DDLC was initially synchronized with Waterfall and V model Waterfall Model V Model Sequential design process, which is seen as flowing steadily downwards through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance. Extension of the waterfall model, which demonstrates the relationships between each phase of the development life cycle and its associated phase of testing in a V-shape.

Synchronizing DDLC with sequential models of product development leads to critical challenges Less time, more tasks Completion of most of the tasks encapsulated in the DDLC during the testing and acceptance phase of the software development. Last minute updates Incorporation of last minute customer critical updates in multiple documents at a short notice in a short duration. On time translation Inadequate support from development team Selection of an appropriate translation technology, process, and resource to translate the documents prior to the release of the product. Absence of either any dedicated resources or time allocation to the developers for discussion with the documentation team.

Advent of Agile model minimized drawbacks of the sequential development models Incremental model of software development Customer satisfaction by rapid and continuous delivery of useful software Emphasis on people and communication instead of process and tools Frequent delivery of working software (weeks instead of months) Close and daily cooperation between business people and developers Continuous attention to technical excellence and good design Regular adaptation to changing circumstances and requirements Page 9 May 2015 Corporate Technology Unrestricted use only / Siemens AG 2015.

Projects started getting aligned gradually to Scrum model of development Scrum is an iterative and incremental Agile software model of development. Software is developed in incremental, rapid cycles resulting in small incremental releases with each release building on previous functionality.

Agile model of development also had its share of challenges in DDLC Usable Documentation Creating an usable documentation at the end of every sprint Inputs received at the end of every Sprint Completing the documentation of the feature within the same sprint of development in a short duration Non-finalized screenshots Capturing of the screenshots multiple times owing to repeated changes in the user interface Translation Translating documents during the development sprints Defect Tracking Ensuring that the release criteria board for software documentation is green Page 11 May 2015 Corporate Technology Unrestricted use only / Siemens AG 2015.

Lean software development is a translation of lean manufacturing and lean IT principles and practices to the software development Originally called just-in-time production Adapted from the Toyota Production System Value Value Streaming Understand how value is perceived by the customer What adds value to the customer Removes waste from end to end value streams Flow Flow cleanly from start to finish Perfection Pull Seek perfection through continual improvement Focus of simulation What pulls the customer Page 13 May 2015 Corporate Technology Unrestricted use only / Siemens AG 2015.

Case Study Eliminating waste Created a streamlined process of creating a UI message by eliminating a wastage of 47 % of the effort and time of all the stakeholders using value-stream mapping. Established the principles of passing a defect /test case on User Documentation on the basis of source language documentation. Established the process of effective creation and review of FDUD to reduce the number of review comments during the online review of the meeting with all the stakeholders.

What went well and what did not go well - Global responsibility of software documentation - Adherence to Lean model - Distribution and delegation of tasks - Introduction of processes and technology - Improvement of processes and technology - On-time delivery - Availability of multilingual documents globally Waterfall or V model: - Delay in delivering translated documents - Delayed review process - Time bound stress Lean model: - Time bound stress - Constant improvisation in processes to eliminate waste Page 23 May 2015 Corporate Technology Unrestricted use only / Siemens AG 2015.
