Pessimistic Time given Standard Deviation Solution

Follow our step by step solution on how to calculate Pessimistic Time given Standard Deviation?

FIRST Step Consider the formula

t p = 6 \cdot σ + t 0

Next Step Substitute values of Variables

∴

t p = 6 \cdot 1.33 + 2d

Next Step Prepare to Evaluate

∴

t p = 6 \cdot 1.33 + 2

Next Step Evaluate

∴

t p = 862272s

LAST Step Convert to Output's Unit

∴

t p = 9.98d

Go Pessimistic Time given Expected Time

t p = 6 \cdot t e - t 0 - 4 \cdot t m

Other formulas in Project Evaluation and Review Technique category

Go Mean or Expected Time

t e = \frac{t 0 + (4 \cdot t m) + t p}{6}

Go Optimistic Time given Expected Time

t 0 = (6 \cdot t e) - (4 \cdot t m) - t p

Go Most Likely Time given Expected Time

t m = \frac{6 \cdot t e - t 0 - t p}{4}

Go Standard Deviation of Activity

σ = \frac{t p - t 0}{6}

How to Evaluate Pessimistic Time given Standard Deviation?

Pessimistic Time given Standard Deviation evaluator uses Pessimistic Time = 6*Standard Deviation+Optimistic Time to evaluate the Pessimistic Time, The Pessimistic Time given Standard Deviation formula is defined as giving the maximum time required for the completion of a project under the worst conditions. Pessimistic Time is denoted by t_p symbol.
