time deviation
10
DescriptionPercentage deviation in time respect the estimated date, for completion of milestones and / or project
Type Schedule
Measurement objective
Are we accomplished the scheduled dates?
Unit Percentage
Data sourceSchedule / Project Plan
ProposalCollection method
Counting
Frequency Weekly / Biweekly / Monthly Goal 0%
Formula (real date – estimate date) / estimate date
Analysis criteria
• < 0, project is executing below the planning
• = 0, project is executing on time
• > 0, project is executing with deviation
Variations Counting the delayed days in absolute terms
time deviation
11
post-production defects
12
post-production defects
DescriptionDefects reported by the customer once the product has been delivered
TypeProduct quality
Measurement objective
Have we delivered the product without defects and / or mistakes?
Unit Defects
Data source Client’s incidentsCollection method
Counting
Frequency Monthly Goal 0
Formula N.A.
Analysis criteria
= 0, product has no detected defects
> 0, product was delivered with defects, and corrections have not an estimated/planned effort
Variations Counting effort to correct defects (hours, days)
13
effort deviation
14
Description
Percentage deviation in hours/date respect the estimated effort, for completion of tasks, milestones and / or project
Type Cost
Measurement objective
Are we performing the project with over-effort?
Unit Percentage
Data sourceSchedule / Project Plan
Effort estimationCollection method
Effort timesheet
Frequency Weekly / Biweekly / Monthly Goal 0%
Formula (real hours/days – estimate hours/days) / estimate hours/days
Analysis criteria
< 0, project is executing below the estimation
= 0, project is executing according to the estimation
> 0, project is executing with over-effort
Variations Counting the over-effort (hours/days) in absolute terms
effort deviation
15
change requests
16
DescriptionChange request from customers (external) and project team (internal)
TypeProduct stability
Measurement objective
Have we kept the scope and / or initial estimates of the project?
UnitChange requests
Data sourceChange request from customers and project team
Collection method
Counting
Frequency Monthly Goal 0
Formula N.A.
Analysis criteria
= 0, product has no change requests
> 0, product has change requests that could impact project parameters (size, effort, dates)
VariationsCounting effort to implement change requests (hours, days)
Comparing changed requirements vs. initial requirements
change requests
17
non-conformities
18
DescriptionDefects, errors and non conformities detected by project team, before delivery of the products to the client
TypeProduct quality
Measurement objective
Are we performing our processes and developing products as established?
Unit Defects
Data sourceQuality audits / Test Plans / Identified defects
Collection method
Counting
Frequency Monthly Goal 0
Formula N.A.
Analysis criteria
= 0, there have not identified defects or non conformities
> 0, there have identified defects or non conformities, and corrective actions has an impact in the project parameters
VariationsCounting effort to correct defects (hours, days)
Categorize them by project phase, defect type, etc.
