Infrastructure assessments are usually implemented as a complex project and require considerable effort and time. The key point for such projects is a methodology; a clear explanation of all aspects of data collection, analysis, and interpretation of results is crucial.

This article is focused on the methods to accelerate and improve the process of diagram development.
Case study #2
Telecom Company asked the system Integrator to sell 600TB of space to store backup copies of data. Unfortunately, the budget for that is very limited. Integrator hopes for a long-term relationship with the customer and therefore decided to use Human Defined Services approach to solving the situation the most efficient way.
Case study #1
DBAs and system administrators complained that storage provisioning takes too long. Storage administrator decided to find the answer for the key question “How to decrease the provisioning time?”
“Designers work iteratively to test their ideas and improve them throughout the entire development process. Making an idea tangible from an early stage through cheap mock-ups helps save resources and can minimize risk. Few advices for a solutions design prototyping here.
Case study #3
A medium size software development company had its own datacenter. Accidentally, a fire destroyed the data center. Fortunately backup of the important data was in the safe place. How the company should restore data access?
Diagrams are needed to transfer new information to the audience in visual form. All graphics consist of both real data and decoration.
How to balance data and decarations on diagrams?
Service Design and problem resolution always must be based on the information about the system and environment. How to get such information if we don’t know the exact answer?
As an urban planning or design of consumers’ goods, IT architecture can be elegant or ugly, functional or wasteful. It can tell us, “Our organization is very pragmatic” or vise verse “We have too much money to spend them smartly”. Different people with their preferences, visions and practical reasons usually form the architecture over the years. Is it possible to keep and control the beautiful style of architecture for a long time?
Wikipedia describes an Issue tree as a graphical breakdown of a question that dissects it into its different components vertically, and that progresses into details as it reads to the right.
Issue trees are useful in problem-solving to identify the root causes of a problem as well as to find potential solutions.
In IT every person plays two roles – Provider and Consumer. For example application administrator provide users’ access to the application. At the same time, he consumes services provided by DBAs, system, network and storage administrators. And so on… It’s a chain.
Value flow illustrates dependencies between Consumers and Providers in the chain of service delivery process. It defines what job has to be done on each chain link, reveal qualitative and quantitative metrics for sub-services’ success and describe incoming services.
In that post we discuss about why Service Designer needs heuristic tools?
Complexity of services has to be explored and can be exploited. In the very begining we need to understand how complex the system is and place it in the continuum from ordered to unordered state. Cynefin is the framework that helps to do that.
The primary purpose of services is to get consumer’s job done well. Outcome-driven service is an approach that shifts the focus away from the service solution back to a job’s outcome and satisfaction in each step of execution.
What are the most important characteristics of services?
During all phases of Service Design, several aspects of services have to be considered. Some of them direct the way of the design. Other characteristics should be changed to optimize the service or resolve the problem.
What are the Principles of Service Design?
Experts lay out five general principles of Service Design:
- User Centered
Let’s consider them in details.
Before we start a discussion about Service Design, we have to define the meaning of the main terms. What are Services? What is a Service Design?
Every complex structure needs a reference frame to be measured and controlled. Information Technologies also require a common coordinate system that on the one hand has to be simple and clear for easy usage and on the other hand comprehensive enough to describe complex projects and approaches. The best candidate is the frame of reference based on three dimensions: People, Processes and Technologies (PPT).
