| Abstract | The fragility created by hierarchical organizational constructs crosses over into the design of many large scale IT systems that are distributed across an enterprise. This means, that for these systems, end-to-end system design comes from the top down, creating a situation in which all fragility rises up to the largest scales of the system; this is a result of these systems being centrally controlled, often at the top of a hierarchy. In order for enterprise systems such as these to augment or repair themselves, they must undergo a catastrophic, enterprise-wide failure and be reengineered, once again by top-down direction [1]. This is the opposite of resilient system design and represents a situation where federal IT can be very inefficient. The current climate in the US of proactive and aggressive infrastructure consolidation via the Federal Data Center Consolidation Initiative (FDCCI) and the National Defense Authorization Act (NDAA) only serves to further incentivize system designers to construct extremely fragile systems at both the application and infrastructure layers. This fragility puts these systems at greater risk for enterprise failure. An example of a critical federal enterprise IT system's design and resulting fragility when perturbed (i.e., via consolidation and modernization) will be examined in this paper. Engineering guidelines from a complex systems perspective will be recommended to counter this resulting fragility. These guidelines will be from both an IT and government policy point of view and are generalized for applicability to systems engineering outside the scope of just IT systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
