| Abstract | Several years ago the U.S. Department of Defense created its Defense Science Board Task Force on Military Software, chaired by Dr. Frederick Brooks, to provide recommendations on how best to solve the problem of escalating military software acquisition costs. The final report (reference 2) of this task force was completed in September 1987, and was widely distributed. Among its several major conclusions are the following:DoD Directive 5000.29 and STD 2167 codify the best 1975 thinking about software, including a so-called 'waterfall' model calling for formal specification, then request for bids, then contracting, delivery, installation, and maintenance. In the decade since the waterfall model was developed, our discipline has come to recognize that setting the requirements is the most difficult and crucial part of the software building process, and one that requires iteration between the designers and users. In best modern practice, the early specification is embodied in a prototype, which the intended users can themselves drive in order to see the consequences of their imaginings. Then, as the design effort begins to yield data on the cost and schedule consequences of particular specifications, the designers and the users revise the specifications.Directive 5000.29 not only does not encourage this best modern practice, it essentially forbids it. We recommend that it be revised immediately to mandate and facilitate early prototyping before the baseline specifications are established.DoD STD-2167 likewise needs a radical overhaul to reflect best modern practice. Draft DoD STD 2167A is a step, but it does not go nearly far enough. As drafted, it continues to reinforce exactly the document-driven, specify-then-build approach that lies at the heart of so many DoD software problems. |

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.
