The spike is used by the team to gain further understanding and collate information on an upcoming Product Backlog item that is lacking enough clarity.

Since they represent uncertainty in one or more potential stories, planning for both the spike and the resulting stories in the same iteration is sometimes risky. However, if it’s small and straightforward, and a quick solution is likely to be found, then it can be quite efficient to do both in the same iteration.

How to Enter a Spike
If the spike only takes, say, an hour or two, maybe we don’t need to track it in our ALM tool. If it’s larger than that, you should enter it into your backlog.
Time-box your Spikes
Teams should agree that every spike is, say, never more than 1 day of research. (For some teams this might be, say, 3 days, if that’s the common situation.) At the end of the time-box, you have to report out your findings. That might result in another spike, but time-box the experiments.
When To Use Spike?
Thus, you may consider a spike as an investment for a Product Owner to figure out what needs to be built and how the team is going to build it. The Product Owner allocates a little bit of the team’s capacity now, ahead of when the story needs to be delivered, so that when the story comes into the sprint, the team knows what to do.
What is spike in sprint planning?
Spikes should be estimated as in-Sprint tasks during Sprint Planning. The task’s duration should be spent researching and developing some ‘thing’ that can be delivered. That thing can be a working piece of software, workflow, documentation, etc. Ultimately the value from the spike is a direction or re-direction in the course of the feature. If the team estimated that a Spike takes four hours, then ONLY four hours should be spent researching or developing. Prototypes, Proof of Concepts (PoC), and Wireframes all fall into the classification of Spikes.

What does "spike" mean?
Seems to me that “spike” could potentially have two meanings: (a) a thin, pointed piece of metal, wood, or another rigid material (which, BTW, says nothing about it serving as an anchor); and (b) a sharp increase in the magnitude or concentration of something. Given that the two meanings are so divergent, why not use a different term that is more precise. I find it “funny” that methodologists — who should, if anything, be clear in the terms they use — persist in using words that are unclear. Why not call it “research”, “prerequisite”, or something like that?

The term spike comes from Extreme Programming (XP), where “A spike solution is a very simple program to explore potential solutions.” XP guru Ward Cunningham describes how the term was coined on the C2.com wiki: “I would often ask Kent [Beck], ‘What is the simplest thing we can program that will convince us we are on the right track?’ Such stepping outside the difficulties at hand often led us to simpler and more compelling solutions. Kent dubbed this a Spike. I found the practice particularly useful while maintaining large frameworks.”
Can you use spikes in research?
We’ve never used Spikes on our team. If Spikes are research, or trial-and-error, we simply create a Research task. And, by nature of trial-and-error, it’s possible that a “Spike” task could lead nowhere. So, to me, it would be overkill– and perhaps improper– to point out Spikes. If a task needs research time, we add that to the task at hand.
