Variation Management Protocol (VMP)

Variation Management Protocol (VMP) is utilized for quantification of

Scope Variation, Time Variation, and Cost Variation corresponding to the Baseline Scope, Baseline Time (Project Schedule), and Baseline Cost (Project Budget).

Developed at Stoneboy, VMP is a comprehensive methodology which utilizes calculus, and advanced data analytics for construction project reporting and analysis. A potential game changer in the field of Variation Analysis, Impact Analysis, Construction Dispute Management (CDM) / Construction Claims Management; VMP is a spin off of Stoneboy's holistic project data management approach, and its unique Project Data Management service vertical.

SFM: Key Concepts

Project Elements (in order of precedence):

•  S-T-C

•  Scope → Time → Cost

Variation Event

• An event which has exception, or exclusion from existing

   (as-planned / baseline / contract) Scope → Time → Cost

• A variation event can result in an extension, or reduction of existing

   (as-planned / baseline / contract) Scope → Time → Cost.

Change Instance

•  Change Orders, Change Orders (Proposed), Change Orders (Rejected),

    Change Orders (Revoked), Change Directives, Site Instructions, Field Orders,


PTO (Process & Transaction Overhead)

•  Such as delay in approval, process bottlenecks, etc.

Scope Variation

•  Variation in Scope Model, or Scope

•  Positive Scope Variation (scope extension), or Negative Scope Variation

    (scope reduction)

• Causes of Scope Variation

○ Change in charter

○ Change in design

○ Change in other project objectives

○ Change in timeline

○ Change in budget / value engineering

○ Corrective action for errors & omissions

○ Unforeseeable conditions, Unforeseen conditions

○ Force Majeure events, Acts of Nature, Acts of God

○ Change in means & methods


Time Variation

• Variation in Time Model, or Schedule

• Positive Time Variation (time extension), or Negative Time Variation

   (time reduction)

• Causes of Time Variation

○ Scope Variation

○ Change Instances

○ PTO (Process & Transaction Overhead)

○ Late Start, or consumption of float

○ Late finish, or consumption of float

○ Loss of Productivity

○ Procurement

○ Subcontractor Performance


Cost Variation

• Variation in Cost Model, or Budget

• Positive Cost Variation (cost extension), or Negative Cost Variation

    (cost reduction)

• Causes of Cost Variation

○ Scope Variation

○ Time Variation
