<blockquote>"Program Evaluation and Review Technique (PERT) offers an effective way to convert estimates into probability distributions suitable for the business team and for the managers."

<p><strong>O : Optimistic Estimate.</strong><br>Everything goes as planned, nothing as come into the way.
</p>
<p><strong>N : Nominal Estimate.</strong><br>The value with the highest probability.
</p>
<p><strong>P : Pessimistic Estimate.</strong><br>Everything goes wrong, very low percentage of chance to append.
</p>
<p>With these 3 values it’s possible to describe the probability distribution of the task with the following formula:</p>
<p><code><strong>µ = (O + 4N + P) / 6</strong></code></p>
<p>Mu (µ) gives us the expected duration of the task. But this is just an average based on some coefficients and cannot be used as a deadline, it is a hint. Moreover the pessimistic estimate high value increase this average.</p>
<p><code><strong>σ = (P – O) / 6</strong></code></p>
<p>Sigma (σ) represents the standard deviation of the task. It is a measure to specify how uncertain the task is.<strong>The higher this value, the higher the risk.</strong></p>
