Module 5: Phase Management - Construction


Module 5 objectives

Module 5 Objectives

As a project progresses through phases and iterations, Describe the changing emphasis of Project Management by:

  • Understanding Construction objectives, milestones, and evaluation criteria.

  • Understanding principal Construction activities and artifacts and their uses.

  • Discussing team considerations regarding building the product.


Construction

Construction

Primary Objectives:

  • Minimizing development costs by optimizing resources and avoiding unnecessary scrap and rework

  • Achieving adequate quality as rapidly as practical

  • Achieving useful versions (alpha, beta, and other test releases) as rapidly as practical

    Essential Activities:

  • Resource management, control, and process optimization

  • Complete component development and testing against evaluation criteria

  • Assessment of product releases against acceptance criteria of the vision


Entering construction

Entering Construction

  • Major project risks have been mitigated, and the architecture is established on a firm foundation during Elaboration.

  • The tone of the project changes from engineering to production.

    • You know what you need to do (most of the invention was achieved and uncertainties were removed).

    • Staffing is increased.

    • Planning is aimed at efficiency and quality.


Construction considerations

Construction Considerations

  • Phase Focus

  • Resource management control and process optimization

  • Complete component development

  • Assess product against acceptance criteria and vision


Construction considerations1

Construction Considerations

  • Measurements

  • Progress90%

  • Expenditures (rate)High

  • StaffingSteady

  • StabilityModerate

  • Modularity<25%

  • AdaptabilityBenign

  • MaturityUsable


Rework in the iterative lifecycle

Rework in the Iterative Lifecycle

Extensive rework during Construction is avoided through solidifying the architecture in the Elaboration phase.

  • Too much rework

    • Gold plating

    • Unstable requirements

    • Not enough focus on cost and schedule

  • Too little rework

    • Excessive schedule pressure

    • Poor quality testing

    • Perception of rework as incompetence or failure

Importance of testing a manager s perspective

Importance of Testing: A Manager’s Perspective

  • Tests represent a part of the exit criteria for phases.

  • Tests provide some risk mitigation.

  • Tests of executable code provide quantifiable progress.

  • Test results provide quality measurements.

Construction evaluation criteria

Construction Evaluation Criteria

  • Is this product baseline mature enough to be deployed in the user community?

  • Is this product baseline stable enough to be deployed in the user community?

  • Are the collateral artifacts ready for transition to the user community?

  • Are actual resource expenditures versus planned expenditures acceptable?


Construction phase management issues

Construction Phase Management Issues

  • Project not converging

  • Forgetting about new risks


Construction phase recommendations

Construction Phase Recommendations

  • Each release provides:

    • A sense of accomplishment to developers

    • A point of control to managers

    • Reassurance to customers and other stakeholders

  • Never throw a release at a customer without preparation

    • Set expectations

    • Spend time with the customer

  • Adhere to the release schedule, shifting functionality rather than schedules

    • But beware of the snowplow effect, where everything gets pushed to the end of the schedule


Discussion characteristics of construction

Discussion: Characteristics of Construction

  • What are expected characteristics of the project during Construction?

  • What are activities that need emphasis during Construction?


Module 5 review

Module 5 Review

  • The main objective of Construction is to build the product.

    • Avoid rework by solidifying architecture in Elaboration

    • Never throw a release at a customer without preparation

    • Test each iteration for functionality and performance

  • Essential artifacts are:

    • The system
