Software Operability: a DevOps Cornerstone

DevOps have helped organisations to re-align their business and technology goals towards sustainable delivery of valuable, working software. You need to understand exactly where processing delays occur so you can troubleshoot more quickly and resolve the bottlenecks. You can do this using correlation IDs, near-unique identifiers that you inject at the edge of the system and then pass down through downstream components. As the number of processing nodes—servers, containers, IoT devices, availability zones—increases, you need to be able to reconstruct a request as an execution trace across multiple nodes. Perhaps one or more nodes are faulty or misconfigured, such as having the wrong version of a container image deployed.

Operability is the ability to keep a piece of equipment, a system or a whole industrial installation in a safe and reliable functioning condition, according to pre-defined operational requirements. ThePD has been developing the Preferred Project Definitions based on the actual project execution and operation experiences and knowledge with the Project Language, and sharing with you daily basis.

If the language uses a different writing system it is almost impossible if no translation tools are available. The U.S. government is making an effort to overcome the nation’s lack of public safety interoperability. The Department of Homeland Security’s Office for Interoperability and Compatibility (OIC) is pursuing the SAFECOM[16] and CADIP and Project 25 programs, which are designed to help agencies as they integrate their CAD and other IT systems. Types of interoperability include syntactic interoperability, where two systems can communicate with each other, and cross-domain interoperability, where multiple organizations work together and exchange information.

  • If data is interpreted differently, collaboration is limited, takes longer and is inefficient.
  • After the doubts and reservations of all members are addressed, the resulting common document is endorsed as a common standard.
  • In addition, standards, such as Open Archives Initiative Protocol for Metadata Harvesting, Resource Description Framework, and SPARQL, have emerged that also help address the issue of search interoperability related to web resources.
  • Since 2007, I have treated logging as a rich trace of application behavior, using unique identifiers such as an enum to represent distinct states that I also call event IDs.
  • This technique is particularly powerful when teams collaborate on the conditions for “healthy” and “unhealthy.” Why does component X need to see that external service?

In any case, it is essential to treat software operability as a ‘first-class citizen’ of a product and to treat (you can find here the entire presentation) ‘ops’ as a high-skill field. However, the path to good operability could require some changes in how the whole team approaches product development. For example, a good starting point might be to avoid the historical distinction between functional and non-functional requirements.

Dictionary Entries Near operable

Specifically related to web-based search, the challenge of interoperability stems from the fact designers of web resources typically have little or no need to concern themselves with exchanging information with other web resources. Federated Search technology, which does not place format requirements on the data owner, has emerged as one solution to search interoperability challenges. In addition, standards, such as Open Archives Initiative Protocol for Metadata Harvesting, Resource Description Framework, and SPARQL, have emerged that also help address the issue of search interoperability related to web resources.


Interoperability can have a significant impact on the organizations concerned, raising issues of ownership (do people want to share their data? or are they dealing with information silos?), labor relations (are people prepared to undergo training?) and usability. In this context, a more apt definition is captured in the term business process interoperability. If two or more systems use common data formats and communication protocols then they are capable of communicating with each other and they exhibit syntactic interoperability. Low-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all the communicating systems. This technique is particularly powerful when teams collaborate on the conditions for “healthy” and “unhealthy.” Why does component X need to see that external service? You very soon discover interesting runtime dependencies through the process of defining the health-check logic.


For example, purchases sometimes need to be completed within a time limit for security reasons. This guideline covers the necessity of making core website functionality available via a keyboard in addition to other means (e.g. mouse), so that users that rely on keyboard controls can access them. At Codemotion Milan 2018, Marco Abis discussed some suggestions that are summarised in the following slide.

Microsoft was ordered to disclose complete and accurate interface documentation, which will enable rival vendors to compete on an equal footing (the interoperability remedy). As of June 2005, the Commission is market testing a new proposal by Microsoft to do this, having rejected previous proposals as insufficient. In your efforts to meet the needs of the primary users of your systems, you sometimes forget to meet the needs of secondary or internal users such as testers, release engineers, and ops people, which is a problem. If your software is difficult to test, difficult to deploy, and difficult to operate, you risk losing money or reputation fighting the software to resolve the problem when there is a failure of some kind. As software systems become more distributed and interconnected, you need to ensure that the software works well when operating live in production—what I call software “operability”—and you need to be able to observe its behavior. These examples are programmatically compiled from various online sources to illustrate current usage of the word ‘interoperability.’ Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors.

Examples of operable in a Sentence

They also include the software in the computers which control the way the engine changes its speed in response to the actions of the pilot in selecting a start, selecting different idle settings and higher power ratings such as take-off, climb and cruise. The engine has to start to idle and accelerate and decelerate within agreed, or mandated, times while remaining within operating limits (shaft speeds, turbine temperature, combustor casing pressure) over the required aircraft operating envelope. In a computing systems environment with multiple systems this includes the ability of products, systems and business processes to work together to accomplish a common task such as finding and returning availability of inventory for flight. Operability is an ability of the process or plant that has the capacity and flexibility to achieve a range of operating conditions safely, reliably, profitably and with good dynamic performance and product quality. The Operability ensures to keep the equipment, system or unit and plant in a safe and reliable functioning condition that is pre-defined operational requirements.

Data exchange between applications, databases and IT systems is crucial for the growth of modern technology, such as the IoT. Approaches to improving or achieving interoperability include conducting compatibility tests, engineering products with a common standard and using the same technology, coding language or syntax across multiple systems when appropriate. Because first responders need to be able to communicate during wide-scale emergencies, interoperability is an important issue for law enforcement, fire fighting, emergency medical services, and other public health and safety departments. Agencies tried to bridge this isolation with inefficient, stop-gap methods while large agencies began implementing limited interoperable systems.

More from Merriam-Webster on interoperability

Even without the negative semantic connotation of the term ‘non-functional requirements‘, it is more accurate to speak in terms of ‘end-user features‘ and ‘operational features‘, giving equal importance to both. Just as it is important to be able to check and test user stories – “as a customer, I want to buy a product“, for example – it must be possible to verify and test the user story “as ops, I want to switch a feature” in the same way. In the upcoming Codemotion conference, to be held online on October 20, 21, and 22, 2020, the topic of DevOps will be addressed widely in numerous talks (you can find the schedule here). Not for the first time, our speakers will retrace some salient features of the DevOps culture, and the importance of software operability.


These approaches were inadequate and, in the US, the lack of interoperability in the public safety realm become evident during the 9/11 attacks[13] on the Pentagon and World Trade Center structures. Further evidence of a lack of interoperability surfaced when agencies tackled the aftermath of Hurricane Katrina. After the doubts and reservations of all members are addressed, the resulting common document is endorsed as a common standard. This document may be subsequently released to the public, and henceforth becomes an open standard. It is usually published and is available freely or at a nominal cost to any and all comers, with no further encumbrances. Interoperability (pronounced IHN-



-tee) is the ability of different systems, devices, applications or products to connect and communicate in a coordinated way, without effort from the end user.

Provide helper endpoints for services such as databases or queues that have no native HTTP capability. This lets you wire up a standard environment dashboard really easily, showing the health of all components at a glance. The Run Book operability dialog sheet technique works best when the dev/delivery team takes the lead on defining the initial set of operational features, because the team typically has to reach out to more operations-focused teams to fill in the details.
