Origins The concept of theories of change emerged from the field of program theory and
program evaluation in the mid 1990s as a new way of analyzing the theories motivating programs and initiatives working for social and political change. Its earlier origins can be traced to
Peter Drucker's articulation of
Management by Objectives, popularized in his 1954 book
The Practice of Management. Management by Objectives requires identifying higher-order Goals, and lower-order Objectives which, if achieved, are expected to result in the Goals being achieved. Theory of Change extends beyond Goals (commonly named
Outcomes in Theory of Change terminology) and Objectives to include Impact – the anticipated result of achieving stated goals. Theory of Change is focused not just on generating knowledge about whether a program is effective, but also on explaining what methods it uses to be effective. Theory of Change as a concept has strong roots in a number of disciplines, including
environmental and
organizational psychology, but has also increasingly been connected to
sociology and
political science. Within industrial-organizational psychology, Austin and Bartunek have noted that approaches to
organizational development are frequently based on more or less explicit assumptions about 1) the processes through which organizations change, and 2) the interventions needed to effect change.
Development in evaluation practice Within
evaluation practice, Theory of Change emerged in the 1990s at the
Aspen Institute Roundtable on Community Change as a means to model and evaluate comprehensive community initiatives. Notable methodologists, such as
Huey-tsyh Chen,
Peter Rossi,
Michael Quinn Patton,
Heléne Clark,
Carol Taylor Fitz-Gibbon, and
Carol Weiss, had been thinking about how to apply program theories to
evaluation since the 1970s. The Roundtable's early work focused on working through the challenges of evaluating complex community initiatives. This work culminated in a 1995 publication, 'New Approaches to Evaluating Comprehensive Community Initiatives'. and later of Theory of Change Online software.
Growing popularity In the 2010s, interest increased with some reviews commissioned by
Comic Relief in the UK, the
Department for International Development in the UK,
the Asia Foundation and
Oxfam Australia to name a few. The explosion of knowledge of the term, and demand for "theories", led to the formation in 2013 of the first non-profit dedicated to promoting and clarifying standards for Theory of Change. The Center for Theory of Change free of charge. The use of Theory of Change in planning and evaluation has increased among philanthropies, government agencies, development organizations, universities, international
NGOs, the
UN, and many other major organizations in both developed and developing countries. This has led to new areas of work, such as linking the Theory of Change approach to
systems thinking and complexity. Change processes are no longer seen as linear, but as having many feedback loops that need to be understood. Consequently, Theory of Change is strengthening monitoring,
evaluation and
learning. They are also helping to understand and assess impact in hard to measure areas, such as
governance, capacity strengthening and institutional development. Innovations continue to emerge.
Challenges Despite the growing ubiquity of Theory of Change, especially in the development arena, understanding of the approach and the methods necessary to implement it effectively are not uniform. In fact, there is evidence of some confusion about what the term 'Theory of Change' actually means; in some cases, what some program developers describe as a Theory of Change is, in essence, simply a
log frame, strategic plan or another approach that does not encompass the complexity of the Theory of Change approach. There is also inconsistent use of other common Theory of Change terminology (e.g., outputs, outcomes, impacts, etc.), which confounds effective Theory of Change design, evaluation, and learning. == Methodology ==
