Understanding the Development Hypothesis and Associated Logic Models

It is essential to understand the importance of the development hypothesis and the logic model in M&E. A sound and well-reasoned logic model is necessary for effective programming, as it describes the theory of change, logic, and causal relationships between the building blocks needed to achieve a long-term result. The logic model is a graphical depiction of the logical relationships between resources, activities, outputs, and outcomes. It is used to assess the "if-then" (causal) relationships between the elements of a program. A logic model is equivalent to a logframe, results framework, objective tree, theory of change, or development hypothesis. It is a critical tool for M&E, as it provides a framework for understanding how an intervention is intended to produce particular results. A well-reasoned results framework, or logframe, is essential for effective programming and M&E. It is based on an inter-related set of components, where one builds on the other. The logframe is the foundation for M&E, serving as a "flagging system" for management and evaluation. It helps managers achieve clarity and focus in an inherently complex environment. The development hypothesis is a critical component of the logic model, describing the theory of change, logic, and causal relationships between the building blocks needed to achieve a long-term result. It is based on development theory, practice, literature, and experience, and is country-specific. The development hypothesis explains why and how the proposed investments lead to achieving objectives. A result is a significant, intended, and measurable change in the condition of a customer, or a change in the host country, institutions, or other entities that will affect the customer directly or indirectly. The development hypothesis is used to identify the most ambitious result for which USAID, along with its partners, is willing to be held accountable. This result is referred to as the development objective. The development hypothesis is composed of four basic building blocks: input, development objective, intermediate result, and output. Input refers to the resources used to produce an output. The development objective is the most ambitious result for which USAID, along with its partners, is willing to be held accountable. Intermediate result refers to the events, occurrences, or conditions likely to result in the development objective. Output refers to the products or services produced as a result of internal activity.
