Why did you choose Gantt Chart?

Why did you choose Gantt Chart?


Gantt chart is considered as the most important component in project management tools.
Our project schedule of SILKROAD can also be demonstrated by this Gantt chart. We had been searching for Gantt component which can adequately fit to SILKROAD quite a while and finally concluded that Gantt Chart is the best for it. 


To select the perfect tool for own use, we set priorities as below criteria;

  - JavaScript based component to be compatible with popular web browsers.

  - Input a task schedule only with mouse actions.

  - Easy to set dependency between tasks.

  - Resource Management.

  - Hierarchical Tree View.

  - Modify Tasks only with mouse actions. 


Consequently, we came into an end that Gantt Chart is more than enough to satisfy all above criteria and we decided to adopt it as appropriate tool. With lack of Ext JS experiences, we had no hassle to implement Gantt chart with it. Easy usability is the strongest feature of Gantt Chart as a word. 


Implementation Details


SILKROAD, an application lifecycle management system, should have project management system. Most people are very familiar with Gantt chart to manage their project. We adopted Gantt Chart for our project management system. It has also an additional function to import MS-Project file as well as general schedule management function. We have planned to implement ‘timeline’ feature on SILKROAD. We selected Ext Scheduler as a component for it. We expect it can be the best UX for our users.

RM ROI (Requirement Management Return on Investment)


Requirement management tools increase work efficiency, staff productivity while reducing development costs and efforts and time consumed. You should analyze return on investment of new process or tools which has been implemented. 

Return on Investment (ROI) is a popular method of measuring the success of process improvements and IT investments. The simplest method is the Benefit to Cost Ration; this if obtained simply by dividing the benefits by the costs.


1.1 Typical sources of costs: 

     - IT investments, including ongoing maintenance

     - Training staff in new processes and IT tools

     - Consulting needed to assist process change and IT installation

     - Recurring cost associated with new process and IT


1.2 Typical benefits:

     - Increased revenue such as increased sales and sales margins

     - Retention of sales that would otherwise have been lost

     - Reduction in operating expense, for instance daily time savings, eliminated rework




2. Calculating the ROI

There is no question that a requirement management tool is very useful, but can it pay for itself at your company? In Dean Leffingwell’s paper Calculating Your Return on Investment from More Effective Requirements Management, he advances this model for estimating ROI (numbers are from his example) 



You can simply divide the cost saving by the investment (this might be purchase price of the Requirement management tool)

We begin by making a number of working assumptions and conventions that will be used throughout the ROI model. 


2.1 The Cost

This ROI calculation takes into account the total of ownership for requirements management and compares it to the cost saving achieved from the benefits. The fields are variables adjust to accommodate your company. Numbers are from “More effective Requirements Management” by Dean Leffingwell. 

- RM solution investment



- Team’s time & Rigor


2.2 The incremental benefits far outweigh incremental costs.

- Avoiding the cost of lost requirements


Team efficiency cost saving


Avoiding cost of unnecessary development
