/4INDePT | Process Methodology Overview INDePT methodology is designed to provide flexibility, visibility and

productivity to the whole life cycle of product development.

INDePT methodology is agile, incremental and highly iterative.

Six major attributes in the process: – Customer Problems, – Questions, – Functionality, – Feature Sets, – Features– Metrics.


/5INDePT | Process IterationsThere are five major iterations in a process:

1.Customer Problem Domain Analysis;

2.System Functionality and Objects Analysis;

3.System Design;

4.Prototyping and Object Architecture;

5.Features Partition and Coding and Rollout iterations.


/6INDePT | PhasesOverall, methodology consists of three generic phases: 1) Analysis 2) Design and Development 3) Rollout.

Each phase represents a number of iterations with numerous inspections.

The main principle of the process is timely communication, visible progress and monitored productivity and efficiency.


/7INDePT | Analysis phase Iteration 1 - Customer Problem Domain Analysis:– An initial project-wide iteration conducted by problem domain experts/analysts at customer

site (preferable). – A high-level walkthrough of the scope of the system and its context

is performed. – Detailed domain walkthroughs are then held for each area to be modeled and developed. – Normally takes 2 iterations (for small-scale projects 1 iteration should be sufficient).

Iteration 2 - System Functionality and Objects Analysis:– Continuation of the initial process focus is placed on functionality of the system. – Normally takes 2-3 iterations for middle-large scale projects


/8INDePT | Design and Development phase Iteration 1 - System Design, Prototyping and Objects Architecture Iteration:– Refines the functionality of the system to the feature set level of granularity and initial

description of the features.– Functional prototype presents the major functionality. – System design and architecture is formed with detailed definition of objects definition and

dependencies. – Normally 3-5 iterations for middle-large scale projects

Iteration 2 - Features Partition and Coding Iteration:– Activity with domain and development members under the guidance of Project Manager and

Chief Architect. – A low-level module partitioning (feature level) is performed and appropriate feature

sets/features are added into the Project Plan with commitment dates. – Normally 2-3 iterations for middle-large scale projects.


/9INDePT | MetricsProcess metrics provides factual information on current team productivity and performance patterns and enable managers to asses the current progress with maximum visibility and realistic information.

Quantitative metrics:–Actual/Planned Completion Date for the Feature;–Actual/Planned Completion Date for the Feature Set;–Number of days spent on Analysis Iterations–Number of Defects found in Feature Set–Number of Open/Closed Defects–Number of Assigned (Open) Defects per Developer

Qualitative metrics:–Number of Severity (1, 2) Defects per Developer–Complexity Ranking of the Modules–Urgency Ranking of the Modules


/10INDePT | Rollout IterationRollout iteration provides integration and configuration of the whole system online or on customer site.

–Activity with domain and development members under the guidance of Project Managers from both sides. –Developed modules are configured and released online. –Major module inspections/documentation/testing procedures are reviewed and verified
