Crashing, Fast Tracking, Scope Trimming & Factors influencing Projects

Schedule Compression Techniques

Schedule compression techniques are used to bring project back on Planned Schedule (Schedule Baseline) by Fast Tracking or Crashing the Schedule for the Remaining Work

Crashing
  • If schedule compression is required, then critical path activities are adjusted by adding or removing some activities from it without changing the actual project scope.
  • Trades Time for Money; Increases Costs and, possibly, Risks
Fast Tracking
  • Performing activities planned in series, in parallel
  • Often results in Rework (Cost), hiring additional Resources (Cost), increasing Risk and requiring more attention to Communication
Scope trimming
  • Scope trimming is removing critical path activities. It’s basically cutting activities from critical path to return the project on track to complete it timely.

Environmental factors influencing Projects

Two major categories of influences which impact projects are Enterprise Environmental Factors (EEFs) and Organizational Process Assets (OPAs).

Organizational Process Assets (OPA)

Processes, Policies, Procedures, Corporate Knowledge Base

OPA are either the Company Policies, SOPs, etc. within which the Project is to be executed or the Company’s databases of experience and knowledge

Enterprise Environmental Factors (EEF)

EEF add Strength or Weakness to the Project. They are Force Multipliers or Dividers, and can be Internal or External to the Organization executing the Project

Environments/Influences

Internal Enterprise Environmental Factors (Internal EEF)
  1. Organizational Culture, Structure, & Governance

Vision, mission, values, beliefs, cultural norms, leadership style, hierarchy and authority relationships, organizational style, ethics, and code of conduct

  1. Infrastructure

Existing facilities, equipment, organizational tele-communications channels, information technology hardware, availability, and capacity

  1. IT Software

Scheduling software tools, configuration management systems, web interfaces to other online automated systems, and work authorization systems

  1. Resource Availability

Contracting and purchasing constraints, approved providers and subcontractors, and collaboration agreements

  1. Employee Capability

Existing HR expertise, skills, competencies, and specialized knowledge

External Enterprise Environmental Factors (External EEF)
  1. Marketplace Conditions
  2. Social & cultural Influences and Issues

Political climate, codes of conduct, ethics, and perceptions

  1. Legal Restrictions
  2. Commercial Databases

Benchmarking results, standardized cost estimating data, industry risk study information, and risk databases

  1. Academic Research
  2. Government or industry Standards
  3. Economic Considerations

Currency exchange rates, interest rates, inflation rates, tariffs, and geographic location

  1. Physical Environmental Elements
Important Terms in Network Diagram and Critical Path Method
Network Path

A Sequence of Activities connected by Logical Relationships in a Schedule NWD.

Critical Path

The Network Path of the longest Duration. It dictates the Project Duration

Early Start Date

The earliest possible time when a schedule activity can start

Early Finish Date

The earliest possible time when a schedule activity can finish

Late Start Date

The latest possible when a schedule activity can start without affecting the project completion date

Late Finish Date

The latest possible point when a schedule activity can finish without affecting the project completion date

Node

A point at which dependency lines connect on an NWD/CPM
