Testing and Audit of Software projects

The quality of the product is directly related to the quality of the development process. We have undertaken manual testing and audit of software based systems. Some of the common problems in the projects and failures encountered in the product are listed below.

Problems observed in Projects

User requirements (RFP/ Contract) Missing/ Inadequately defined

Key Requirements (RFP/ Contract) Not implemented/ Partially implemented, deviations in requirements and requirements deferred

Architectural Deviations - Interoperability, Security & Performance related problems

Frequent failures/ system crash Fatal errors, data loss & data corruption

Serious problems & functional gaps No proper fixing, temporary workaround

Performance & Scalability Slow response & over utilization of computing resources

Robustness, Stability & Availability Frequent failures & crashes, abnormally long down time & slow recovery

Integration & Interoperability- Incomplete workflow, No data exchange among components & systems

Security of Software & Data Wrongly configured systems, Inadequate authentication, access control and audit logs

Usability Cumbersome & lengthy navigations, poor messaging

Change Control Informal/ unauthorized modifications carried out directly on production system

Digitization & Data Migration Errors Wrong/ unreliable data in the system

Code & Data Synchronization between DC & DR DC/ DR switchover failure

Documentation Issues

Missing/ Incomplete/ Incorrect documentation;
Inconsistency-Among documentation/With application;
Unclear/ ambiguous documentation;
Ineffective document control (change & version control)

Functionality Issues

Run time fatal error, Data loss/ corruption;
Wrong/ incomplete workflows;
Business logic & Data validation errors;
Transactions not traceable/ work items missing, Transactions wrongly rejected;
Wrong calculations & incorrect rules;
Interface problems (payment gateway, bank interface, etc.);
Integration of various modules/ functions of the software not done;
Interoperability problems among software modules

Web Site/Portal Issues

Inconsistent Home/ Web pages;
Missing/ Broken links - Site links not working;
Accessibility requirements as per W3C hardly met;
Incorrect/ Obsolete contents;
Important buttons/ keys disabled;
Site map not available;
Search function not available/ not working

Performance Issues

Extremely slow Home/ Web page loading, document downloading & uploading;
Inability of system to sustain increase in transactions/ data volume;
System crash at much lower users load as against specified requirements;
Over utilization of system resources such as CPU, Memory, BW, etc.

Security Issues

Weak Application Security; (SQL Injection, Privilege escalation, Data loss, Access Control, Error handling/ Information leakage, Session Management, Denial of Services, Audit logs, etc.)
Missing/ ineffective security policy (E.g., Password policy);
Mis-configured/ vulnerable systems such as servers, firewalls, etc;
Improper authentication & access control (access rights & authorizations);
Inadequate confidentiality/ integrity (credentials transmitted in clear text) ;
Risk assessment & BCP not done/ not tested;
Inappropriate data backup & archival for disaster recovery;
Inadequate physical security;

Usability Issues

Cumbersome/ lengthy navigation;
Poor/ missing user instructions/ Help functions;
Improper/ misleading messages for users;
Accessibility requirements not addressed properly

Project in Zambia

We managed US $2.3 million project of laying Optical Fibre cable and setting up antennas on Mobile Telephone towers in Malawi and Zambia.
