این کتاب درسی کلیدی، دانشجویان را با حوزه روانشناسی صنعتی و سازمانی آشنا می‌کند و توضیح می‌دهد که چگونه روانشناسان صنعتی-سازمانی، کار و فعالیت را بهبود می‌بخشند. این کتاب توضیح می‌دهد که چگونه روانشناسان صنعتی-سازمانی به سازمان‌ها کمک می‌کنند تا بهترین افراد را استخدام کنند، کار را ایمن‌تر و کم‌استرس‌تر کنند و از مدیران و رهبران حمایت می‌کنند تا در رهبری دیگران مؤثرتر باشند. همچنین توضیح می‌دهد که چگونه روانشناسان صنعتی-سازمانی با سازمان‌ها همکاری می‌کنند تا تنوع در نیروی کار را بپذیرند، محیط فیزیکی کار را به بهترین شکل برای کارکنان طراحی کنند و محصولات و خدمات خود را به مصرف‌کنندگان عرضه کنند.

ویژگی‌های کلیدی این نسخه عبارتند از:

پوشش هر دو حوزه موضوعی اساسی و سنتی صنعتی-سازمانی مانند تحلیل شغل، انتخاب کارکنان و انگیزه کاری، و همچنین حوزه‌های موضوعی که امروزه در محیط‌های کاری مهم هستند مانند استرس و رفاه، عوامل انسانی و آمادگی برای مشاغل آینده.

پوشش جدید یا گسترده‌تر تیم‌ها در سازمان‌ها، کار از راه دور/ترکیبی، ترک آرام و مسائل مربوط به تنوع، برابری و شمول،

یک فصل روش‌های ساده که بیشتر بر روش‌های خاص مورد استفاده روانشناسان صنعتی-سازمانی، مانند گروه‌های کانونی، نظرسنجی‌ها و نظرسنجی‌های گالوپ تمرکز دارد.

این کتاب که سرشار از ابزارهای آموزشی متنوع و مثال‌های دنیای واقعی است، برای دانشجویان کارشناسی در دوره‌های مقدماتی روانشناسی صنعتی-سازمانی یا روانشناسی رفتار کاری جالب خواهد بود.
