The Timeboxing Process Model for Iterative Software Development
The Timeboxing Process Model for Iterative Software Development Pankaj Jalote Department of Computer Science and Engineering Indian Institute of Technology Kanpur – 208016; India Aveejeet Palit, Priya Kurien Infosys Technologies Limited Electronics City Bangalore – 561 229; India Contact: [email protected] ABSTRACT In today’s business where speed is of essence, an iterative development approach that allows the functionality to be delivered in parts has become a necessity and an effective way to manage risks. In an iterative process, the development of a software system is done in increments, each increment forming of an iteration and resulting in a working system. A common iterative approach is to decide what should be developed in an iteration and then plan the iteration accordingly. A somewhat different iterative is approach is to time box different iterations. In this approach, the length of an iteration is fixed and what should be developed in an iteration is adjusted to fit the time box. Generally, the time boxed iterations are executed in sequence, with some overlap where feasible. In this paper we propose the timeboxing process model that takes the concept of time boxed iterations further by adding pipelining concepts to it for permitting overlapped execution of different iterations. In the timeboxing process model, each time boxed iteration is divided into equal length stages, each stage having a defined function and resulting in a clear work product that is handed over to the next stage. With this division into stages, pipelining concepts are employed to have multiple time boxes executing concurrently, leading to a reduction in the delivery time for product releases. -

Multi Objective Analysis for Timeboxing Models of Software Development
MULTI OBJECTIVE ANALYSIS FOR TIMEBOXING MODELS OF SOFTWARE DEVELOPMENT Vassilis C. Gerogiannis and Pandelis G. Ipsilandis Department of Project Management, Technological Education Institute of Larissa, Larissa, Greece Keywords: Software Project Management, Iterative Development, Timeboxing, Project Scheduling, Linear Programming, Multi-Objective Optimization. Abstract: In iterative/incremental software development, software deliverables are built in iterations - each iteration providing parts of the required software functionality. To better manage and monitor resources, plan and deliverables, iterations are usually performed during specific time periods, so called “time boxes”. Each time box is further divided into a sequence of stages and a dedicated development team is assigned to each stage. Iterations can be performed in parallel to reduce the project completion time by exploiting a “pipelining” concept, that is, when a team completes the tasks of a stage, it hands over the intermediate deliverables to the team executing the next stage and then starts executing the same stage in the next iteration. In this paper, we address the problem of optimizing the schedule of a software project that follows an iterative, timeboxing process model. A multi objective linear programming technique is introduced to consider multiple parameters, such as the project duration, the work discontinuities of development teams in successive iterations and the release (delivery) time of software deliverables. The proposed model can be used to generate alternative project plans based on the relative importance of these parameters. 1 INTRODUCTION team of experts is usually assigned to each stage, i.e., a team for a stage performs only the activities In iterative and incremental development, software for that stage. -
ASSESSING KANBAN FITMENT in the FLUID and FAST-PACED WORLD of SOFTWARE DEVELOPMENT - Vikram Abrol, Ketan Shah
WHITE PAPER ASSESSING KANBAN FITMENT IN THE FLUID AND FAST-PACED WORLD OF SOFTWARE DEVELOPMENT - Vikram Abrol, Ketan Shah. Abstract Operating in a business environment governed by speed and agility, IT companies are under constant and immense pressure to reduce time-to-market and enhance product quality. The birth of the Agile approach and models like Scrum owe their existence to this need driving managers to find better solutions. Looking to achieve a faster and more efficient software development cycle (SDC), IT companies have adopted certain methodologies, such as the Lean approach, from the manufacturing industry – another business where speed and efficiency hold the key to profitability. The concept of Kanban also originated in the manufacturing space and has filtered into the IT industry several years ago as an effective approach to manage SDC. The terminology related to Kanban in manufacturing context comes mostly from Toyota Motor Corporation in Japan where the system was invented. The Japanese term Kanban literally means a visual card or a signboard. Hence the Kanban system of work management essentially focuses on visualizing the workflow in order to reduce constraints and minimize the work-in- progress (WIP).

First, the project manager estimates the size of the project and identifies the tasks that need to be performed. Next, he or she staffs the project and puts several activities in place to help coordinate project activities. These steps produce important project man- agement deliverables, including the workplan, staffing plan, and standards list. OBJECTIVES I Become familiar with estimation.
