"a problem has different solutions on different days"

"Most of us would consider it unwise to do something before we are fully prepared; before the equipment is optimally in place and our workers well trained. But as the reader will discover, that's the situation we found ourselves in. And in researching this book, we discovered that that is the situation leaders and organizations far from any battlefield face every day.
...
The Task Force hadn't chosen to change; we were driven by necessity. Although lavishly resourced and exquisitely trained, we found ourselves losing to an enemy that, by traditional calculus, we should have dominated. Over time we came to realize that more than our foe, we were actually struggling to cope with an environment that was fundamentally different from anything we'd planned or trained for. The speed and interdependence of events had produced new dynamics that threatened to overwhelm the time-honored processes and culture we'd built.
.
Little of our transformation was planned. Few of the plans that we did develop unfolded as envisioned. Instead, we evolved in rapid iterations, changing—assessing—changing again. Intuition and hard-won experience became the beacons, often dimly visible, that guided us through the fog and friction. Over time we realized that we were not in search of the perfect solution—none existed. The environment in which we found ourselves, a convergence of twenty-first century factors and more timeless human interactions, demanded a dynamic, constantly adapting approach. For a soldier trained at West Point as an engineer, the idea that a problem has different solutions on different days was fundamentally, disturbing. Yet that was the case."
