PROJECT, PROGRAMME, AND PORTFOLIO MANAGEMENT

Enterprises increasingly accomplish strategic change through temporary initiatives, yet delivering a specified output within an approved budget does not guarantee useful, equitable or durable results. This chapter critically examines project, programme and portfolio management as interdependent mechanisms for selecting investments, organizing temporary work and realizing benefits within continuing enterprise systems. A transparent, purposive synthesis combines foundational scheduling research, theories of temporary organization, governance, agency and stewardship, real-options reasoning, contemporary empirical project scholarship, and official PMI and ISO guidance. Twelve approved domains address authorization and selection; life cycles and governance; scope, dependencies, schedules and cost; uncertainty and stakeholders; teams and procurement; predictive and adaptive delivery; benefits evaluation; and digitally assisted project control. Official documentation of Rwanda’s Digital Acceleration Project and the United Kingdom’s Crossrail programme supports a comparative analysis that distinguishes policy intentions from independently established outcomes. An explicitly constructed Kigali university-service transformation project provides an auditable charter, work breakdown structure, critical-path network, cost baseline, earned-value measures, decision log, risk register and benefits appraisal. The central argument is that project success should be evaluated as a conditional relationship between legitimate strategic selection, feasible delivery, accountable governance and observed post-handover value, rather than a simple function of time, cost and scope. The integrated framework is a scholarly synthesis proposed for testing, not a newly validated causal model.
