This cumulative dissertation covers the concepts of scenario-based strategic planning and strategic management in family firms over five articles. The first article gives an overview of the cumulative dissertation explaining the research gap, approach and contribution of the dissertation. The paper highlights the two research areas covered by the dissertation with two articles focusing on scenario-based strategic planning and two on strategic management in family firms. The second article is the first of two focusing on scenario-based strategic planning. It introduces and describes a set of six tools facilitating the implementation of scenario-based strategic planning in corporate practice. The third paper adapts these tools to the financial management and controlling context in private companies highlighting the tools’ flexibility in managing uncertain and volatile environments. The fourth article is the first of two focusing on strategic management in family firms. It analyzes organizational ambidexterity as a factor explaining family firm performance. The article shows that a high level of organizational ambidexterity in family firms leads to a higher family firm performance. The final paper concludes the dissertation examining the tendency of family firms to focus on capability exploration or resource exploitation over different generations managing the family firm.

Der Anteil der externen Nachfolge bei eigentümergeführten bzw. Familienunternehmen nimmt stetig zu. Eine Möglichkeit ist dabei ein Management-Buy-In, bei dem ein externer Manager die Position des Altinhabers übernimmt. In einer solchen Situation kann die Nachfolge in Form einer Relay Succession erfolgen, eine zeitlich gestaffelte Übergabe vom alten an den neuen Inhaber. In dieser Arbeit werden die Relay Succession, ihre Vor- und Nachteile, relevante Einflussfaktoren und Prozessempfehlungen in qualitativen Fallstudien untersucht.:Vorwort … II Inhaltsverzeichnis … III Abbildungsverzeichnis … VIII Tabellenverzeichnis … IX Abkürzungsverzeichnis … X 1 Einleitung … 1 2 Management-Buy-In bei eigentümergeführten Unternehmen … 6 2.1 Definition eigentümergeführter Unternehmen und Familienunternehmen in dieser Untersuchung … 7 2.2 Wirtschaftliche Bedeutung … 9 2.3 Bedeutung des Geschäftsführers und seiner Nachfolge … 13 2.4 Externe Nachfolge in eigentümergeführten Familienunternehmen … 16 3 Aktuelle Forschung … 27 3.1 Rahmengebende Forschungsfelder … 28 3.2 Zusammenfassende Beurteilung der theoretischen Grundlagen … 66 4 Untersuchungsmethode und empirische Betrachtung … 80 4.1 Qualitativer Fallstudienansatz … 80 4.2 Selektion und Akquirierung von Fallstudienkandidaten … 85 4.3 Interviewführung und fortlaufende Auswertung … 89 4.4 Datenanalyse und Hypothesengenerierung … 97 4.5 Sicherstellung der Reliabilität und Validität der Fallstudienuntersuchung … 102 5 Beschreibung und individuelle Beurteilung („within analysis“) der Fallstudien … 107 5.1 Fallstudie Fenster … 107 5.2 Fallstudie Karton … 114 5.3 Fallstudie Kunststoff … 121 5.4 Fallstudie Logistik … 131 5.5 Fallstudie Medizin … 140 5.6 Fallstudie Metall … 147 5.7 Fallstudie Möbel … 157 5.8 Fallstudie Netzwerk … 166 5.9 Fallstudie Präsentation … 174 5.10 Fallstudie Zahn … 181 6 Übergreifende Diskussion („cross-case analysis“) … 188 6.1 Ergebnisse … 189 7 Fazit … 241 7.1 Zusammenfassung … 241 7.2 Implikationen für die Praxis … 243 7.3 Einschränkungen und Grenzen … 247 7.4 Zukünftiger Forschungsbedarf … 249 A Appendix … A-I Literaturverzeichnis … A-XLIX

Purpose – The aim of this paper is to provide evidence on the extent and the consequences of the provision of non-audit services (NAS) by statutory auditors to German family firms. Design/methodology/approach – The study analyzes hand collected fee data of 368 listed and private family firms in Germany. It employs univariate tests, ordinary least squares and two-stage least squares regressions to investigate potential threats to perceived auditor independence and knowledge spillovers between jointly provided NAS and audit services. Findings – Incumbent auditors are shown to be a significant source of various types of NAS to family firms. There is weak evidence on threats to perceived auditor independence and support for reciprocal knowledge spillovers between the services. While listed and private family firms do not differ in regard to the proportion of NAS fees, comparative findings suggest that key threats and benefits of jointly provided services are more prevalent among private than among listed family firms. Research limitations/implications – The study suffers from limited data availability and is restricted to the initial year of mandatory audit fee disclosure of private firms in Germany. Particularities of family firms and the German setting, as well as differential results for listed and private family firms, suggest fruitful avenues for future research. Practical implications – The study addresses the current issues in audit regulation. Regulatory bodies should consider that key threats and benefits of auditor-provided NAS decrease with stronger exogenous restrictions. Attempts to restrict jointly provided services in the EU suggest family firms to reconsider their reliance on auditors as a trusted source of NAS. Originality/value – This study is the first to provide evidence on the extent and consequences of auditor-provided NAS in family firms based on fee disclosure. It is also among the few studies that investigate private firms in a code law country and complements prior evidence from Germany that is restricted to listed firms. More generally, it contributes to limited evidence at the intersection of audit and family business research.
