It may appear contradictory to all that prepping stands for, but improvising is useful and downright necessary since no one can fully predict how long SHTF will last and what dangers lurk in that scenario. However, improvising should never take the place of prepping as this remains the best way to survive a disaster.

Prepping saves you the time it takes you to hatch an improvised plan. It also smooths out the creases that can otherwise make it harder to address the problem at hand. Without prepping, the odds are stacked against you no matter how resourceful you are.
This is not to say that improvising has no place in the prepper mindset – far from it. Being able to think outside the box in the presence of danger is one of the most valuable skills a survivalist can possess. But improvising should not be your primary goal.

It's advisable that you use the right gear whenever possible, but in emergencies, you can improvise the following survival items to save your life:
It's important to be resourceful to be able to improvise in situations that are not covered by your survival plan. But improvising should not replace prepping because it greatly limits your options and curbs your ability to respond adequately to a disaster.
