Nesting Easter eggs show each layer of the process improvement architecture
One of my children owned a(Russian nesting doll) that is now somewhere in our attic. I was always struck how one piece fit within the other and how getting the assembly out of order generated a mess. I think I learned more from the toy than my children did. The matryoshka doll is a wonderful metaphor for models, frameworks, and methodologies. A model represents the outside shell into which a framework fits followed by the next doll representing a methodology placed inside the framework. Like models, frameworks, and methodologies, each individual doll is unique, but they are related to the whole group of dolls.
Models, the outside layer of our doll, are an abstraction that provides a rough definition of practices and inter-relationships needed by an organization to deliver aproduct or service. Models are valuable if they are theoretically consistent, fit the real world and have predictive power. All firms or groups use a model as a pattern to generate a structure. For example, the hierarchical corporation is a common model for commercial organizations (visualize an organization chart). The Capability Maturity Model Integration – Development (CMMI-DEV) is a model leveraged in many software development organizations. The CMMI provides a core set of practices that organizations have typically needed to deliver software. The CMMI defines an outline of what needs to be done but not how or in what order. The model that is chosen influences the models and methods that will be leveraged by different layers of the organization. For example, an organization using a lean start-up model for their corporate governance model might not see the CMMI-DEV model a viable for their development organization (we will discuss this common misperception later on the blog).
Frameworks, the next inner layer in our process architecture matryoshka doll, provide the structure needed to implement a model (or some part of the a model). Shifting the operational metaphor we are using for a moment to that of a skyscraper, the framework is the lattice like a frame that supports all of the componentsinthe superstructure. The Scaled Agile Framework Enterprise is a framework which leverages other frameworks and methods as tools to deliver value. SAFe defines the flow of work from an organization’s portfolio to the Agile teams that will develop and integrate the code. The Framework calls leverages other frameworks and methodologies such as DevOps, Scrum, Kanban and Extreme Programing.
Methods, nestled inside of frameworks, provide an approach to achieve a specific goal. In software development, methodologies define (or impose) a disciplined set of the processes so that developing software is more predictable and more efficient. The difference between Agile and heavier methods is the amount of structure that defined. Agile methods provide only just enough structure to allow the method embrace the principles stated in the Agile Manifesto. Extreme Programming is another software development methodology.
Each layer of our process architecture matryoshka doll is a step closer to a core set of steps and tasks. The doll metaphor is not perfect. Some small start-up organizations may not seem to need the structure of a framework or may even eschew a method until they grow. In an interview for the Software Process and Measurement Cast, Vinay Patankar, CEO of Process Street, said that as he and his partner began their start-up they used a code and fix approach, but growth forced the adoption of Agile as framework combined with Scrum and Extreme Programing (at least parts) as methodologies. A model provides an environment to implement a framework. You would not implement SAFe inside a waterfall model. Methodologies are the tools that translate a framework into something actionable. Without one or more or of thelayersin our doll, what remains of the doll might make a better rattle than a tool to deliver software.
FAQs
A methodology limits flexibility as it's based on a set of pre-defined rules and principles, while a framework involves several components which project managers can alter to match their needs. This makes frameworks a more suitable model when looking to customise or add to the project development and execution process.
What is the difference between framework and methodology and process? ›
While methodologies can be somewhat flexible, they will usually be fairly stringent in how they do things. Methodologies may not be as adaptive as frameworks, but they tend to offer a higher degree of control that can be better suited to large companies or projects that cannot tolerate risks.
Are model and methodology the same thing? ›
A model provides an environment to implement a framework. You would not implement SAFe inside a waterfall model. Methodologies are the tools that translate a framework into something actionable.
What is the difference between a theory framework and model? ›
Theoretical frameworks are often used to define concepts and explain phenomena. Using a model of this sort can be a way to structure a research paper or grant proposal. This guide will provide basic information about this concept, a list of commonly-used frameworks, and other tips for writing your paper or proposal.
What is models and methodology? ›
Methodology: Techniques, procedures, working concepts and rules how to solve a problem. Model: A representation and simplification of reality developed to convey information to a specific audience to support analysis, communication and understanding.
What is methodology in simple words? ›
A methodology is a system of methods and principles for doing something, for example for teaching or for carrying out research. [formal] Teaching methodologies vary according to the topic.
Is Agile a methodology or framework? ›
Rather, agile is a group of methodologies that demonstrate a commitment to tight feedback cycles and continuous improvement. The original Agile Manifesto didn't prescribe two-week iterations or an ideal team size. It simply laid out a set of core values that put people first.
What is framework example? ›
Some popular examples include Django and Ruby on Rails for web development, TensorFlow and PyTorch for machine learning, Unity and Unreal Engine for game development, and Spring and Hibernate for Java enterprise applications.
Is Scrum a framework or methodology? ›
Scrum is a management framework that teams use to self-organize and work towards a common goal. It describes a set of meetings, tools, and roles for efficient project delivery. Much like a sports team practicing for a big match, Scrum practices allow teams to self-manage, learn from experience, and adapt to change.
What is the difference between framework and model in business? ›
Models can be used for various purposes, such as performance analysis, simulation, or theoretical exploration. While frameworks focus on providing a structure for development, models focus on representing and analyzing systems.
Your methodology should begin by describing your research question and the type of data you used in answering it. You want to indicate why this type of data is appropriate, relevant, and important to the question being asked. You will then explain your process of data collection.
How do you create a model or framework? ›
Developing a Framework or Model of Change
- Analyzing Information About the Problem, Goals, and Factors Affecting Them.
- Establishing a Vision and Mission.
- Defining Organizational Structure and Operating Mechanisms.
- Arranging for Community Mobilizers.
- Developing and Using Strategic and Action Plans.
In general, a framework is a real or conceptual structure intended to serve as a support or guide for the building of something that expands the structure into something useful.
What is the difference between theory and methodology? ›
Theory is a set of propositions used to explain some phenomena, a narrative, and methodology is rules and procedures of research.
What is the difference between framework and methodology in scrum? ›
Scrum is more of a framework than a methodology, and it helps teams adhere to Agile principles and get stuff done. Scrum provides basic rules but doesn't prescribe how to do the work. It provides principles, values, rules, and some core structure but still leaves a lot undefined.
Is Agile a framework or methodology? ›
Agile Is Not a Methodology
Thanks to its universal values and principles, the Agile way of thinking is the basis of the Agile methods and frameworks we all use today. Agile methodologies help us develop the agility to adapt to the changing business environment and deliver high customer value faster.
What is model framework in research? ›
The framework is thus a structure that guides research, which is prior to it. Instead, a model is a conceptual and relational structure derived from research, that explains how the variables or factors that make a reality under particular conditions behave and relate. A model is thus a product of research.
Is research model and framework the same? ›
When a research is conducted or being planned the approach is basically defined by two key concepts. Those are the framework and the model. The framework gives the overall structure of the project while the model explores the specific methodology of the research.
