Often a system that is hard to manage is described as fragile since the smallest change can have dire consequences on the system's functionality.

-===== Software Manageability Issues =====
-[[dido:public:ra:1.4_req:2_nonfunc:08_manageability | Return to the Top]]
-Over the last few decades, many advances have been made in terms of [[dido:public:ra:xapend:xapend.a_glossary:o:oss]] which has to change the way that software was developed, released and used. During this same time period, the traditional [[dido:public:ra:xapend:xapend.a_glossary:w:waterfall]] of System and software development has also been largely supplanted with the [[dido:public:ra:xapend:xapend.a_glossary:a:agile]]. Many of these changes also have to do with the evolution of systems (or projects) from being [[dido:public:ra:xapend:xapend.a_glossary:g:greenfield]] to [[dido:public:ra:xapend:xapend.a_glossary:b:brownfield]] development and from a "build the world" attitude towards "integrate and glue the world" mindset.
-Successful OSS development and adoption not only has to produce products which are solid, strong and robust but also must meet the needs of a [[dido:public:ra:xapend:xapend.a_glossary:c:coi]] that has coalesced around a single minded, purpose built, functionality (i.e., Apache Tomcat application server, PostgreSQL Database, Node.js an asynchronous event-driven JavaScript runtime, [[dido:public:ra:xapend:xapend.a_glossary:d:docker]] containerized apps, Kubernetes orchestration engine for containers, etc.). Many of the OSS products are part of many of the successful projects today.
-However, its not good enough to just write software and make it publicly available. At the heart of these successful efforts are the well governed, focused, supporting CoIs. There is a desire from almost all systems (or projects) to join the OSS trend but unfortunately, the need for strong governance and rigorous methodology is minimized or skipped in the name of expediency. Fortunately, there is an organization which can help with this called [[https://todogroup.org/about/ | Talk Openly Develop Openly (TODO)]] (not to be confused with a ''to-do'').
-TODO organization, though focused on OSS, has written a series of white papers that are well worth studying and using even it your system (or project) is not OSS. One of these papers which is particularly germane to Software Manageability is __Tools for managing open source programs__ ((__Tools for managing open source programs__, Talk Openly Develop Openly (TODO), Accessed 20 July 2020, [[https://todogroup.org/guides/management-tools/]]
-)). It is beyond the scope of this document to try to recreate the full content of this white paper. It does present a list of many of the tools available for managing software and how to use them. Here is the table of content from the document:

-^ **Health Monitoring, Logging, and Alerting**  | Although there are currently no [[dido:public:ra:xapend:xapend.a_glossary:d:dds|DDS]] standards for that directly supports System Monitoring, each of the DDS Vendors have sets of tools which can be used for that purpose. These tools include <WRAP>
-  * Development and troubleshooting including specialized network sniffers, modeling tools, and code generators
-  * System monitoring and administration including terminals, shared memory management tools, recorders and replayers
-  * Functional, systems and performance testing
-  * Federated [[dido:public:ra:xapend:xapend.a_glossary:d:discovery|Discovery]]
-  * Bridges to other [[dido:public:ra:xapend:xapend.a_glossary:m:mom]] products
-  * Topic aggregators

-^ **Configuration and Control**                 | DDS uses a standardized Discovery process which eliminates most of need for configuration. Some [[ddsf:private:cookbook:06_append:05_vendors | DDS Vendors]] offer specialized or advanced tools that aid in tuning DDS configurations and discovering performance issues|

For example, adding or removing fields in a [[dido:public:ra:xapend:xapend.a_glossary:d:datastructure]], changing the basic type from an int16 to an int32, etc. |
-^ **Asset Discovery and Inventory**             | DDS automatically registers all [[dido:public:ra:xapend:xapend.a_glossary:d:data_writer | Data Writer]] and [[dido:public:ra:xapend:xapend.a_glossary:d:data_reader | Data Reader]] allowing them to be discovered. It is possible|
