Companies that chase every possible opportunity never develop unique advantages or defensible moats.
And focus IS the best way to start a business. Find a niche. Then expand.
But focus is not the ultimate destination.
Integration is.
Let me explain...
On some level, all human value is "integrative."
We produce the most value when we integrate multiple spheres of competence.
Look at the design of this room (from a great hotel in London, the Haymarket).
To design a room like this, the designer integrates an understanding of:
—Lighting and mood
—Space and room composition
—Color, blending brightness and hues
—Artwork and even floral arrangements
—Texture, as in the furniture, wallpaper, and carpets
People consider Apple to be a "focused" company. After all, they have just a handful of products.
But each of these products blends a dizzying range of competencies.
