auf Erfolgskurs kommt. Das einzig Richtige in Deutschland wäre, das wieder zu entdecken, was viele in den letzten Jahren mehr oder weniger verlernt haben: Mut im Management. Mut ist keine abstrakte Tugend, Mut ist eine konkrete Fähigkeit, die Managern täglich, und besonders auch in solchen Turnarounds, abverlangt wird. Stefan Tilk weiß, wovon er redet. Er hat schon mehrere Krisensituationen in Unternehmen erfolgreich gemeistert. In seinem Buch zeigt er, wie und womit Manager Turnarounds schaffen können. Betrachtet werden einerseits Manager, die in Augenblicken der Wahrheit aus Feigheit "gekniffen" haben und andererseits die wenigen Vorbilder, die Mut bewiesen und einen Wandel bewirken konnten.
Die tägliche Mutprobe: Rückgrat zeigen, Entscheidungen treffen und gemeinsam bestehen
by Christian ZipfelZipfels neues Buch ist wieder eine Business-Fabel: Der Erzähler muss erleben, wie das Unternehmen, in dem er arbeitet, in Schieflage gerät. Chefs werden am laufenden Band ausgetauscht, Strukturen verändert. Entscheidungen werden kaum kommuniziert, oder gar nicht erst getroffen - stattdessen brodelt die Gerüchteküche und Sorgen um die Zukunft machen sich breit. Stück für Stück entdeckt der Erzähler die Symptome und Ursachen mangelnder Courage im Unternehmen, und erkennt, wie diese im Zusammenhang mit der aktuellen Krise stehen. Neben mangelnder Kommunikation und dem Problem fehlender Entscheidungen durchlebt er frustrierende Feedbackgespräche, wird von seinem Vorgesetzten genötigt, kritische Berichte zu frisieren und muss mit ansehen, wie so genannte Führungskräfte in dieser brisanten Zeit versuchen, ihre Besitzstände zu sichern und nirgends negativ aufzufallen. Er beginnt, sich der allgemeinen Lähmung zu entziehen und wagt sich aus der schützenden Anonymität. Anfangs läuft es gut, bis er es eines Tages übertreibt ... In diesem Buch zeigt Christian Zipfel auf, warum couragiertes Handeln in Unternehmen verloren geht und wie es sich wieder beleben lässt - ohne die eigene Karriere zu riskieren und es erwartet Sie ein Wiedersehen mit Thomas, dem Helden aus "Jour fixe um 6"!
Die funf entscheidenden Fragen des Managements
by Peter F. DruckerDer clevere Begleiter für die Hemdtasche des Managers. Mit fünf einfachen und doch komplexen Fragen wird auf die essenziellen Bestandteile und Verbesserungsmöglichkeiten des Managements von Unternehmen aufmerksam gemacht.
Managerismus: Unternehmensführung in Not
by Manfred Hoefle Hoefle ManfredThe term "managerism" coined by the author describes the form commonly found today of how companies are led, how added value is used and how people and values are treated. Advised by external consultants and stimulated by financial analysts, many managers have adopted a certain distance to their employees, who are now generally known as "FTEs", "headcount", or "human capital". Only recently have we been experiencing a lack of solidarity among company sites or divisions, a decrease in social responsibility and a loss of values. This development first seen in Germany in the 1990ers first culminated in the Internet-hype at the turn of the millennium and again during the recent bank crisis; it recurs at ever diminishing intervals. Manfred Hoefle describes the phenomenon of managerism as a generic defect among the management of predominantly listed companies. Mainly it is a deformation of management, as observed and taught by Peter Drucker. Or to put in another way: It is Gresham's Law: Bad behavior expels good behavior, because it is supposedly more successful. The reasons for this are: - penetrating capital markets, - the drifting apart of nominal and real economics, - intensified competition, - the systemic results of large-scale organization, - the basic constitution of humans or "organization men", and - the effects of news- and story-triggered media, arrogant consultants and interventionist politicians. Particular facets of managerism are illustrated in the manner of warnings, such as mercenaries in management, and the role of the consultant as "shaping fashions", etc. The book names and describes the deformation in concrete terms, while at the same time showing ways to escape and help.

Supercapacitors
by Max Lu Francois Beguin Elzbieta FrackowiakSupercapacitors are a relatively new energy storage system that provides higher energy density than dielectric capacitors and higher power density than batteries. They are particularly suited to applications that require energy pulses during short periods of time, e.g., seconds or tens of seconds. They are recommended for automobiles, tramways, buses, cranes, fork-lifts, wind turbines, electricity load leveling in stationary and transportation systems, etc. Despite the technological maturity of supercapacitors, there is a lack of comprehensive literature on the topic. Many high performance materials have been developed and new scientific concepts have been introduced. Taking into account the commercial interest in these systems and the new scientific and technological developments now is the ideal time to publish this book, capturing all this new knowledge. The book starts by giving an introduction to the general principles of electrochemistry, the properties of electrochemical capacitors, and electrochemical characterization techniques. Electrical double layer capacitors and pseudocapacitors are then discussed, followed by the various electrolyte systems. Modelling, manufacture of industrial capacitors, constraints, testing, and reliability as well as applications are also covered. 'Supercapacitors - Materials, Systems, and Applications' is part of the series on Materials forSustainable Energy and Development edited by Prof. G.Q. Max Lu. The series covers advances in materials science and innovation for renewable energy, clean use of fossil energy, and greenhouse gas mitigation and associated environmental technologies.
